+
+
+Alibaba Cloud Client for PHP 是帮助 PHP 开发者管理凭据、发送请求的客户端工具，[Alibaba Cloud SDK for PHP][SDK] 由本工具提供底层支持。
+
+
+## 使用诊断
+[Troubleshoot](https://troubleshoot.api.aliyun.com/?source=github_sdk) 提供 OpenAPI 使用诊断服务，通过 `RequestID` 或 `报错信息` ，帮助开发者快速定位，为开发者提供解决方案。
+
+## 在线示例
+[阿里云 OpenAPI 开发者门户]https://next.api.aliyun.com/) 提供在线调用阿里云产品，并动态生成 SDK 代码和快速检索接口等能力，能显著降低使用云 API 的难度。
+
+
+## 先决条件
+您的系统需要满足[先决条件](/docs/zh-CN/0-Prerequisites.md)，包括 PHP> = 5.5。 我们强烈建议使用cURL扩展，并使用TLS后端编译cURL 7.16.2+。
+
+
+## 安装依赖
+如果已在系统上[全局安装 Composer](https://getcomposer.org/doc/00-intro.md#globally)，请直接在项目目录中运行以下内容来安装 Alibaba Cloud Client for PHP 作为依赖项：
+```
+composer require alibabacloud/client
+```
+> 一些用户可能由于网络问题无法安装，可以使用[阿里云 Composer 全量镜像](https://developer.aliyun.com/composer)。
+
+请看[安装](/docs/zh-CN/1-Installation.md)有关通过 Composer 和其他方式安装的详细信息。
+
+
+## 快速使用
+在您开始之前，您需要注册阿里云帐户并获取您的[凭证](https://usercenter.console.aliyun.com/#/manage/ak)。
+
+```php
+<?php
+
+use AlibabaCloud\Client\AlibabaCloud;
+
+AlibabaCloud::accessKeyClient('accessKeyId', 'accessKeySecret')->asDefaultClient();
+```
+
+
+## 请求
+> 请求风格分为 `ROA` 和 `RPC`，不同产品风格不同，使用前，请参考产品文档。推荐使用 [Alibaba Cloud SDK for PHP][SDK] ，细节已被封装，无需关心风格。
+
+
+### ROA 请求
+```php
+<?php
+
+use AlibabaCloud\Client\AlibabaCloud;
+use AlibabaCloud\Client\Exception\ClientException;
+use AlibabaCloud\Client\Exception\ServerException;
+
+try {
+    $result = AlibabaCloud::roa()
+                          ->regionId('cn-hangzhou') // 指定请求的区域，不指定则使用客户端区域、默认区域
+                          ->product('CS') // 指定产品
+                          ->version('2015-12-15') // 指定产品版本
+                          ->action('DescribeClusterServices') // 指定产品接口
+                          ->serviceCode('cs') // 设置 ServiceCode 以备寻址，非必须
+                          ->endpointType('openAPI') // 设置类型，非必须
+                          ->method('GET') // 指定请求方式
+                          ->host('cs.aliyun.com') // 指定域名则不会寻址，如认证方式为 Bearer Token 的服务则需要指定
+                          ->pathPattern('/clusters/[ClusterId]/services') // 指定ROA风格路径规则
+                          ->withClusterId('123456') // 为路径中参数赋值，方法名：with + 参数
+                          ->request(); // 发起请求并返回结果对象，请求需要放在设置的最后面
+
+    print_r($result->toArray());
+    
+} catch (ClientException $exception) {
+    print_r($exception->getErrorMessage());
+} catch (ServerException $exception) {
+    print_r($exception->getErrorMessage());
+}
+```
+
+### RPC 请求
+```php
+<?php
+
+use AlibabaCloud\Client\AlibabaCloud;
+use AlibabaCloud\Client\Exception\ClientException;
+use AlibabaCloud\Client\Exception\ServerException;
+
+try {
+    $result = AlibabaCloud::rpc()
+                          ->product('Cdn')
+                          ->version('2014-11-11')
+                          ->action('DescribeCdnService')
+                          ->method('POST')
+                          ->request();
+
+    print_r($result->toArray());
+
+} catch (ClientException $exception) {
+    print_r($exception->getErrorMessage());
+} catch (ServerException $exception) {
+    print_r($exception->getErrorMessage());
+}

+
+Alibaba Cloud Client for PHP is a client tool that helps PHP developers manage credentials and send requests, [Alibaba Cloud SDK for PHP][SDK] dependency on this tool.
+
+## Troubleshoot
+[Troubleshoot](https://troubleshoot.api.aliyun.com/?source=github_sdk) Provide OpenAPI diagnosis service to help developers locate quickly and provide solutions for developers through `RequestID` or `error message`.
+
+## Online Demo
+[Alibaba Cloud OpenAPI Developer Portal](https://next.api.aliyun.com/) provides the ability to call the cloud product OpenAPI online, and dynamically generate SDK Example code and quick retrieval interface, which can significantly reduce the difficulty of using the cloud API.
+
+## Prerequisites
+Your system will need to meet the [Prerequisites](/docs/en-US/0-Prerequisites.md), including having PHP >= 5.5. We highly recommend having it compiled with the cURL extension and cURL 7.16.2+.
+
+
+## Installation
+If Composer is already [installed globally on your system](https://getcomposer.org/doc/00-intro.md#globally), run the following in the base directory of your project to install Alibaba Cloud Client for PHP as a dependency:
+```
+composer require alibabacloud/client
+```
+> Some users may not be able to install due to network problems, you can try to switch the Composer mirror.
+
+Please see the [Installation](/docs/en-US/1-Installation.md) for more detailed information about installing the Alibaba Cloud Client for PHP through Composer and other means.
+
+
+## Quick Examples
+Before you begin, you need to sign up for an Alibaba Cloud account and retrieve your [Credentials](https://usercenter.console.aliyun.com/#/manage/ak).
+
+### Create Client
+```php
+<?php
+
+use AlibabaCloud\Client\AlibabaCloud;
+
+AlibabaCloud::accessKeyClient('accessKeyId', 'accessKeySecret')->asDefaultClient();
+```
+
+
+## Request
+> Request styles are divided into `ROA` and `RPC`. Different product styles are different. Please refer to the product documentation before using. It is recommended to use [Alibaba cloud SDK for PHP][SDK], the details have been encapsulated, and you do not need to care about the style.
+
+
+### ROA Request
+```php
+<?php
+
+use AlibabaCloud\Client\AlibabaCloud;
+use AlibabaCloud\Client\Exception\ClientException;
+use AlibabaCloud\Client\Exception\ServerException;
+
+try {
+    $result = AlibabaCloud::roa()
+                          ->regionId('cn-hangzhou') // Specify the requested regionId, if not specified, use the client regionId, then default regionId

+                          ->host('cs.aliyun.com') // Location Service will not be enabled if the host is specified. For example, service with a Certification type-Bearer Token should be specified
+                          ->pathPattern('/clusters/[ClusterId]/services') // Specify path rule with ROA-style
+                          ->withClusterId('123456') // Assign values to parameters in the path. Method: with + Parameter
+                          ->request(); // Make a request and return to result object. The request is to be placed at the end of the setting
+                          
+    print_r($result->toArray());
+    
+} catch (ClientException $exception) {

+# weblibs-configmanager
+weblibs-configmanager is a tool library for easily read and access to php config array file and direct read/write configuration file / object.
+
+## Why use weblibs-configmanager ?
+The purpose of this project is to propose a simple and lightweight library to manage php hierarchical configuration files.
+
+## Supported formats
+
+This package supports config files in the following format:
+
+Format | Component | Since version |  Description
+:---: | :---: | :---: | ---
+Array | `ConfigManager` | `v0.1.0` |  Deprecated, legacy name for the php array reader, only for compatibility support
+Array | `ArrayConfigManager` | `v1.2.0` | A file that returns a php array, the original supported format
+Yaml | `YamlConfigManager` | `v1.3.0` | A file containing a valid YAML file
+JSON | `JsonConfigManager` | `v1.4.0` | A file containing a valid JSON file
+
+All the supported format are parsed and internally handled in the same way granting the same functionalities.
+
+## Installation
+The recommended way to install weblibs-configmanager is through [Composer](https://getcomposer.org).
+```bash
+composer require clagiordano/weblibs-configmanager
+```
+
+## Usage examples (Array format)
+
+### Write a sample config file like this
+```php
+<?php
+
+return array (
+  'app' => 'app_name',
+  'db' => 
+  array (
+    'host' => 'localhost',
+    'user' => 'sample_user',
+    'pass' => 'sample_pass',
+    'port' => 3306,
+  ),
+  'other' => 
+  array (
+    'multi' => 
+    array (
+      'deep' => 
+      array (
+        'nested' => 'config_value',
+      ),
+    ),
+  ),
+);
+
+```
+
+### Instance ConfigManager object
+
+```php
+use clagiordano\weblibs\configmanager\ConfigManager;
+
+/**
+ * Instance object to read argument file
+ */
+$config = new ConfigManager("configfile.php");
+```
+
+### Check if a value exists into config file
+
+```php
+/**
+ * Check if a value exists into config file
+ */
+$value = $config->existValue('app');
+```
+
+### Read a simple element from config file
+
+```php
+/**
+ * Read a simple element from config file
+ */
+$value = $config->getValue('app');
+```
+
+### Access to a nested element from config
+
+```php
+/**
+ * Access to a nested element from config
+ */
+$nestedValue = $config->getValue('other.multi.deep.nested');
+```
+
+### Change config value at runtime
+
+```php
+/**
+ * Change config value at runtime
+ */
+$this->config->setValue('other.multi.deep.nested', "SUPERNESTED");
+```
+
+### Save config file with original name (OVERWRITE) 
+
+```php
+/**
+ * Save config file with original name (OVERWRITE) 
+ */
+$this->config->saveConfigFile();
+```
+
+### Or save config file with a different name
+
+```php
+/**
+ * Save config file with original name (OVERWRITE) 
+ */
+$this->config->saveConfigFile('/new/file/name/or/path/test.php');
+```
+
+### Optionally you can also reload config file from disk after save
+
+```php
+/**
+ * Optionally you can also reload config file from disk after save
+ */
+$this->config->saveConfigFile('/new/file/name/or/path/test.php', true);
+```
+
+### Load another configuration file without reinstance ConfigManager
+
+```php
+/**
+ * Load another configuration file without reinstance ConfigManager
+ */
+$this->config->loadConfig('another_config_file.php');
+```

+## Why?
+
+In part due to a lack of multibyte support (including UTF-8) across many of
+PHP's standard string functions. But also to offer an OO wrapper around the
+`mbstring` module's multibyte-compatible functions. Stringy handles some quirks,
+provides additional functionality, and hopefully makes strings a little easier
+to work with!
+
+```php
+// Standard library
+strtoupper('fòôbàř');       // 'FòôBàř'
+strlen('fòôbàř');           // 10
+
+// mbstring
+mb_strtoupper('fòôbàř');    // 'FÒÔBÀŘ'
+mb_strlen('fòôbàř');        // '6'
+
+// Stringy
+s('fòôbàř')->toUpperCase(); // 'FÒÔBÀŘ'
+s('fòôbàř')->length();      // '6'
+```
+
+## Installation
+
+If you're using Composer to manage dependencies, you can include the following
+in your composer.json file:
+
+```json
+"require": {
+    "danielstjules/stringy": "~3.1.0"
+}
+```
+
+Then, after running `composer update` or `php composer.phar update`, you can
+load the class using Composer's autoloading:
+
+```php
+require 'vendor/autoload.php';
+```
+
+Otherwise, you can simply require the file directly:
+
+```php
+require_once 'path/to/Stringy/src/Stringy.php';
+```
+
+And in either case, I'd suggest using an alias.
+
+```php
+use Stringy\Stringy as S;
+```
+
+Please note that Stringy relies on the `mbstring` module for its underlying
+multibyte support. If the module is not found, Stringy will use
+[symfony/polyfill-mbstring](https://github.com/symfony/polyfill-mbstring).
+ex-mbstring is a non-default, but very common module. For example, with debian
+and ubuntu, it's included in libapache2-mod-php5, php5-cli, and php5-fpm. For
+OSX users, it's a default for any version of PHP installed with homebrew.
+If compiling PHP from scratch, it can be included with the
+`--enable-mbstring` flag.
+
+## OO and Chaining
+
+The library offers OO method chaining, as seen below:
+
+```php
+use Stringy\Stringy as S;
+echo S::create('fòô     bàř')->collapseWhitespace()->swapCase(); // 'FÒÔ BÀŘ'
+```
+
+`Stringy\Stringy` has a __toString() method, which returns the current string
+when the object is used in a string context, ie:
+`(string) S::create('foo')  // 'foo'`
+
+## Implemented Interfaces
+
+`Stringy\Stringy` implements the `IteratorAggregate` interface, meaning that
+`foreach` can be used with an instance of the class:
+
+``` php
+$stringy = S::create('fòôbàř');
+foreach ($stringy as $char) {
+    echo $char;
+}
+// 'fòôbàř'
+```
+
+It implements the `Countable` interface, enabling the use of `count()` to
+retrieve the number of characters in the string:
+
+``` php
+$stringy = S::create('fòô');
+count($stringy);  // 3
+```
+
+Furthermore, the `ArrayAccess` interface has been implemented. As a result,
+`isset()` can be used to check if a character at a specific index exists. And
+since `Stringy\Stringy` is immutable, any call to `offsetSet` or `offsetUnset`
+will throw an exception. `offsetGet` has been implemented, however, and accepts
+both positive and negative indexes. Invalid indexes result in an
+`OutOfBoundsException`.
+
+``` php
+$stringy = S::create('bàř');
+echo $stringy[2];     // 'ř'
+echo $stringy[-2];    // 'à'
+isset($stringy[-4]);  // false
+
+$stringy[3];          // OutOfBoundsException
+$stringy[2] = 'a';    // Exception
+```
+
+## PHP 5.6 Creation
+
+As of PHP 5.6, [`use function`](https://wiki.php.net/rfc/use_function) is
+available for importing functions. Stringy exposes a namespaced function,
+`Stringy\create`, which emits the same behaviour as `Stringy\Stringy::create()`.
+If running PHP 5.6, or another runtime that supports the `use function` syntax,
+you can take advantage of an even simpler API as seen below:
+
+``` php
+use function Stringy\create as s;
+
+// Instead of: S::create('fòô     bàř')
+s('fòô     bàř')->collapseWhitespace()->swapCase();
+```
+
+## StaticStringy
+
+All methods listed under "Instance methods" are available as part of a static
+wrapper. For StaticStringy methods, the optional encoding is expected to be the
+last argument. The return value is not cast, and may thus be of type Stringy,
+integer, boolean, etc.
+
+```php
+use Stringy\StaticStringy as S;
+
+// Translates to Stringy::create('fòôbàř')->slice(0, 3);
+// Returns a Stringy object with the string "fòô"
+S::slice('fòôbàř', 0, 3);
+```
+
+## Class methods
+
+##### create(mixed $str [, $encoding ])
+
+Creates a Stringy object and assigns both str and encoding properties
+the supplied values. $str is cast to a string prior to assignment, and if
+$encoding is not specified, it defaults to mb_internal_encoding(). It
+then returns the initialized object. Throws an InvalidArgumentException
+if the first argument is an array or object without a __toString method.
+
+```php
+$stringy = S::create('fòôbàř'); // 'fòôbàř'
+```
+
+## Instance Methods
+
+Stringy objects are immutable. All examples below make use of PHP 5.6
+function importing, and PHP 5.4 short array syntax. They also assume the
+encoding returned by mb_internal_encoding() is UTF-8. For further details,
+see the documentation for the create method above, as well as the notes
+on PHP 5.6 creation.
+
+##### append(string $string)

+```
+
+##### contains(string $needle [, boolean $caseSensitive = true ])

+```
+
+##### countSubstr(string $substring [, boolean $caseSensitive = true ])
+
+Returns the number of occurrences of $substring in the given string.

+s('author_id')->humanize(); // 'Author'
+```
+
+##### indexOf(string $needle [, $offset = 0 ]);
+
+Returns the index of the first occurrence of $needle in the string,
+and false if not found. Accepts an optional offset from which to begin

+s('A102F')->isHexadecimal(); // true
+```
+
+##### isJson()
+
+Returns true if the string is JSON, false otherwise. Unlike json_decode
+in PHP 5.x, this method is consistent with PHP 7 and other JSON parsers,
+in that an empty string is not considered valid JSON.
+
+```php
+s('{"foo":"bar"}')->isJson(); // true
+```
+
+##### isLowerCase()
+
+Returns true if the string contains only lower case chars, false otherwise.

+s('foobar')->longestCommonPrefix('foobaz'); // 'fooba'
+```
+
+##### longestCommonSuffix(string $otherStr)
+
+Returns the longest common suffix between the string and $otherStr.
+
+```php
+s('fòôbàř')->longestCommonSuffix('fòrbàř'); // 'bàř'
+```
+
+##### longestCommonSubstring(string $otherStr)

+
+##### pad(int $length [, string $padStr = ' ' [, string $padType = 'right' ]])
+
+Pads the string to a given length with $padStr. If length is less than
+or equal to the length of the string, no padding takes places. The default
+string used for padding is a space, and the default type (one of 'left',
+'right', 'both') is 'right'. Throws an InvalidArgumentException if
+$padType isn't one of those 3 values.
+
+```php
+s('fòôbàř')->pad(9, '-/', 'left'); // '-/-fòôbàř'
+```
+
+##### padBoth(int $length [, string $padStr = ' ' ])
+
+Returns a new string of a given length such that both sides of the string
+string are padded. Alias for pad() with a $padType of 'both'.

+```
+
+##### padLeft(int $length [, string $padStr = ' ' ])
+
+Returns a new string of a given length such that the beginning of the
+string is padded. Alias for pad() with a $padType of 'left'.

+```
+
+##### padRight(int $length [, string $padStr = ' ' ])
+
+Returns a new string of a given length such that the end of the string is
+padded. Alias for pad() with a $padType of 'right'.

+```
+
+##### regexReplace(string $pattern, string $replacement [, string $options = 'msr'])
+
+Replaces all occurrences of $pattern in $str by $replacement. An alias
+for mb_ereg_replace(). Note that the 'i' option with multibyte patterns
+in mb_ereg_replace() requires PHP 5.6+ for correct results. This is due
+to a lack of support in the bundled version of Oniguruma in PHP < 5.6,
+and current versions of HHVM (3.8 and below).
+
+```php
+s('fòô ')->regexReplace('f[òô]+\s', 'bàř'); // 'bàř'
+s('fò')->regexReplace('(ò)', '\\1ô'); // 'fòô'
+```

+
+```php
+s('fòôbàř')->removeRight('bàř'); // 'fòô'
+```
+
+##### repeat(int $multiplier)

+##### replace(string $search, string $replacement)
+
+Replaces all occurrences of $search in $str by $replacement.
+
+```php
+s('fòô bàř fòô bàř')->replace('fòô ', ''); // 'bàř bàř'
+```
+
+##### reverse()
+
+Returns a reversed string. A multibyte version of strrev().
+
+```php
+s('fòôbàř')->reverse(); // 'řàbôòf'
+```
+
+##### safeTruncate(int $length [, string $substring = '' ])
+
+Truncates the string to a given length, while ensuring that it does not
+split words. If $substring is provided, and truncating occurs, the
+string is further truncated so that the substring may be appended without
+exceeding the desired length.
+
+```php
+s('What are your plans today?')->safeTruncate(22, '...');
+// 'What are your plans...'
+```
+
+##### shuffle()
+
+A multibyte str_shuffle() function. It returns a string with its characters in
+random order.
+
+```php
+s('fòôbàř')->shuffle(); // 'àôřbòf'
+```
+
+##### slugify([, string $replacement = '-' [, string $language = 'en']])
+
+Converts the string into an URL slug. This includes replacing non-ASCII
+characters with their closest ASCII equivalents, removing remaining
+non-ASCII and non-alphanumeric characters, and replacing whitespace with
+$replacement. The replacement defaults to a single dash, and the string
+is also converted to lowercase. The language of the source string can
+also be supplied for language-specific transliteration.
+
+```php
+s('Using strings like fòô bàř')->slugify(); // 'using-strings-like-foo-bar'
+```
+
+##### slice(int $start [, int $end ])
+
+Returns the substring beginning at $start, and up to, but not including
+the index specified by $end. If $end is omitted, the function extracts
+the remaining string. If $end is negative, it is computed from the end
+of the string.
+
+```php
+s('fòôbàř')->slice(3, -1); // 'bà'
+```
+
+##### split(string $pattern [, int $limit ])
+
+Splits the string with the provided regular expression, returning an
+array of Stringy objects. An optional integer $limit will truncate the
+results.
+
+```php
+s('foo,bar,baz')->split(',', 2); // ['foo', 'bar']
+```
+
+##### startsWith(string $substring [, boolean $caseSensitive = true ])
+
+Returns true if the string begins with $substring, false otherwise.
+By default, the comparison is case-sensitive, but can be made insensitive
+by setting $caseSensitive to false.
+
+```php
+s('FÒÔbàřbaz')->startsWith('fòôbàř', false); // true
+```
+
+##### startsWithAny(string[] $substrings [, boolean $caseSensitive = true ])
+
+Returns true if the string begins with any of $substrings, false
+otherwise. By default the comparison is case-sensitive, but can be made
+insensitive by setting $caseSensitive to false.
+
+```php
+s('FÒÔbàřbaz')->startsWithAny(['fòô', 'bàř'], false); // true
+```
+
+##### stripWhitespace()
+
+Strip all whitespace characters. This includes tabs and newline
+characters, as well as multibyte whitespace such as the thin space
+and ideographic space.
+
+```php
+s('   Ο     συγγραφέας  ')->stripWhitespace(); // 'Οσυγγραφέας'
+```
+
+##### substr(int $start [, int $length ])
+
+Returns the substring beginning at $start with the specified $length.
+It differs from the mb_substr() function in that providing a $length of
+null will return the rest of the string, rather than an empty string.
+
+```php
+s('fòôbàř')->substr(2, 3); // 'ôbà'
+```
+
+##### surround(string $substring)
+
+Surrounds a string with the given substring.
+
+```php
+s(' ͜ ')->surround('ʘ'); // 'ʘ ͜ ʘ'
+```
+
+##### swapCase()
+
+Returns a case swapped version of the string.
+
+```php
+s('Ντανιλ')->swapCase(); // 'νΤΑΝΙΛ'
+```
+
+##### tidy()
+
+Returns a string with smart quotes, ellipsis characters, and dashes from
+Windows-1252 (commonly used in Word documents) replaced by their ASCII equivalents.
+
+```php
+s('“I see…”')->tidy(); // '"I see..."'
+```
+
+##### titleize([, array $ignore])
+
+Returns a trimmed string with the first letter of each word capitalized.
+Also accepts an array, $ignore, allowing you to list words not to be
+capitalized.
+
+```php
+$ignore = ['at', 'by', 'for', 'in', 'of', 'on', 'out', 'to', 'the'];
+s('i like to watch television')->titleize($ignore);
+// 'I Like to Watch Television'
+```
+
+##### toAscii([, string $language = 'en' [, bool $removeUnsupported = true ]])
+
+Returns an ASCII version of the string. A set of non-ASCII characters are
+replaced with their closest ASCII counterparts, and the rest are removed
+by default. The language or locale of the source string can be supplied
+for language-specific transliteration in any of the following formats:
+en, en_GB, or en-GB. For example, passing "de" results in "äöü" mapping
+to "aeoeue" rather than "aou" as in other languages.
+
+```php
+s('fòôbàř')->toAscii(); // 'foobar'
+s('äöü')->toAscii(); // 'aou'
+s('äöü')->toAscii('de'); // 'aeoeue'
+```
+
+##### toBoolean()
+
+Returns a boolean representation of the given logical string value.
+For example, 'true', '1', 'on' and 'yes' will return true. 'false', '0',
+'off', and 'no' will return false. In all instances, case is ignored.
+For other numeric strings, their sign will determine the return value.
+In addition, blank strings consisting of only whitespace will return
+false. For all other strings, the return value is a result of a
+boolean cast.
+
+```php
+s('OFF')->toBoolean(); // false
+```
+
+##### toLowerCase()
+
+Converts all characters in the string to lowercase. An alias for PHP's
+mb_strtolower().
+
+```php
+s('FÒÔBÀŘ')->toLowerCase(); // 'fòôbàř'
+```
+
+##### toSpaces([, tabLength = 4 ])
+
+Converts each tab in the string to some number of spaces, as defined by
+$tabLength. By default, each tab is converted to 4 consecutive spaces.
+
+```php
+s(' String speech = "Hi"')->toSpaces(); // '    String speech = "Hi"'
+```
+
+##### toTabs([, tabLength = 4 ])
+
+Converts each occurrence of some consecutive number of spaces, as defined
+by $tabLength, to a tab. By default, each 4 consecutive spaces are
+converted to a tab.
+
+```php
+s('    fòô    bàř')->toTabs();
+// '   fòô bàř'
+```
+
+##### toTitleCase()
+
+Converts the first character of each word in the string to uppercase.
+
+```php
+s('fòô bàř')->toTitleCase(); // 'Fòô Bàř'
+```
+
+##### toUpperCase()
+
+Converts all characters in the string to uppercase. An alias for PHP's
+mb_strtoupper().
+
+```php
+s('fòôbàř')->toUpperCase(); // 'FÒÔBÀŘ'
+```
+
+##### trim([, string $chars])
+
+Returns a string with whitespace removed from the start and end of the
+string. Supports the removal of unicode whitespace. Accepts an optional
+string of characters to strip instead of the defaults.
+
+```php
+s('  fòôbàř  ')->trim(); // 'fòôbàř'
+```
+
+##### trimLeft([, string $chars])
+
+Returns a string with whitespace removed from the start of the string.
+Supports the removal of unicode whitespace. Accepts an optional
+string of characters to strip instead of the defaults.
+
+```php
+s('  fòôbàř  ')->trimLeft(); // 'fòôbàř  '
+```
+
+##### trimRight([, string $chars])
+
+Returns a string with whitespace removed from the end of the string.
+Supports the removal of unicode whitespace. Accepts an optional
+string of characters to strip instead of the defaults.
+
+```php
+s('  fòôbàř  ')->trimRight(); // '  fòôbàř'
+```
+
+##### truncate(int $length [, string $substring = '' ])
+
+Truncates the string to a given length. If $substring is provided, and
+truncating occurs, the string is further truncated so that the substring
+may be appended without exceeding the desired length.
+
+```php
+s('What are your plans today?')->truncate(19, '...'); // 'What are your pl...'
+```
+
+##### underscored()
+
+Returns a lowercase and trimmed string separated by underscores.
+Underscores are inserted before uppercase characters (with the exception
+of the first character of the string), and in place of spaces as well as dashes.
+
+```php
+s('TestUCase')->underscored(); // 'test_u_case'
+```
+
+##### upperCamelize()
+
+Returns an UpperCamelCase version of the supplied string. It trims
+surrounding spaces, capitalizes letters following digits, spaces, dashes
+and underscores, and removes spaces, dashes, underscores.
+
+```php
+s('Upper Camel-Case')->upperCamelize(); // 'UpperCamelCase'
+```
+
+##### upperCaseFirst()
+
+Converts the first character of the supplied string to upper case.
+
+```php
+s('σ foo')->upperCaseFirst(); // 'Σ foo'
+```

+		  GNU LESSER GENERAL PUBLIC LICENSE
+		       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.

+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+		  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
+
+  <signature of Ty Coon>, 1 April 1990
+  Ty Coon, President of Vice
+
+That's all there is to it!

+HTML Purifier [![Build Status](https://secure.travis-ci.org/ezyang/htmlpurifier.svg?branch=master)](http://travis-ci.org/ezyang/htmlpurifier)
+=============
+
+HTML Purifier is an HTML filtering solution that uses a unique combination
+of robust whitelists and aggressive parsing to ensure that not only are
+XSS attacks thwarted, but the resulting HTML is standards compliant.
+
+HTML Purifier is oriented towards richly formatted documents from
+untrusted sources that require CSS and a full tag-set.  This library can
+be configured to accept a more restrictive set of tags, but it won't be
+as efficient as more bare-bones parsers. It will, however, do the job
+right, which may be more important.
+
+Places to go:
+
+* See INSTALL for a quick installation guide
+* See docs/ for developer-oriented documentation, code examples and
+  an in-depth installation guide.
+* See WYSIWYG for information on editors like TinyMCE and FCKeditor
+
+HTML Purifier can be found on the web at: [http://htmlpurifier.org/](http://htmlpurifier.org/)

+ * HTML Purifier is an HTML filter that will take an arbitrary snippet of
+ * HTML and rigorously test, validate and filter it into a version that
+ * is safe for output onto webpages. It achieves this by:
+ *
+ *  -# Lexing (parsing into tokens) the document,
+ *  -# Executing various strategies on the tokens:
+ *      -# Removing all elements not in the whitelist,
+ *      -# Making the tokens well-formed,
+ *      -# Fixing the nesting of the nodes, and
+ *      -# Validating attributes of the nodes; and
+ *  -# Generating HTML from the purified tokens.
+ *
+ * However, most users will only need to interface with the HTMLPurifier
+ * and HTMLPurifier_Config.

+            //    <http://ja.wikipedia.org/wiki/MS_明朝>.  See

+            //    You can see live samples of these on the Internet:
+            //    <http://www.google.co.jp/search?q=font-family+ＭＳ+明朝|ゴシック>
+            //    However, most of these fonts have ASCII equivalents:
+            //    for example, 'MS Mincho', and it's considered
+            //    professional to use ASCII font names instead of
+            //    Unicode font names.  Thanks Takeshi Terada for
+            //    providing this information.
+            //  The following characters, to my knowledge, have not been
+            //  used to name font names.
+            //  - Single quote.  While theoretically you might find a
+            //    font name that has a single quote in its name (serving
+            //    as an apostrophe, e.g. Dave's Scribble), I haven't
+            //    been able to find any actual examples of this.
+            //    Internet Explorer's cssText translation (which I
+            //    believe is invoked by innerHTML) normalizes any
+            //    quoting to single quotes, and fails to escape single
+            //    quotes.  (Note that this is not IE's behavior for all
+            //    CSS properties, just some sort of special casing for
+            //    font-family).  So a single quote *cannot* be used
+            //    safely in the font-family context if there will be an
+            //    innerHTML/cssText translation.  Note that Firefox 3.x
+            //    does this too.
+            //  - Double quote.  In IE, these get normalized to
+            //    single-quotes, no matter what the encoding.  (Fun
+            //    fact, in IE8, the 'content' CSS property gained
+            //    support, where they special cased to preserve encoded
+            //    double quotes, but still translate unadorned double
+            //    quotes into single quotes.)  So, because their
+            //    fixpoint behavior is identical to single quotes, they
+            //    cannot be allowed either.  Firefox 3.x displays
+            //    single-quote style behavior.
+            //  - Backslashes are reduced by one (so \\ -> \) every
+            //    iteration, so they cannot be used safely.  This shows
+            //    up in IE7, IE8 and FF3
+            //  - Semicolons, commas and backticks are handled properly.
+            //  - The rest of the ASCII punctuation is handled properly.
+            // We haven't checked what browsers do to unadorned
+            // versions, but this is not important as long as the
+            // browser doesn't /remove/ surrounding quotes (as IE does
+            // for HTML).
+            //
+            // With these results in hand, we conclude that there are
+            // various levels of safety:
+            //  - Paranoid: alphanumeric, spaces and dashes(?)
+            //  - International: Paranoid + non-ASCII Unicode
+            //  - Edgy: Everything except quotes, backslashes
+            //  - NoJS: Standards compliance, e.g. sod IE. Note that
+            //    with some judicious character escaping (since certain
+            //    types of escaping doesn't work) this is theoretically
+            //    OK as long as innerHTML/cssText is not called.
+            // We believe that international is a reasonable default
+            // (that we will implement now), and once we do more
+            // extensive research, we may feel comfortable with dropping
+            // it down to edgy.
+
+            // Edgy: alphanumeric, spaces, dashes, underscores and Unicode.  Use of

+Lookup table of all allowed link frame targets.  Some commonly used link
+targets include _blank, _self, _parent and _top. Values should be
+lowercase, as validation will be done in a case-sensitive manner despite
+W3C's recommendation. XHTML 1.0 Strict does not permit the target attribute
+so this directive will have no effect in that doctype. XHTML 1.1 does not
+enable the Target module by default, you will have to manually enable it
+(see the module documentation for more details.)

+If null, class will auto-detect the doctype and, if matching XHTML 1.1 or

+is forced; if false, the NMTOKENS definition is forced.  To get behavior
+of HTML Purifier prior to 4.0.0, set this directive to false.
+
+Some rational behind the auto-detection:
+in previous versions of HTML Purifier, it was assumed that the form of
+class was NMTOKENS, as specified by the XHTML Modularization (representing
+XHTML 1.1 and XHTML 2.0).  The DTDs for HTML 4.01 and XHTML 1.0, however
+specify class as CDATA.  HTML 5 effectively defines it as CDATA, but
+with the additional constraint that each name should be unique (this is not
+explicitly outlined in previous specifications).

+AutoFormat.RemoveEmpty
+TYPE: bool
+VERSION: 3.2.0

+--DESCRIPTION--
+<p>
+  When enabled, HTML Purifier will attempt to remove empty elements that
+  contribute no semantic information to the document. The following types
+  of nodes will be removed:
+</p>
+<ul><li>
+    Tags with no attributes and no content, and that are not empty
+    elements (remove <code>&lt;a&gt;&lt;/a&gt;</code> but not
+    <code>&lt;br /&gt;</code>), and
+  </li>
+  <li>
+    Tags with no content, except for:<ul>
+      <li>The <code>colgroup</code> element, or</li>
+      <li>
+        Elements with the <code>id</code> or <code>name</code> attribute,
+        when those attributes are permitted on those elements.
+      </li>
+    </ul></li>
+</ul>
+<p>
+  Please be very careful when using this functionality; while it may not
+  seem that empty elements contain useful information, they can alter the
+  layout of a document given appropriate styling. This directive is most
+  useful when you are processing machine-generated HTML, please avoid using
+  it on regular user HTML.
+</p>
+<p>
+  Elements that contain only whitespace will be treated as empty. Non-breaking
+  spaces, however, do not count as whitespace. See
+  %AutoFormat.RemoveEmpty.RemoveNbsp for alternate behavior.
+</p>
+<p>
+  This algorithm is not perfect; you may still notice some empty tags,
+  particularly if a node had elements, but those elements were later removed
+  because they were not permitted in that context, or tags that, after
+  being auto-closed by another tag, where empty. This is for safety reasons
+  to prevent clever code from breaking validation. The general rule of thumb:
+  if a tag looked empty on the way in, it will get removed; if HTML Purifier
+  made it empty, it will stay.

+  counter measures: an explicit width and height set to auto in all
+  images in your document (unlikely) or the disabling of width and

+    of browsable external resources, which could break things if your redirection
+    script was a splash page or used <code>meta</code> tags. To revert to
+    previous behavior, please use %URI.MungeResources.
+</p>
+<p>
+    You may want to also use %URI.MungeSecretKey along with this directive
+    in order to enforce what URIs your redirector script allows. Open
+    redirector scripts can be a security risk and negatively affect the
+    reputation of your domain name.
+</p>
+<p>
+    Starting with HTML Purifier 3.1.1, there is also these substitutions:

+            <td>1 - The URI embeds a resource<br />(blank) - The URI is merely a link</td>
+            <td></td>
+        </tr>
+        <tr>
+            <td>%n</td>

+            <td></td>
+        </tr>
+    </tbody>
+</table>
+<p>
+    Admittedly, these letters are somewhat arbitrary; the only stipulation
+    was that they couldn't be a through f. r is for resource (I would have preferred
+    e, but you take what you can get), n is for name, m
+    was picked because it came after n (and I couldn't use a), p is for
+    property.

+URI.MungeSecretKey
+TYPE: string/null
+VERSION: 3.1.1
+DEFAULT: NULL
+--DESCRIPTION--
+<p>
+    This directive enables secure checksum generation along with %URI.Munge.
+    It should be set to a secure key that is not shared with anyone else.
+    The checksum can be placed in the URI using %t. Use of this checksum
+    affords an additional level of protection by allowing a redirector
+    to check if a URI has passed through HTML Purifier with this line:
+</p>
+
+<pre>$checksum === hash_hmac("sha256", $url, $secret_key)</pre>
+
+<p>
+    If the output is TRUE, the redirector script should accept the URI.
+</p>
+
+<p>
+    Please note that it would still be possible for an attacker to procure
+    secure hashes en-mass by abusing your website's Preview feature or the
+    like, but this service affords an additional level of protection
+    that should be combined with website blacklisting.
+</p>
+
+<p>
+    Remember this has no effect if %URI.Munge is not on.

+TYPE: string/null

+DEFAULT: NULL
+--DESCRIPTION--
+<p>
+    A PCRE regular expression that will be matched against an iframe URI.  This is
+    a relatively inflexible scheme, but works well enough for the most common
+    use-case of iframes: embedded video.  This directive only has an effect if
+    %HTML.SafeIframe is enabled.  Here are some example values:
+</p>
+<ul>
+    <li><code>%^http://www.youtube.com/embed/%</code> - Allow YouTube videos</li>
+    <li><code>%^http://player.vimeo.com/video/%</code> - Allow Vimeo videos</li>
+    <li><code>%^http://(www.youtube.com/embed/|player.vimeo.com/video/)%</code> - Allow both</li>
+</ul>
+<p>
+    Note that this directive does not give you enough granularity to, say, disable
+    all <code>autoplay</code> videos.  Pipe up on the HTML Purifier forums if this
+    is a capability you want.

+/**
+ * Forgivingly lexes HTML (SGML-style) markup into tokens.
+ *
+ * A lexer parses a string of SGML-style markup and converts them into
+ * corresponding tokens.  It doesn't check for well-formedness, although its
+ * internal mechanism may make this automatic (such as the case of
+ * HTMLPurifier_Lexer_DOMLex).  There are several implementations to choose
+ * from.
+ *
+ * A lexer is HTML-oriented: it might work with XML, but it's not
+ * recommended, as we adhere to a subset of the specification for optimization
+ * reasons. This might change in the future. Also, most tokenizers are not
+ * expected to handle DTDs or PIs.
+ *
+ * This class should not be directly instantiated, but you may use create() to
+ * retrieve a default copy of the lexer.  Being a supertype, this class
+ * does not actually define any implementation, but offers commonly used
+ * convenience functions for subclasses.
+ *
+ * @note The unit tests will instantiate this class for testing purposes, as
+ *       many of the utility functions require a class to be instantiated.
+ *       This means that, even though this class is not runnable, it will
+ *       not be declared abstract.
+ *
+ * @par
+ *
+ * @note
+ * We use tokens rather than create a DOM representation because DOM would:
+ *
+ * @par
+ *  -# Require more processing and memory to create,
+ *  -# Is not streamable, and
+ *  -# Has the entire document structure (html and body not needed).
+ *
+ * @par
+ * However, DOM is helpful in that it makes it easy to move around nodes
+ * without a lot of lookaheads to see when a tag is closed. This is a
+ * limitation of the token system and some workarounds would be nice.

+
+// Note [Injector skips]
+// ~~~~~~~~~~~~~~~~~~~~~
+// When I originally designed this class, the idea behind the 'skip'
+// property of HTMLPurifier_Token was to help avoid infinite loops
+// in injector processing.  For example, suppose you wrote an injector
+// that bolded swear words.  Naively, you might write it so that
+// whenever you saw ****, you replaced it with <strong>****</strong>.
+//
+// When this happens, we will reprocess all of the tokens with the
+// other injectors.  Now there is an opportunity for infinite loop:
+// if we rerun the swear-word injector on these tokens, we might
+// see **** and then reprocess again to get
+// <strong><strong>****</strong></strong> ad infinitum.
+//
+// Thus, the idea of a skip is that once we process a token with
+// an injector, we mark all of those tokens as having "come from"
+// the injector, and we never run the injector again on these
+// tokens.
+//
+// There were two more complications, however:
+//
+//  - With HTMLPurifier_Injector_RemoveEmpty, we noticed that if
+//    you had <b><i></i></b>, after you removed the <i></i>, you
+//    really would like this injector to go back and reprocess
+//    the <b> tag, discovering that it is now empty and can be
+//    removed.  So we reintroduced the possibility of infinite looping
+//    by adding a "rewind" function, which let you go back to an
+//    earlier point in the token stream and reprocess it with injectors.
+//    Needless to say, we need to UN-skip the token so it gets
+//    reprocessed.
+//
+//  - Suppose that you successfuly process a token, replace it with
+//    one with your skip mark, but now another injector wants to
+//    process the skipped token with another token.  Should you continue
+//    to skip that new token, or reprocess it?  If you reprocess,
+//    you can end up with an infinite loop where one injector converts
+//    <a> to <b>, and then another injector converts it back.  So
+//    we inherit the skips, but for some reason, I thought that we
+//    should inherit the skip from the first token of the token
+//    that we deleted.  Why?  Well, it seems to work OK.
+//
+// If I were to redesign this functionality, I would absolutely not
+// go about doing it this way: the semantics are just not very well
+// defined, and in any case you probably wanted to operate on trees,
+// not token streams.

+ * Chainable filters for custom URI processing.

+ * must have a corresponding configuration directive %URI.Foo,
+ * unless always_load is specified to be true.
+ *
+ * The following contexts may be available while URIFilters are being
+ * processed:
+ *
+ *      - EmbeddedURI: true if URI is an embedded resource that will
+ *        be loaded automatically on page load
+ *      - CurrentToken: a reference to the token that is currently
+ *        being processed
+ *      - CurrentAttr: the name of the attribute that is currently being
+ *        processed
+ *      - CurrentCSSProperty: the name of the CSS property that is
+ *        currently being processed (if applicable)
+ *
+ * @warning This filter is called before scheme object validation occurs.
+ *          Make sure, if you require a specific scheme object, you
+ *          you check that it exists. This allows filters to convert
+ *          proprietary URI schemes into regular ones.

+
+## 6.0.2 - 2015-07-04
+
+* Fixed a memory leak in the curl handlers in which references to callbacks
+  were not being removed by `curl_reset`.
+* Cookies are now extracted properly before redirects.
+* Cookies now allow more character ranges.
+* Decoded Content-Encoding responses are now modified to correctly reflect
+  their state if the encoding was automatically removed by a handler. This
+  means that the `Content-Encoding` header may be removed an the
+  `Content-Length` modified to reflect the message size after removing the
+  encoding.
+* Added a more explicit error message when trying to use `form_params` and
+  `multipart` in the same request.
+* Several fixes for HHVM support.
+* Functions are now conditionally required using an additional level of
+  indirection to help with global Composer installations.
+
+## 6.0.1 - 2015-05-27
+
+* Fixed a bug with serializing the `query` request option where the `&`
+  separator was missing.
+* Added a better error message for when `body` is provided as an array. Please
+  use `form_params` or `multipart` instead.
+* Various doc fixes.
+
+## 6.0.0 - 2015-05-26
+
+* See the UPGRADING.md document for more information.
+* Added `multipart` and `form_params` request options.
+* Added `synchronous` request option.
+* Added the `on_headers` request option.
+* Fixed `expect` handling.
+* No longer adding default middlewares in the client ctor. These need to be
+  present on the provided handler in order to work.
+* Requests are no longer initiated when sending async requests with the
+  CurlMultiHandler. This prevents unexpected recursion from requests completing
+  while ticking the cURL loop.
+* Removed the semantics of setting `default` to `true`. This is no longer
+  required now that the cURL loop is not ticked for async requests.
+* Added request and response logging middleware.
+* No longer allowing self signed certificates when using the StreamHandler.
+* Ensuring that `sink` is valid if saving to a file.
+* Request exceptions now include a "handler context" which provides handler
+  specific contextual information.
+* Added `GuzzleHttp\RequestOptions` to allow request options to be applied
+  using constants.
+* `$maxHandles` has been removed from CurlMultiHandler.
+* `MultipartPostBody` is now part of the `guzzlehttp/psr7` package.
+
+## 5.3.0 - 2015-05-19
+
+* Mock now supports `save_to`
+* Marked `AbstractRequestEvent::getTransaction()` as public.
+* Fixed a bug in which multiple headers using different casing would overwrite
+  previous headers in the associative array.
+* Added `Utils::getDefaultHandler()`
+* Marked `GuzzleHttp\Client::getDefaultUserAgent` as deprecated.
+* URL scheme is now always lowercased.
+
+## 6.0.0-beta.1
+
+* Requires PHP >= 5.5
+* Updated to use PSR-7
+  * Requires immutable messages, which basically means an event based system
+    owned by a request instance is no longer possible.
+  * Utilizing the [Guzzle PSR-7 package](https://github.com/guzzle/psr7).
+  * Removed the dependency on `guzzlehttp/streams`. These stream abstractions
+    are available in the `guzzlehttp/psr7` package under the `GuzzleHttp\Psr7`
+    namespace.
+* Added middleware and handler system
+  * Replaced the Guzzle event and subscriber system with a middleware system.
+  * No longer depends on RingPHP, but rather places the HTTP handlers directly
+    in Guzzle, operating on PSR-7 messages.
+  * Retry logic is now encapsulated in `GuzzleHttp\Middleware::retry`, which
+    means the `guzzlehttp/retry-subscriber` is now obsolete.
+  * Mocking responses is now handled using `GuzzleHttp\Handler\MockHandler`.
+* Asynchronous responses
+  * No longer supports the `future` request option to send an async request.
+    Instead, use one of the `*Async` methods of a client (e.g., `requestAsync`,
+    `getAsync`, etc.).
+  * Utilizing `GuzzleHttp\Promise` instead of React's promise library to avoid
+    recursion required by chaining and forwarding react promises. See
+    https://github.com/guzzle/promises
+  * Added `requestAsync` and `sendAsync` to send request asynchronously.
+  * Added magic methods for `getAsync()`, `postAsync()`, etc. to send requests
+    asynchronously.
+* Request options
+  * POST and form updates
+    * Added the `form_fields` and `form_files` request options.
+    * Removed the `GuzzleHttp\Post` namespace.
+    * The `body` request option no longer accepts an array for POST requests.
+  * The `exceptions` request option has been deprecated in favor of the
+    `http_errors` request options.
+  * The `save_to` request option has been deprecated in favor of `sink` request
+    option.
+* Clients no longer accept an array of URI template string and variables for
+  URI variables. You will need to expand URI templates before passing them
+  into a client constructor or request method.
+* Client methods `get()`, `post()`, `put()`, `patch()`, `options()`, etc. are
+  now magic methods that will send synchronous requests.
+* Replaced `Utils.php` with plain functions in `functions.php`.
+* Removed `GuzzleHttp\Collection`.
+* Removed `GuzzleHttp\BatchResults`. Batched pool results are now returned as
+  an array.
+* Removed `GuzzleHttp\Query`. Query string handling is now handled using an
+  associative array passed into the `query` request option. The query string
+  is serialized using PHP's `http_build_query`. If you need more control, you
+  can pass the query string in as a string.
+* `GuzzleHttp\QueryParser` has been replaced with the
+  `GuzzleHttp\Psr7\parse_query`.
+
+## 5.2.0 - 2015-01-27
+
+* Added `AppliesHeadersInterface` to make applying headers to a request based
+  on the body more generic and not specific to `PostBodyInterface`.
+* Reduced the number of stack frames needed to send requests.
+* Nested futures are now resolved in the client rather than the RequestFsm
+* Finishing state transitions is now handled in the RequestFsm rather than the
+  RingBridge.
+* Added a guard in the Pool class to not use recursion for request retries.
+
+## 5.1.0 - 2014-12-19
+
+* Pool class no longer uses recursion when a request is intercepted.
+* The size of a Pool can now be dynamically adjusted using a callback.
+  See https://github.com/guzzle/guzzle/pull/943.
+* Setting a request option to `null` when creating a request with a client will
+  ensure that the option is not set. This allows you to overwrite default
+  request options on a per-request basis.
+  See https://github.com/guzzle/guzzle/pull/937.
+* Added the ability to limit which protocols are allowed for redirects by
+  specifying a `protocols` array in the `allow_redirects` request option.
+* Nested futures due to retries are now resolved when waiting for synchronous
+  responses. See https://github.com/guzzle/guzzle/pull/947.
+* `"0"` is now an allowed URI path. See
+  https://github.com/guzzle/guzzle/pull/935.
+* `Query` no longer typehints on the `$query` argument in the constructor,
+  allowing for strings and arrays.
+* Exceptions thrown in the `end` event are now correctly wrapped with Guzzle
+  specific exceptions if necessary.
+
+## 5.0.3 - 2014-11-03
+
+This change updates query strings so that they are treated as un-encoded values
+by default where the value represents an un-encoded value to send over the
+wire. A Query object then encodes the value before sending over the wire. This
+means that even value query string values (e.g., ":") are url encoded. This
+makes the Query class match PHP's http_build_query function. However, if you
+want to send requests over the wire using valid query string characters that do
+not need to be encoded, then you can provide a string to Url::setQuery() and
+pass true as the second argument to specify that the query string is a raw
+string that should not be parsed or encoded (unless a call to getQuery() is
+subsequently made, forcing the query-string to be converted into a Query
+object).
+
+## 5.0.2 - 2014-10-30
+
+* Added a trailing `\r\n` to multipart/form-data payloads. See
+  https://github.com/guzzle/guzzle/pull/871
+* Added a `GuzzleHttp\Pool::send()` convenience method to match the docs.
+* Status codes are now returned as integers. See
+  https://github.com/guzzle/guzzle/issues/881
+* No longer overwriting an existing `application/x-www-form-urlencoded` header
+  when sending POST requests, allowing for customized headers. See
+  https://github.com/guzzle/guzzle/issues/877
+* Improved path URL serialization.
+
+  * No longer double percent-encoding characters in the path or query string if
+    they are already encoded.
+  * Now properly encoding the supplied path to a URL object, instead of only
+    encoding ' ' and '?'.
+  * Note: This has been changed in 5.0.3 to now encode query string values by
+    default unless the `rawString` argument is provided when setting the query
+    string on a URL: Now allowing many more characters to be present in the
+    query string without being percent encoded. See https://tools.ietf.org/html/rfc3986#appendix-A
+
+## 5.0.1 - 2014-10-16
+
+Bugfix release.
+
+* Fixed an issue where connection errors still returned response object in
+  error and end events event though the response is unusable. This has been
+  corrected so that a response is not returned in the `getResponse` method of
+  these events if the response did not complete. https://github.com/guzzle/guzzle/issues/867
+* Fixed an issue where transfer statistics were not being populated in the
+  RingBridge. https://github.com/guzzle/guzzle/issues/866
+
+## 5.0.0 - 2014-10-12
+
+Adding support for non-blocking responses and some minor API cleanup.
+
+### New Features
+
+* Added support for non-blocking responses based on `guzzlehttp/guzzle-ring`.
+* Added a public API for creating a default HTTP adapter.
+* Updated the redirect plugin to be non-blocking so that redirects are sent
+  concurrently. Other plugins like this can now be updated to be non-blocking.
+* Added a "progress" event so that you can get upload and download progress
+  events.
+* Added `GuzzleHttp\Pool` which implements FutureInterface and transfers
+  requests concurrently using a capped pool size as efficiently as possible.
+* Added `hasListeners()` to EmitterInterface.
+* Removed `GuzzleHttp\ClientInterface::sendAll` and marked
+  `GuzzleHttp\Client::sendAll` as deprecated (it's still there, just not the
+  recommended way).
+
+### Breaking changes
+
+The breaking changes in this release are relatively minor. The biggest thing to
+look out for is that request and response objects no longer implement fluent
+interfaces.
+
+* Removed the fluent interfaces (i.e., `return $this`) from requests,
+  responses, `GuzzleHttp\Collection`, `GuzzleHttp\Url`,
+  `GuzzleHttp\Query`, `GuzzleHttp\Post\PostBody`, and
+  `GuzzleHttp\Cookie\SetCookie`. This blog post provides a good outline of
+  why I did this: https://ocramius.github.io/blog/fluent-interfaces-are-evil/.
+  This also makes the Guzzle message interfaces compatible with the current
+  PSR-7 message proposal.
+* Removed "functions.php", so that Guzzle is truly PSR-4 compliant. Except
+  for the HTTP request functions from function.php, these functions are now
+  implemented in `GuzzleHttp\Utils` using camelCase. `GuzzleHttp\json_decode`
+  moved to `GuzzleHttp\Utils::jsonDecode`. `GuzzleHttp\get_path` moved to
+  `GuzzleHttp\Utils::getPath`. `GuzzleHttp\set_path` moved to
+  `GuzzleHttp\Utils::setPath`. `GuzzleHttp\batch` should now be
+  `GuzzleHttp\Pool::batch`, which returns an `objectStorage`. Using functions.php
+  caused problems for many users: they aren't PSR-4 compliant, require an
+  explicit include, and needed an if-guard to ensure that the functions are not
+  declared multiple times.
+* Rewrote adapter layer.
+    * Removing all classes from `GuzzleHttp\Adapter`, these are now
+      implemented as callables that are stored in `GuzzleHttp\Ring\Client`.
+    * Removed the concept of "parallel adapters". Sending requests serially or
+      concurrently is now handled using a single adapter.
+    * Moved `GuzzleHttp\Adapter\Transaction` to `GuzzleHttp\Transaction`. The
+      Transaction object now exposes the request, response, and client as public
+      properties. The getters and setters have been removed.
+* Removed the "headers" event. This event was only useful for changing the
+  body a response once the headers of the response were known. You can implement
+  a similar behavior in a number of ways. One example might be to use a
+  FnStream that has access to the transaction being sent. For example, when the
+  first byte is written, you could check if the response headers match your
+  expectations, and if so, change the actual stream body that is being
+  written to.
+* Removed the `asArray` parameter from
+  `GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header
+  value as an array, then use the newly added `getHeaderAsArray()` method of
+  `MessageInterface`. This change makes the Guzzle interfaces compatible with
+  the PSR-7 interfaces.
+* `GuzzleHttp\Message\MessageFactory` no longer allows subclasses to add
+  custom request options using double-dispatch (this was an implementation
+  detail). Instead, you should now provide an associative array to the
+  constructor which is a mapping of the request option name mapping to a
+  function that applies the option value to a request.
+* Removed the concept of "throwImmediately" from exceptions and error events.
+  This control mechanism was used to stop a transfer of concurrent requests
+  from completing. This can now be handled by throwing the exception or by
+  cancelling a pool of requests or each outstanding future request individually.
+* Updated to "GuzzleHttp\Streams" 3.0.
+    * `GuzzleHttp\Stream\StreamInterface::getContents()` no longer accepts a
+      `maxLen` parameter. This update makes the Guzzle streams project
+      compatible with the current PSR-7 proposal.
+    * `GuzzleHttp\Stream\Stream::__construct`,
+      `GuzzleHttp\Stream\Stream::factory`, and
+      `GuzzleHttp\Stream\Utils::create` no longer accept a size in the second
+      argument. They now accept an associative array of options, including the
+      "size" key and "metadata" key which can be used to provide custom metadata.
+
+## 4.2.2 - 2014-09-08
+
+* Fixed a memory leak in the CurlAdapter when reusing cURL handles.
+* No longer using `request_fulluri` in stream adapter proxies.
+* Relative redirects are now based on the last response, not the first response.
+
+## 4.2.1 - 2014-08-19
+
+* Ensuring that the StreamAdapter does not always add a Content-Type header
+* Adding automated github releases with a phar and zip
+
+## 4.2.0 - 2014-08-17
+
+* Now merging in default options using a case-insensitive comparison.
+  Closes https://github.com/guzzle/guzzle/issues/767
+* Added the ability to automatically decode `Content-Encoding` response bodies
+  using the `decode_content` request option. This is set to `true` by default
+  to decode the response body if it comes over the wire with a
+  `Content-Encoding`. Set this value to `false` to disable decoding the
+  response content, and pass a string to provide a request `Accept-Encoding`
+  header and turn on automatic response decoding. This feature now allows you
+  to pass an `Accept-Encoding` header in the headers of a request but still
+  disable automatic response decoding.
+  Closes https://github.com/guzzle/guzzle/issues/764
+* Added the ability to throw an exception immediately when transferring
+  requests in parallel. Closes https://github.com/guzzle/guzzle/issues/760
+* Updating guzzlehttp/streams dependency to ~2.1
+* No longer utilizing the now deprecated namespaced methods from the stream
+  package.
+
+## 4.1.8 - 2014-08-14
+
+* Fixed an issue in the CurlFactory that caused setting the `stream=false`
+  request option to throw an exception.
+  See: https://github.com/guzzle/guzzle/issues/769
+* TransactionIterator now calls rewind on the inner iterator.
+  See: https://github.com/guzzle/guzzle/pull/765
+* You can now set the `Content-Type` header to `multipart/form-data`
+  when creating POST requests to force multipart bodies.
+  See https://github.com/guzzle/guzzle/issues/768
+
+## 4.1.7 - 2014-08-07
+
+* Fixed an error in the HistoryPlugin that caused the same request and response
+  to be logged multiple times when an HTTP protocol error occurs.
+* Ensuring that cURL does not add a default Content-Type when no Content-Type
+  has been supplied by the user. This prevents the adapter layer from modifying
+  the request that is sent over the wire after any listeners may have already
+  put the request in a desired state (e.g., signed the request).
+* Throwing an exception when you attempt to send requests that have the
+  "stream" set to true in parallel using the MultiAdapter.
+* Only calling curl_multi_select when there are active cURL handles. This was
+  previously changed and caused performance problems on some systems due to PHP
+  always selecting until the maximum select timeout.
+* Fixed a bug where multipart/form-data POST fields were not correctly
+  aggregated (e.g., values with "&").
+
+## 4.1.6 - 2014-08-03
+
+* Added helper methods to make it easier to represent messages as strings,
+  including getting the start line and getting headers as a string.
+
+## 4.1.5 - 2014-08-02
+
+* Automatically retrying cURL "Connection died, retrying a fresh connect"
+  errors when possible.
+* cURL implementation cleanup
+* Allowing multiple event subscriber listeners to be registered per event by
+  passing an array of arrays of listener configuration.
+
+## 4.1.4 - 2014-07-22
+
+* Fixed a bug that caused multi-part POST requests with more than one field to
+  serialize incorrectly.
+* Paths can now be set to "0"
+* `ResponseInterface::xml` now accepts a `libxml_options` option and added a
+  missing default argument that was required when parsing XML response bodies.
+* A `save_to` stream is now created lazily, which means that files are not
+  created on disk unless a request succeeds.
+
+## 4.1.3 - 2014-07-15
+
+* Various fixes to multipart/form-data POST uploads
+* Wrapping function.php in an if-statement to ensure Guzzle can be used
+  globally and in a Composer install
+* Fixed an issue with generating and merging in events to an event array
+* POST headers are only applied before sending a request to allow you to change
+  the query aggregator used before uploading
+* Added much more robust query string parsing
+* Fixed various parsing and normalization issues with URLs
+* Fixing an issue where multi-valued headers were not being utilized correctly
+  in the StreamAdapter
+
+## 4.1.2 - 2014-06-18
+
+* Added support for sending payloads with GET requests
+
+## 4.1.1 - 2014-06-08
+
+* Fixed an issue related to using custom message factory options in subclasses
+* Fixed an issue with nested form fields in a multi-part POST
+* Fixed an issue with using the `json` request option for POST requests
+* Added `ToArrayInterface` to `GuzzleHttp\Cookie\CookieJar`
+
+## 4.1.0 - 2014-05-27
+
+* Added a `json` request option to easily serialize JSON payloads.
+* Added a `GuzzleHttp\json_decode()` wrapper to safely parse JSON.
+* Added `setPort()` and `getPort()` to `GuzzleHttp\Message\RequestInterface`.
+* Added the ability to provide an emitter to a client in the client constructor.
+* Added the ability to persist a cookie session using $_SESSION.
+* Added a trait that can be used to add event listeners to an iterator.
+* Removed request method constants from RequestInterface.

+
+## 4.0.0.rc-2 - 2014-03-25
+
+* Removed `getConfig()` and `setConfig()` from clients to avoid confusion
+  around whether things like base_url, message_factory, etc. should be able to
+  be retrieved or modified.
+* Added `getDefaultOption()` and `setDefaultOption()` to ClientInterface
+* functions.php functions were renamed using snake_case to match PHP idioms

+## 3.7.0 - 2013-06-10
+
+* See UPGRADING.md for more information on how to upgrade.
+* Requests now support the ability to specify an array of $options when creating a request to more easily modify a
+  request. You can pass a 'request.options' configuration setting to a client to apply default request options to
+  every request created by a client (e.g. default query string variables, headers, curl options, etc.).
+* Added a static facade class that allows you to use Guzzle with static methods and mount the class to `\Guzzle`.
+  See `Guzzle\Http\StaticClient::mount`.
+* Added `command.request_options` to `Guzzle\Service\Command\AbstractCommand` to pass request options to requests
+      created by a command (e.g. custom headers, query string variables, timeout settings, etc.).
+* Stream size in `Guzzle\Stream\PhpStreamRequestFactory` will now be set if Content-Length is returned in the
+  headers of a response
+* Added `Guzzle\Common\Collection::setPath($path, $value)` to set a value into an array using a nested key
+  (e.g. `$collection->setPath('foo/baz/bar', 'test'); echo $collection['foo']['bar']['bar'];`)
+* ServiceBuilders now support storing and retrieving arbitrary data
+* CachePlugin can now purge all resources for a given URI
+* CachePlugin can automatically purge matching cached items when a non-idempotent request is sent to a resource

+* `Guzzle\Common\Exception\ExceptionCollection` now creates a more readable exception message
+* Fixing BC break: Added back the MonologLogAdapter implementation rather than extending from PsrLog so that older
+  Symfony users can still use the old version of Monolog.
+* Fixing BC break: Added the implementation back in for `Guzzle\Http\Message\AbstractMessage::getTokenizedHeader()`.
+  Now triggering an E_USER_DEPRECATED warning when used. Use `$message->getHeader()->parseParams()`.
+* Several performance improvements to `Guzzle\Common\Collection`
+* Added an `$options` argument to the end of the following methods of `Guzzle\Http\ClientInterface`:
+  createRequest, head, delete, put, patch, post, options, prepareRequest
+* Added an `$options` argument to the end of `Guzzle\Http\Message\Request\RequestFactoryInterface::createRequest()`
+* Added an `applyOptions()` method to `Guzzle\Http\Message\Request\RequestFactoryInterface`
+* Changed `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $body = null)` to
+  `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $options = array())`. You can still pass in a
+  resource, string, or EntityBody into the $options parameter to specify the download location of the response.
+* Changed `Guzzle\Common\Collection::__construct($data)` to no longer accepts a null value for `$data` but a
+  default `array()`
+* Added `Guzzle\Stream\StreamInterface::isRepeatable`
+* Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use
+  $client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or
+  $client->getConfig()->setPath('request.options/headers', array('header_name' => 'value'))`.
+* Removed `Guzzle\Http\ClientInterface::getDefaultHeaders(). Use $client->getConfig()->getPath('request.options/headers')`.

+* Made `Guzzle\Http\Client::expandTemplate` and `getUriTemplate` protected methods.
+* You can now enable E_USER_DEPRECATED warnings to see if you are using a deprecated method by setting
+  `Guzzle\Common\Version::$emitWarnings` to true.
+* Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated. Use
+      `$request->getResponseBody()->isRepeatable()` instead.

+  `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+* Marked `Guzzle\Http\Message\Request::setIsRedirect()` as deprecated. Use the HistoryPlugin instead.
+* Marked `Guzzle\Http\Message\Request::isRedirect()` as deprecated. Use the HistoryPlugin instead.
+* Marked `Guzzle\Cache\CacheAdapterFactory::factory()` as deprecated
+* Marked 'command.headers', 'command.response_body' and 'command.on_complete' as deprecated for AbstractCommand.
+  These will work through Guzzle 4.0
+* Marked 'request.params' for `Guzzle\Http\Client` as deprecated. Use [request.options][params].
+* Marked `Guzzle\Service\Client::enableMagicMethods()` as deprecated. Magic methods can no longer be disabled on a Guzzle\Service\Client.
+* Marked `Guzzle\Service\Client::getDefaultHeaders()` as deprecated. Use $client->getConfig()->getPath('request.options/headers')`.
+* Marked `Guzzle\Service\Client::setDefaultHeaders()` as deprecated. Use $client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`.
+* Marked `Guzzle\Parser\Url\UrlParser` as deprecated. Just use PHP's `parse_url()` and percent encode your UTF-8.
+* Marked `Guzzle\Common\Collection::inject()` as deprecated.

+* CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a
+  CacheStorageInterface. These two objects and interface will be removed in a future version.
+* Always setting X-cache headers on cached responses
+* Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin
+* `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface
+  $request, Response $response);`
+* `CacheStorageInterface::fetch($key)` has changed to `fetch(RequestInterface $request);`
+* `CacheStorageInterface::delete($key)` has changed to `delete(RequestInterface $request);`

+  CanCacheStrategyInterface $canCache = null)`
+* Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)`
+
+## 3.6.0 - 2013-05-29
+
+* ServiceDescription now implements ToArrayInterface
+* Added command.hidden_params to blacklist certain headers from being treated as additionalParameters
+* Guzzle can now correctly parse incomplete URLs
+* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.
+* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution
+* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().
+* Specific header implementations can be created for complex headers. When a message creates a header, it uses a
+  HeaderFactory which can map specific headers to specific header classes. There is now a Link header and
+  CacheControl header implementation.
+* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate
+* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti()
+* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in
+  Guzzle\Http\Curl\RequestMediator
+* Removed the optional $asString parameter from MessageInterface::getHeader(). Just cast the header to a string.
+* Removed the optional $tryChunkedTransfer option from Guzzle\Http\Message\EntityEnclosingRequestInterface
+* Removed the $asObjects argument from Guzzle\Http\Message\MessageInterface::getHeaders()
+* Removed Guzzle\Parser\ParserRegister::get(). Use getParser()
+* Removed Guzzle\Parser\ParserRegister::set(). Use registerParser().
+* All response header helper functions return a string rather than mixing Header objects and strings inconsistently
+* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc. are managed by Guzzle
+  directly via interfaces
+* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist
+  but are a no-op until removed.
+* Most classes that used to require a `Guzzle\Service\Command\CommandInterface` typehint now request a
+  `Guzzle\Service\Command\ArrayCommandInterface`.
+* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
+  on a request while the request is still being transferred
+* The ability to case-insensitively search for header values
+* Guzzle\Http\Message\Header::hasExactHeader
+* Guzzle\Http\Message\Header::raw. Use getAll()
+* Deprecated cache control specific methods on Guzzle\Http\Message\AbstractMessage. Use the CacheControl header object
+  instead.
+* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess
+* Added the ability to cast Model objects to a string to view debug information.
+
+## 3.5.0 - 2013-05-13
+
+* Bug: Fixed a regression so that request responses are parsed only once per oncomplete event rather than multiple times
+* Bug: Better cleanup of one-time events across the board (when an event is meant to fire once, it will now remove
+  itself from the EventDispatcher)
+* Bug: `Guzzle\Log\MessageFormatter` now properly writes "total_time" and "connect_time" values
+* Bug: Cloning an EntityEnclosingRequest now clones the EntityBody too
+* Bug: Fixed an undefined index error when parsing nested JSON responses with a sentAs parameter that reference a
+  non-existent key
+* Bug: All __call() method arguments are now required (helps with mocking frameworks)
+* Deprecating Response::getRequest() and now using a shallow clone of a request object to remove a circular reference
+  to help with refcount based garbage collection of resources created by sending a request
+* Deprecating ZF1 cache and log adapters. These will be removed in the next major version.
+* Deprecating `Response::getPreviousResponse()` (method signature still exists, but it's deprecated). Use the
+  HistoryPlugin for a history.
+* Added a `responseBody` alias for the `response_body` location
+* Refactored internals to no longer rely on Response::getRequest()
+* HistoryPlugin can now be cast to a string
+* HistoryPlugin now logs transactions rather than requests and responses to more accurately keep track of the requests
+  and responses that are sent over the wire
+* Added `getEffectiveUrl()` and `getRedirectCount()` to Response objects
+
+## 3.4.3 - 2013-04-30
+

+* LogPlugin now writes to php://output when STDERR is undefined
+* Added the ability to set multiple POST files for the same key in a single call
+* application/x-www-form-urlencoded POSTs now use the utf-8 charset by default
+* Added the ability to queue CurlExceptions to the MockPlugin
+* Cleaned up how manual responses are queued on requests (removed "queued_response" and now using request.before_send)
+* Configuration loading now allows remote files
+
+## 3.4.1 - 2013-04-16
+
+* Large refactoring to how CurlMulti handles work. There is now a proxy that sits in front of a pool of CurlMulti
+  handles. This greatly simplifies the implementation, fixes a couple bugs, and provides a small performance boost.
+* Exceptions are now properly grouped when sending requests in parallel
+* Redirects are now properly aggregated when a multi transaction fails
+* Redirects now set the response on the original object even in the event of a failure
+* Bug fix: Model names are now properly set even when using $refs
+* Added support for PHP 5.5's CurlFile to prevent warnings with the deprecated @ syntax
+* Added support for oauth_callback in OAuth signatures
+* Added support for oauth_verifier in OAuth signatures
+* Added support to attempt to retrieve a command first literally, then ucfirst, the with inflection
+

+* Bug fix: Fixed "array to string" error when validating a union of types in a service description
+* Bug fix: Removed code that attempted to determine the size of a stream when data is written to the stream
+* Bug fix: Not including an `oauth_token` if the value is null in the OauthPlugin.
+* Bug fix: Now correctly aggregating successful requests and failed requests in CurlMulti when a redirect occurs.
+* The new default CURLOPT_TIMEOUT setting has been increased to 150 seconds so that Guzzle works on poor connections.
+* Added a feature to EntityEnclosingRequest::setBody() that will automatically set the Content-Type of the request if
+  the Content-Type can be determined based on the entity body or the path of the request.
+* Added the ability to overwrite configuration settings in a client when grabbing a throwaway client from a builder.
+* Added support for a PSR-3 LogAdapter.
+* Added a `command.after_prepare` event
+* Added `oauth_callback` parameter to the OauthPlugin
+* Added the ability to create a custom stream class when using a stream factory
+* Added a CachingEntityBody decorator
+* Added support for `additionalParameters` in service descriptions to define how custom parameters are serialized.
+* The bundled SSL certificate is now provided in the phar file and extracted when running Guzzle from a phar.
+* You can now send any EntityEnclosingRequest with POST fields or POST files and cURL will handle creating bodies
+* POST requests using a custom entity body are now treated exactly like PUT requests but with a custom cURL method. This
+  means that the redirect behavior of POST requests with custom bodies will not be the same as POST requests that use
+  POST fields or files (the latter is only used when emulating a form POST in the browser).
+* Lots of cleanup to CurlHandle::factory and RequestFactory::createRequest
+
+## 3.3.1 - 2013-03-10
+
+* Added the ability to create PHP streaming responses from HTTP requests
+* Bug fix: Running any filters when parsing response headers with service descriptions
+* Bug fix: OauthPlugin fixes to allow for multi-dimensional array signing, and sorting parameters before signing

+  response location visitors.
+* Bug fix: Removed the possibility of creating configuration files with circular dependencies
+* RequestFactory::create() now uses the key of a POST file when setting the POST file name

+* Bug fix: Fixed bug in `Guzzle\Http\Message\Response` where wrapping quotes were stripped from `getEtag()`
+* BC: Removed `Guzzle\Http\Utils` class
+* BC: Setting a service description on a client will no longer modify the client's command factories.
+* BC: Emitting IO events from a RequestMediator is now a parameter that must be set in a request's curl options using
+  the 'emit_io' key. This was previously set under a request's parameters using 'curl.emit_io'
+* BC: `Guzzle\Stream\Stream::getWrapper()` and `Guzzle\Stream\Stream::getSteamType()` are no longer converted to
+  lowercase
+* Operation parameter objects are now lazy loaded internally
+* Added ErrorResponsePlugin that can throw errors for responses defined in service description operations' errorResponses
+* Added support for instantiating responseType=class responseClass classes. Classes must implement
+  `Guzzle\Service\Command\ResponseClassInterface`

+  additional properties also support locations and can be used to parse JSON responses where the outermost part of the
+  JSON is an array
+* Added support for nested renaming of JSON models (rename sentAs to name)
+* CachePlugin
+    * Added support for stale-if-error so that the CachePlugin can now serve stale content from the cache on error
+    * Debug headers can now added to cached response in the CachePlugin
+
+## 3.2.0 - 2013-02-14
+
+* CurlMulti is no longer reused globally. A new multi object is created per-client. This helps to isolate clients.
+* URLs with no path no longer contain a "/" by default
+* Guzzle\Http\QueryString does no longer manages the leading "?". This is now handled in Guzzle\Http\Url.
+* BadResponseException no longer includes the full request and response message
+* Adding setData() to Guzzle\Service\Description\ServiceDescriptionInterface

+  aggregation and no longer uses callbacks
+* The URL encoding implementation of Guzzle\Http\QueryString can now be customized
+* Bug fix: Filters were not always invoked for array service description parameters
+* Bug fix: Redirects now use a target response body rather than a temporary response body
+* Bug fix: The default exponential backoff BackoffPlugin was not giving when the request threshold was exceeded

+
+## 3.1.2 - 2013-01-27
+
+* Refactored how operation responses are parsed. Visitors now include a before() method responsible for parsing the
+  response body. For example, the XmlVisitor now parses the XML response into an array in the before() method.
+* Fixed an issue where cURL would not automatically decompress responses when the Accept-Encoding header was sent
+* CURLOPT_SSL_VERIFYHOST is never set to 1 because it is deprecated (see 5e0ff2ef20f839e19d1eeb298f90ba3598784444)
+* Fixed a bug where redirect responses were not chained correctly using getPreviousResponse()
+* Setting default headers on a client after setting the user-agent will not erase the user-agent setting
+
+## 3.1.1 - 2013-01-20
+
+* Adding wildcard support to Guzzle\Common\Collection::getPath()
+* Adding alias support to ServiceBuilder configs
+* Adding Guzzle\Service\Resource\CompositeResourceIteratorFactory and cleaning up factory interface
+

+# Guzzle, PHP HTTP client
+
+[![Latest Version](https://img.shields.io/github/release/guzzle/guzzle.svg?style=flat-square)](https://github.com/guzzle/guzzle/releases)
+[![Build Status](https://img.shields.io/github/workflow/status/guzzle/guzzle/CI?label=ci%20build&style=flat-square)](https://github.com/guzzle/guzzle/actions?query=workflow%3ACI)
+[![Total Downloads](https://img.shields.io/packagist/dt/guzzlehttp/guzzle.svg?style=flat-square)](https://packagist.org/packages/guzzlehttp/guzzle)
+
+Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and
+trivial to integrate with web services.
+
+- Simple interface for building query strings, POST requests, streaming large
+  uploads, streaming large downloads, using HTTP cookies, uploading JSON data,
+  etc...
+- Can send both synchronous and asynchronous requests using the same interface.
+- Uses PSR-7 interfaces for requests, responses, and streams. This allows you
+  to utilize other PSR-7 compatible libraries with Guzzle.
+- Supports PSR-18 allowing interoperability between other PSR-18 HTTP Clients.
+- Abstracts away the underlying HTTP transport, allowing you to write
+  environment and transport agnostic code; i.e., no hard dependency on cURL,
+  PHP streams, sockets, or non-blocking event loops.
+- Middleware system allows you to augment and compose client behavior.
+
+```php
+$client = new \GuzzleHttp\Client();
+$response = $client->request('GET', 'https://api.github.com/repos/guzzle/guzzle');
+
+echo $response->getStatusCode(); // 200
+echo $response->getHeaderLine('content-type'); // 'application/json; charset=utf8'
+echo $response->getBody(); // '{"id": 1420053, "name": "guzzle", ...}'
+
+// Send an asynchronous request.
+$request = new \GuzzleHttp\Psr7\Request('GET', 'http://httpbin.org');
+$promise = $client->sendAsync($request)->then(function ($response) {
+    echo 'I completed! ' . $response->getBody();
+});
+
+$promise->wait();
+```

+Guzzle Upgrade Guide
+====================
+
+6.0 to 7.0
+----------
+
+In order to take advantage of the new features of PHP, Guzzle dropped the support
+of PHP 5. The minimum supported PHP version is now PHP 7.2. Type hints and return
+types for functions and methods have been added wherever possible. 
+
+Please make sure:
+- You are calling a function or a method with the correct type.
+- If you extend a class of Guzzle; update all signatures on methods you override.
+
+#### Other backwards compatibility breaking changes
+
+- Class `GuzzleHttp\UriTemplate` is removed.
+- Class `GuzzleHttp\Exception\SeekException` is removed.
+- Classes `GuzzleHttp\Exception\BadResponseException`, `GuzzleHttp\Exception\ClientException`, 
+  `GuzzleHttp\Exception\ServerException` can no longer be initialized with an empty
+  Response as argument.
+- Class `GuzzleHttp\Exception\ConnectException` now extends `GuzzleHttp\Exception\TransferException`
+  instead of `GuzzleHttp\Exception\RequestException`.
+- Function `GuzzleHttp\Exception\ConnectException::getResponse()` is removed.
+- Function `GuzzleHttp\Exception\ConnectException::hasResponse()` is removed.
+- Constant `GuzzleHttp\ClientInterface::VERSION` is removed. Added `GuzzleHttp\ClientInterface::MAJOR_VERSION` instead.
+- Function `GuzzleHttp\Exception\RequestException::getResponseBodySummary` is removed.
+  Use `\GuzzleHttp\Psr7\get_message_body_summary` as an alternative.
+- Function `GuzzleHttp\Cookie\CookieJar::getCookieValue` is removed.
+- Request option `exception` is removed. Please use `http_errors`.
+- Request option `save_to` is removed. Please use `sink`.
+- Pool option `pool_size` is removed. Please use `concurrency`.
+- We now look for environment variables in the `$_SERVER` super global, due to thread safety issues with `getenv`. We continue to fallback to `getenv` in CLI environments, for maximum compatibility.
+- The `get`, `head`, `put`, `post`, `patch`, `delete`, `getAsync`, `headAsync`, `putAsync`, `postAsync`, `patchAsync`, and `deleteAsync` methods are now implemented as genuine methods on `GuzzleHttp\Client`, with strong typing. The original `__call` implementation remains unchanged for now, for maximum backwards compatibility, but won't be invoked under normal operation.
+- The `log` middleware will log the errors with level `error` instead of `notice` 
+- Support for international domain names (IDN) is now disabled by default, and enabling it requires installing ext-intl, linked against a modern version of the C library (ICU 4.6 or higher).
+
+#### Native functions calls
+
+All internal native functions calls of Guzzle are now prefixed with a slash. This
+change makes it impossible for method overloading by other libraries or applications.
+Example:
+
+```php
+// Before:
+curl_version();
+
+// After:
+\curl_version();
+```
+
+For the full diff you can check [here](https://github.com/guzzle/guzzle/compare/6.5.4..master).
+
+5.0 to 6.0
+----------
+
+Guzzle now uses [PSR-7](https://www.php-fig.org/psr/psr-7/) for HTTP messages.
+Due to the fact that these messages are immutable, this prompted a refactoring
+of Guzzle to use a middleware based system rather than an event system. Any
+HTTP message interaction (e.g., `GuzzleHttp\Message\Request`) need to be
+updated to work with the new immutable PSR-7 request and response objects. Any
+event listeners or subscribers need to be updated to become middleware
+functions that wrap handlers (or are injected into a
+`GuzzleHttp\HandlerStack`).
+
+- Removed `GuzzleHttp\BatchResults`
+- Removed `GuzzleHttp\Collection`
+- Removed `GuzzleHttp\HasDataTrait`
+- Removed `GuzzleHttp\ToArrayInterface`
+- The `guzzlehttp/streams` dependency has been removed. Stream functionality
+  is now present in the `GuzzleHttp\Psr7` namespace provided by the
+  `guzzlehttp/psr7` package.
+- Guzzle no longer uses ReactPHP promises and now uses the
+  `guzzlehttp/promises` library. We use a custom promise library for three
+  significant reasons:
+  1. React promises (at the time of writing this) are recursive. Promise
+     chaining and promise resolution will eventually blow the stack. Guzzle
+     promises are not recursive as they use a sort of trampolining technique.
+     Note: there has been movement in the React project to modify promises to
+     no longer utilize recursion.
+  2. Guzzle needs to have the ability to synchronously block on a promise to
+     wait for a result. Guzzle promises allows this functionality (and does
+     not require the use of recursion).
+  3. Because we need to be able to wait on a result, doing so using React
+     promises requires wrapping react promises with RingPHP futures. This
+     overhead is no longer needed, reducing stack sizes, reducing complexity,
+     and improving performance.
+- `GuzzleHttp\Mimetypes` has been moved to a function in
+  `GuzzleHttp\Psr7\mimetype_from_extension` and
+  `GuzzleHttp\Psr7\mimetype_from_filename`.
+- `GuzzleHttp\Query` and `GuzzleHttp\QueryParser` have been removed. Query
+  strings must now be passed into request objects as strings, or provided to
+  the `query` request option when creating requests with clients. The `query`
+  option uses PHP's `http_build_query` to convert an array to a string. If you
+  need a different serialization technique, you will need to pass the query
+  string in as a string. There are a couple helper functions that will make
+  working with query strings easier: `GuzzleHttp\Psr7\parse_query` and
+  `GuzzleHttp\Psr7\build_query`.
+- Guzzle no longer has a dependency on RingPHP. Due to the use of a middleware
+  system based on PSR-7, using RingPHP and it's middleware system as well adds
+  more complexity than the benefits it provides. All HTTP handlers that were
+  present in RingPHP have been modified to work directly with PSR-7 messages
+  and placed in the `GuzzleHttp\Handler` namespace. This significantly reduces
+  complexity in Guzzle, removes a dependency, and improves performance. RingPHP
+  will be maintained for Guzzle 5 support, but will no longer be a part of
+  Guzzle 6.
+- As Guzzle now uses a middleware based systems the event system and RingPHP
+  integration has been removed. Note: while the event system has been removed,
+  it is possible to add your own type of event system that is powered by the
+  middleware system.
+  - Removed the `Event` namespace.
+  - Removed the `Subscriber` namespace.
+  - Removed `Transaction` class
+  - Removed `RequestFsm`
+  - Removed `RingBridge`
+  - `GuzzleHttp\Subscriber\Cookie` is now provided by
+    `GuzzleHttp\Middleware::cookies`
+  - `GuzzleHttp\Subscriber\HttpError` is now provided by
+    `GuzzleHttp\Middleware::httpError`
+  - `GuzzleHttp\Subscriber\History` is now provided by
+    `GuzzleHttp\Middleware::history`
+  - `GuzzleHttp\Subscriber\Mock` is now provided by
+    `GuzzleHttp\Handler\MockHandler`
+  - `GuzzleHttp\Subscriber\Prepare` is now provided by
+    `GuzzleHttp\PrepareBodyMiddleware`
+  - `GuzzleHttp\Subscriber\Redirect` is now provided by
+    `GuzzleHttp\RedirectMiddleware`
+- Guzzle now uses `Psr\Http\Message\UriInterface` (implements in
+  `GuzzleHttp\Psr7\Uri`) for URI support. `GuzzleHttp\Url` is now gone.
+- Static functions in `GuzzleHttp\Utils` have been moved to namespaced
+  functions under the `GuzzleHttp` namespace. This requires either a Composer
+  based autoloader or you to include functions.php.
+- `GuzzleHttp\ClientInterface::getDefaultOption` has been renamed to
+  `GuzzleHttp\ClientInterface::getConfig`.
+- `GuzzleHttp\ClientInterface::setDefaultOption` has been removed.
+- The `json` and `xml` methods of response objects has been removed. With the
+  migration to strictly adhering to PSR-7 as the interface for Guzzle messages,
+  adding methods to message interfaces would actually require Guzzle messages
+  to extend from PSR-7 messages rather then work with them directly.
+
+## Migrating to middleware
+
+The change to PSR-7 unfortunately required significant refactoring to Guzzle
+due to the fact that PSR-7 messages are immutable. Guzzle 5 relied on an event
+system from plugins. The event system relied on mutability of HTTP messages and
+side effects in order to work. With immutable messages, you have to change your
+workflow to become more about either returning a value (e.g., functional
+middlewares) or setting a value on an object. Guzzle v6 has chosen the
+functional middleware approach.
+
+Instead of using the event system to listen for things like the `before` event,
+you now create a stack based middleware function that intercepts a request on
+the way in and the promise of the response on the way out. This is a much
+simpler and more predictable approach than the event system and works nicely
+with PSR-7 middleware. Due to the use of promises, the middleware system is
+also asynchronous.
+
+v5:
+
+```php
+use GuzzleHttp\Event\BeforeEvent;
+$client = new GuzzleHttp\Client();
+// Get the emitter and listen to the before event.
+$client->getEmitter()->on('before', function (BeforeEvent $e) {
+    // Guzzle v5 events relied on mutation
+    $e->getRequest()->setHeader('X-Foo', 'Bar');
+});
+```
+
+v6:
+
+In v6, you can modify the request before it is sent using the `mapRequest`
+middleware. The idiomatic way in v6 to modify the request/response lifecycle is
+to setup a handler middleware stack up front and inject the handler into a
+client.
+
+```php
+use GuzzleHttp\Middleware;
+// Create a handler stack that has all of the default middlewares attached
+$handler = GuzzleHttp\HandlerStack::create();
+// Push the handler onto the handler stack
+$handler->push(Middleware::mapRequest(function (RequestInterface $request) {
+    // Notice that we have to return a request object
+    return $request->withHeader('X-Foo', 'Bar');
+}));
+// Inject the handler into the client
+$client = new GuzzleHttp\Client(['handler' => $handler]);
+```
+
+## POST Requests
+
+This version added the [`form_params`](http://guzzle.readthedocs.org/en/latest/request-options.html#form_params)
+and `multipart` request options. `form_params` is an associative array of
+strings or array of strings and is used to serialize an
+`application/x-www-form-urlencoded` POST request. The
+[`multipart`](http://guzzle.readthedocs.org/en/latest/request-options.html#multipart)
+option is now used to send a multipart/form-data POST request.
+
+`GuzzleHttp\Post\PostFile` has been removed. Use the `multipart` option to add
+POST files to a multipart/form-data request.
+
+The `body` option no longer accepts an array to send POST requests. Please use
+`multipart` or `form_params` instead.
+
+The `base_url` option has been renamed to `base_uri`.
+
+4.x to 5.0
+----------
+
+## Rewritten Adapter Layer
+
+Guzzle now uses [RingPHP](http://ringphp.readthedocs.org/en/latest) to send
+HTTP requests. The `adapter` option in a `GuzzleHttp\Client` constructor
+is still supported, but it has now been renamed to `handler`. Instead of
+passing a `GuzzleHttp\Adapter\AdapterInterface`, you must now pass a PHP
+`callable` that follows the RingPHP specification.
+
+## Removed Fluent Interfaces
+
+[Fluent interfaces were removed](https://ocramius.github.io/blog/fluent-interfaces-are-evil/)
+from the following classes:
+
+- `GuzzleHttp\Collection`
+- `GuzzleHttp\Url`
+- `GuzzleHttp\Query`
+- `GuzzleHttp\Post\PostBody`
+- `GuzzleHttp\Cookie\SetCookie`
+
+## Removed functions.php
+
+Removed "functions.php", so that Guzzle is truly PSR-4 compliant. The following
+functions can be used as replacements.
+
+- `GuzzleHttp\json_decode` -> `GuzzleHttp\Utils::jsonDecode`
+- `GuzzleHttp\get_path` -> `GuzzleHttp\Utils::getPath`
+- `GuzzleHttp\Utils::setPath` -> `GuzzleHttp\set_path`
+- `GuzzleHttp\Pool::batch` -> `GuzzleHttp\batch`. This function is, however,
+  deprecated in favor of using `GuzzleHttp\Pool::batch()`.
+
+The "procedural" global client has been removed with no replacement (e.g.,
+`GuzzleHttp\get()`, `GuzzleHttp\post()`, etc.). Use a `GuzzleHttp\Client`
+object as a replacement.
+
+## `throwImmediately` has been removed
+
+The concept of "throwImmediately" has been removed from exceptions and error
+events. This control mechanism was used to stop a transfer of concurrent
+requests from completing. This can now be handled by throwing the exception or
+by cancelling a pool of requests or each outstanding future request
+individually.
+
+## headers event has been removed
+
+Removed the "headers" event. This event was only useful for changing the
+body a response once the headers of the response were known. You can implement
+a similar behavior in a number of ways. One example might be to use a
+FnStream that has access to the transaction being sent. For example, when the
+first byte is written, you could check if the response headers match your
+expectations, and if so, change the actual stream body that is being
+written to.
+
+## Updates to HTTP Messages
+
+Removed the `asArray` parameter from
+`GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header
+value as an array, then use the newly added `getHeaderAsArray()` method of
+`MessageInterface`. This change makes the Guzzle interfaces compatible with
+the PSR-7 interfaces.
+
+3.x to 4.0
+----------
+
+## Overarching changes:
+
+- Now requires PHP 5.4 or greater.
+- No longer requires cURL to send requests.
+- Guzzle no longer wraps every exception it throws. Only exceptions that are
+  recoverable are now wrapped by Guzzle.
+- Various namespaces have been removed or renamed.
+- No longer requiring the Symfony EventDispatcher. A custom event dispatcher
+  based on the Symfony EventDispatcher is
+  now utilized in `GuzzleHttp\Event\EmitterInterface` (resulting in significant
+  speed and functionality improvements).
+
+Changes per Guzzle 3.x namespace are described below.
+
+## Batch
+
+The `Guzzle\Batch` namespace has been removed. This is best left to
+third-parties to implement on top of Guzzle's core HTTP library.
+
+## Cache
+
+The `Guzzle\Cache` namespace has been removed. (Todo: No suitable replacement
+has been implemented yet, but hoping to utilize a PSR cache interface).
+
+## Common
+
+- Removed all of the wrapped exceptions. It's better to use the standard PHP
+  library for unrecoverable exceptions.
+- `FromConfigInterface` has been removed.
+- `Guzzle\Common\Version` has been removed. The VERSION constant can be found
+  at `GuzzleHttp\ClientInterface::VERSION`.
+
+### Collection
+
+- `getAll` has been removed. Use `toArray` to convert a collection to an array.
+- `inject` has been removed.
+- `keySearch` has been removed.
+- `getPath` no longer supports wildcard expressions. Use something better like
+  JMESPath for this.
+- `setPath` now supports appending to an existing array via the `[]` notation.
+
+### Events
+
+Guzzle no longer requires Symfony's EventDispatcher component. Guzzle now uses
+`GuzzleHttp\Event\Emitter`.
+
+- `Symfony\Component\EventDispatcher\EventDispatcherInterface` is replaced by
+  `GuzzleHttp\Event\EmitterInterface`.
+- `Symfony\Component\EventDispatcher\EventDispatcher` is replaced by
+  `GuzzleHttp\Event\Emitter`.
+- `Symfony\Component\EventDispatcher\Event` is replaced by
+  `GuzzleHttp\Event\Event`, and Guzzle now has an EventInterface in
+  `GuzzleHttp\Event\EventInterface`.
+- `AbstractHasDispatcher` has moved to a trait, `HasEmitterTrait`, and
+  `HasDispatcherInterface` has moved to `HasEmitterInterface`. Retrieving the
+  event emitter of a request, client, etc. now uses the `getEmitter` method
+  rather than the `getDispatcher` method.
+
+#### Emitter
+
+- Use the `once()` method to add a listener that automatically removes itself
+  the first time it is invoked.
+- Use the `listeners()` method to retrieve a list of event listeners rather than
+  the `getListeners()` method.
+- Use `emit()` instead of `dispatch()` to emit an event from an emitter.
+- Use `attach()` instead of `addSubscriber()` and `detach()` instead of
+  `removeSubscriber()`.
+
+```php
+$mock = new Mock();
+// 3.x
+$request->getEventDispatcher()->addSubscriber($mock);
+$request->getEventDispatcher()->removeSubscriber($mock);
+// 4.x
+$request->getEmitter()->attach($mock);
+$request->getEmitter()->detach($mock);
+```
+
+Use the `on()` method to add a listener rather than the `addListener()` method.
+
+```php
+// 3.x
+$request->getEventDispatcher()->addListener('foo', function (Event $event) { /* ... */ } );
+// 4.x
+$request->getEmitter()->on('foo', function (Event $event, $name) { /* ... */ } );
+```
+
+## Http
+
+### General changes
+
+- The cacert.pem certificate has been moved to `src/cacert.pem`.
+- Added the concept of adapters that are used to transfer requests over the
+  wire.
+- Simplified the event system.
+- Sending requests in parallel is still possible, but batching is no longer a
+  concept of the HTTP layer. Instead, you must use the `complete` and `error`
+  events to asynchronously manage parallel request transfers.
+- `Guzzle\Http\Url` has moved to `GuzzleHttp\Url`.
+- `Guzzle\Http\QueryString` has moved to `GuzzleHttp\Query`.
+- QueryAggregators have been rewritten so that they are simply callable
+  functions.
+- `GuzzleHttp\StaticClient` has been removed. Use the functions provided in
+  `functions.php` for an easy to use static client instance.
+- Exceptions in `GuzzleHttp\Exception` have been updated to all extend from
+  `GuzzleHttp\Exception\TransferException`.
+
+### Client
+
+Calling methods like `get()`, `post()`, `head()`, etc. no longer create and
+return a request, but rather creates a request, sends the request, and returns
+the response.
+
+```php
+// 3.0
+$request = $client->get('/');
+$response = $request->send();
+
+// 4.0
+$response = $client->get('/');
+
+// or, to mirror the previous behavior
+$request = $client->createRequest('GET', '/');
+$response = $client->send($request);
+```
+
+`GuzzleHttp\ClientInterface` has changed.
+
+- The `send` method no longer accepts more than one request. Use `sendAll` to
+  send multiple requests in parallel.
+- `setUserAgent()` has been removed. Use a default request option instead. You
+  could, for example, do something like:
+  `$client->setConfig('defaults/headers/User-Agent', 'Foo/Bar ' . $client::getDefaultUserAgent())`.
+- `setSslVerification()` has been removed. Use default request options instead,
+  like `$client->setConfig('defaults/verify', true)`.
+
+`GuzzleHttp\Client` has changed.
+
+- The constructor now accepts only an associative array. You can include a
+  `base_url` string or array to use a URI template as the base URL of a client.
+  You can also specify a `defaults` key that is an associative array of default
+  request options. You can pass an `adapter` to use a custom adapter,
+  `batch_adapter` to use a custom adapter for sending requests in parallel, or
+  a `message_factory` to change the factory used to create HTTP requests and
+  responses.
+- The client no longer emits a `client.create_request` event.
+- Creating requests with a client no longer automatically utilize a URI
+  template. You must pass an array into a creational method (e.g.,
+  `createRequest`, `get`, `put`, etc.) in order to expand a URI template.
+
+### Messages
+
+Messages no longer have references to their counterparts (i.e., a request no
+longer has a reference to it's response, and a response no loger has a
+reference to its request). This association is now managed through a
+`GuzzleHttp\Adapter\TransactionInterface` object. You can get references to
+these transaction objects using request events that are emitted over the
+lifecycle of a request.
+
+#### Requests with a body
+
+- `GuzzleHttp\Message\EntityEnclosingRequest` and
+  `GuzzleHttp\Message\EntityEnclosingRequestInterface` have been removed. The
+  separation between requests that contain a body and requests that do not
+  contain a body has been removed, and now `GuzzleHttp\Message\RequestInterface`
+  handles both use cases.
+- Any method that previously accepts a `GuzzleHttp\Response` object now accept a
+  `GuzzleHttp\Message\ResponseInterface`.
+- `GuzzleHttp\Message\RequestFactoryInterface` has been renamed to
+  `GuzzleHttp\Message\MessageFactoryInterface`. This interface is used to create
+  both requests and responses and is implemented in
+  `GuzzleHttp\Message\MessageFactory`.
+- POST field and file methods have been removed from the request object. You
+  must now use the methods made available to `GuzzleHttp\Post\PostBodyInterface`
+  to control the format of a POST body. Requests that are created using a
+  standard `GuzzleHttp\Message\MessageFactoryInterface` will automatically use
+  a `GuzzleHttp\Post\PostBody` body if the body was passed as an array or if
+  the method is POST and no body is provided.
+
+```php
+$request = $client->createRequest('POST', '/');
+$request->getBody()->setField('foo', 'bar');
+$request->getBody()->addFile(new PostFile('file_key', fopen('/path/to/content', 'r')));
+```
+
+#### Headers
+
+- `GuzzleHttp\Message\Header` has been removed. Header values are now simply
+  represented by an array of values or as a string. Header values are returned
+  as a string by default when retrieving a header value from a message. You can
+  pass an optional argument of `true` to retrieve a header value as an array
+  of strings instead of a single concatenated string.
+- `GuzzleHttp\PostFile` and `GuzzleHttp\PostFileInterface` have been moved to
+  `GuzzleHttp\Post`. This interface has been simplified and now allows the
+  addition of arbitrary headers.
+- Custom headers like `GuzzleHttp\Message\Header\Link` have been removed. Most
+  of the custom headers are now handled separately in specific
+  subscribers/plugins, and `GuzzleHttp\Message\HeaderValues::parseParams()` has
+  been updated to properly handle headers that contain parameters (like the
+  `Link` header).
+
+#### Responses
+
+- `GuzzleHttp\Message\Response::getInfo()` and
+  `GuzzleHttp\Message\Response::setInfo()` have been removed. Use the event
+  system to retrieve this type of information.
+- `GuzzleHttp\Message\Response::getRawHeaders()` has been removed.
+- `GuzzleHttp\Message\Response::getMessage()` has been removed.
+- `GuzzleHttp\Message\Response::calculateAge()` and other cache specific
+  methods have moved to the CacheSubscriber.
+- Header specific helper functions like `getContentMd5()` have been removed.
+  Just use `getHeader('Content-MD5')` instead.
+- `GuzzleHttp\Message\Response::setRequest()` and
+  `GuzzleHttp\Message\Response::getRequest()` have been removed. Use the event
+  system to work with request and response objects as a transaction.
+- `GuzzleHttp\Message\Response::getRedirectCount()` has been removed. Use the
+  Redirect subscriber instead.
+- `GuzzleHttp\Message\Response::isSuccessful()` and other related methods have
+  been removed. Use `getStatusCode()` instead.
+
+#### Streaming responses
+
+Streaming requests can now be created by a client directly, returning a
+`GuzzleHttp\Message\ResponseInterface` object that contains a body stream
+referencing an open PHP HTTP stream.
+
+```php
+// 3.0
+use Guzzle\Stream\PhpStreamRequestFactory;
+$request = $client->get('/');
+$factory = new PhpStreamRequestFactory();
+$stream = $factory->fromRequest($request);
+$data = $stream->read(1024);
+
+// 4.0
+$response = $client->get('/', ['stream' => true]);
+// Read some data off of the stream in the response body
+$data = $response->getBody()->read(1024);
+```
+
+#### Redirects
+
+The `configureRedirects()` method has been removed in favor of a
+`allow_redirects` request option.
+
+```php
+// Standard redirects with a default of a max of 5 redirects
+$request = $client->createRequest('GET', '/', ['allow_redirects' => true]);
+
+// Strict redirects with a custom number of redirects
+$request = $client->createRequest('GET', '/', [
+    'allow_redirects' => ['max' => 5, 'strict' => true]
+]);
+```
+
+#### EntityBody
+
+EntityBody interfaces and classes have been removed or moved to
+`GuzzleHttp\Stream`. All classes and interfaces that once required
+`GuzzleHttp\EntityBodyInterface` now require
+`GuzzleHttp\Stream\StreamInterface`. Creating a new body for a request no
+longer uses `GuzzleHttp\EntityBody::factory` but now uses
+`GuzzleHttp\Stream\Stream::factory` or even better:
+`GuzzleHttp\Stream\create()`.
+
+- `Guzzle\Http\EntityBodyInterface` is now `GuzzleHttp\Stream\StreamInterface`
+- `Guzzle\Http\EntityBody` is now `GuzzleHttp\Stream\Stream`
+- `Guzzle\Http\CachingEntityBody` is now `GuzzleHttp\Stream\CachingStream`
+- `Guzzle\Http\ReadLimitEntityBody` is now `GuzzleHttp\Stream\LimitStream`
+- `Guzzle\Http\IoEmittyinEntityBody` has been removed.
+
+#### Request lifecycle events
+
+Requests previously submitted a large number of requests. The number of events
+emitted over the lifecycle of a request has been significantly reduced to make
+it easier to understand how to extend the behavior of a request. All events
+emitted during the lifecycle of a request now emit a custom
+`GuzzleHttp\Event\EventInterface` object that contains context providing
+methods and a way in which to modify the transaction at that specific point in
+time (e.g., intercept the request and set a response on the transaction).
+
+- `request.before_send` has been renamed to `before` and now emits a
+  `GuzzleHttp\Event\BeforeEvent`
+- `request.complete` has been renamed to `complete` and now emits a
+  `GuzzleHttp\Event\CompleteEvent`.
+- `request.sent` has been removed. Use `complete`.
+- `request.success` has been removed. Use `complete`.
+- `error` is now an event that emits a `GuzzleHttp\Event\ErrorEvent`.
+- `request.exception` has been removed. Use `error`.
+- `request.receive.status_line` has been removed.
+- `curl.callback.progress` has been removed. Use a custom `StreamInterface` to
+  maintain a status update.
+- `curl.callback.write` has been removed. Use a custom `StreamInterface` to
+  intercept writes.
+- `curl.callback.read` has been removed. Use a custom `StreamInterface` to
+  intercept reads.
+
+`headers` is a new event that is emitted after the response headers of a
+request have been received before the body of the response is downloaded. This
+event emits a `GuzzleHttp\Event\HeadersEvent`.
+
+You can intercept a request and inject a response using the `intercept()` event
+of a `GuzzleHttp\Event\BeforeEvent`, `GuzzleHttp\Event\CompleteEvent`, and
+`GuzzleHttp\Event\ErrorEvent` event.
+
+See: http://docs.guzzlephp.org/en/latest/events.html
+
+## Inflection
+
+The `Guzzle\Inflection` namespace has been removed. This is not a core concern
+of Guzzle.
+
+## Iterator
+
+The `Guzzle\Iterator` namespace has been removed.
+
+- `Guzzle\Iterator\AppendIterator`, `Guzzle\Iterator\ChunkedIterator`, and
+  `Guzzle\Iterator\MethodProxyIterator` are nice, but not a core requirement of
+  Guzzle itself.
+- `Guzzle\Iterator\FilterIterator` is no longer needed because an equivalent
+  class is shipped with PHP 5.4.
+- `Guzzle\Iterator\MapIterator` is not really needed when using PHP 5.5 because
+  it's easier to just wrap an iterator in a generator that maps values.
+
+For a replacement of these iterators, see https://github.com/nikic/iter
+
+## Log
+
+The LogPlugin has moved to https://github.com/guzzle/log-subscriber. The
+`Guzzle\Log` namespace has been removed. Guzzle now relies on
+`Psr\Log\LoggerInterface` for all logging. The MessageFormatter class has been
+moved to `GuzzleHttp\Subscriber\Log\Formatter`.
+
+## Parser
+
+The `Guzzle\Parser` namespace has been removed. This was previously used to
+make it possible to plug in custom parsers for cookies, messages, URI
+templates, and URLs; however, this level of complexity is not needed in Guzzle
+so it has been removed.
+
+- Cookie: Cookie parsing logic has been moved to
+  `GuzzleHttp\Cookie\SetCookie::fromString`.
+- Message: Message parsing logic for both requests and responses has been moved
+  to `GuzzleHttp\Message\MessageFactory::fromMessage`. Message parsing is only
+  used in debugging or deserializing messages, so it doesn't make sense for
+  Guzzle as a library to add this level of complexity to parsing messages.
+- UriTemplate: URI template parsing has been moved to
+  `GuzzleHttp\UriTemplate`. The Guzzle library will automatically use the PECL
+  URI template library if it is installed.
+- Url: URL parsing is now performed in `GuzzleHttp\Url::fromString` (previously
+  it was `Guzzle\Http\Url::factory()`). If custom URL parsing is necessary,
+  then developers are free to subclass `GuzzleHttp\Url`.
+
+## Plugin
+
+The `Guzzle\Plugin` namespace has been renamed to `GuzzleHttp\Subscriber`.
+Several plugins are shipping with the core Guzzle library under this namespace.
+
+- `GuzzleHttp\Subscriber\Cookie`: Replaces the old CookiePlugin. Cookie jar
+  code has moved to `GuzzleHttp\Cookie`.
+- `GuzzleHttp\Subscriber\History`: Replaces the old HistoryPlugin.
+- `GuzzleHttp\Subscriber\HttpError`: Throws errors when a bad HTTP response is
+  received.
+- `GuzzleHttp\Subscriber\Mock`: Replaces the old MockPlugin.
+- `GuzzleHttp\Subscriber\Prepare`: Prepares the body of a request just before
+  sending. This subscriber is attached to all requests by default.
+- `GuzzleHttp\Subscriber\Redirect`: Replaces the RedirectPlugin.
+
+The following plugins have been removed (third-parties are free to re-implement
+these if needed):
+
+- `GuzzleHttp\Plugin\Async` has been removed.
+- `GuzzleHttp\Plugin\CurlAuth` has been removed.
+- `GuzzleHttp\Plugin\ErrorResponse\ErrorResponsePlugin` has been removed. This
+  functionality should instead be implemented with event listeners that occur
+  after normal response parsing occurs in the guzzle/command package.
+
+The following plugins are not part of the core Guzzle package, but are provided
+in separate repositories:
+
+- `Guzzle\Http\Plugin\BackoffPlugin` has been rewritten to be much simpler
+  to build custom retry policies using simple functions rather than various
+  chained classes. See: https://github.com/guzzle/retry-subscriber
+- `Guzzle\Http\Plugin\Cache\CachePlugin` has moved to
+  https://github.com/guzzle/cache-subscriber
+- `Guzzle\Http\Plugin\Log\LogPlugin` has moved to
+  https://github.com/guzzle/log-subscriber
+- `Guzzle\Http\Plugin\Md5\Md5Plugin` has moved to
+  https://github.com/guzzle/message-integrity-subscriber
+- `Guzzle\Http\Plugin\Mock\MockPlugin` has moved to
+  `GuzzleHttp\Subscriber\MockSubscriber`.
+- `Guzzle\Http\Plugin\Oauth\OauthPlugin` has moved to
+  https://github.com/guzzle/oauth-subscriber
+
+## Service
+
+The service description layer of Guzzle has moved into two separate packages:
+
+- http://github.com/guzzle/command Provides a high level abstraction over web
+  services by representing web service operations using commands.
+- http://github.com/guzzle/guzzle-services Provides an implementation of
+  guzzle/command that provides request serialization and response parsing using
+  Guzzle service descriptions.
+
+## Stream
+
+Stream have moved to a separate package available at
+https://github.com/guzzle/streams.
+
+`Guzzle\Stream\StreamInterface` has been given a large update to cleanly take
+on the responsibilities of `Guzzle\Http\EntityBody` and
+`Guzzle\Http\EntityBodyInterface` now that they have been removed. The number
+of methods implemented by the `StreamInterface` has been drastically reduced to
+allow developers to more easily extend and decorate stream behavior.
+
+## Removed methods from StreamInterface
+
+- `getStream` and `setStream` have been removed to better encapsulate streams.
+- `getMetadata` and `setMetadata` have been removed in favor of
+  `GuzzleHttp\Stream\MetadataStreamInterface`.
+- `getWrapper`, `getWrapperData`, `getStreamType`, and `getUri` have all been
+  removed. This data is accessible when
+  using streams that implement `GuzzleHttp\Stream\MetadataStreamInterface`.
+- `rewind` has been removed. Use `seek(0)` for a similar behavior.
+
+## Renamed methods
+
+- `detachStream` has been renamed to `detach`.
+- `feof` has been renamed to `eof`.
+- `ftell` has been renamed to `tell`.
+- `readLine` has moved from an instance method to a static class method of
+  `GuzzleHttp\Stream\Stream`.
+
+## Metadata streams
+
+`GuzzleHttp\Stream\MetadataStreamInterface` has been added to denote streams
+that contain additional metadata accessible via `getMetadata()`.
+`GuzzleHttp\Stream\StreamInterface::getMetadata` and
+`GuzzleHttp\Stream\StreamInterface::setMetadata` have been removed.
+
+## StreamRequestFactory
+
+The entire concept of the StreamRequestFactory has been removed. The way this
+was used in Guzzle 3 broke the actual interface of sending streaming requests
+(instead of getting back a Response, you got a StreamInterface). Streaming
+PHP requests are now implemented through the `GuzzleHttp\Adapter\StreamAdapter`.
+
+3.6 to 3.7
+----------
+
+### Deprecations
+
+- You can now enable E_USER_DEPRECATED warnings to see if you are using any deprecated methods.:
+
+```php
+\Guzzle\Common\Version::$emitWarnings = true;
+```
+
+The following APIs and options have been marked as deprecated:
+
+- Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated. Use `$request->getResponseBody()->isRepeatable()` instead.
+- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+- Marked `Guzzle\Http\Message\Request::setIsRedirect()` as deprecated. Use the HistoryPlugin instead.
+- Marked `Guzzle\Http\Message\Request::isRedirect()` as deprecated. Use the HistoryPlugin instead.
+- Marked `Guzzle\Cache\CacheAdapterFactory::factory()` as deprecated
+- Marked `Guzzle\Service\Client::enableMagicMethods()` as deprecated. Magic methods can no longer be disabled on a Guzzle\Service\Client.
+- Marked `Guzzle\Parser\Url\UrlParser` as deprecated. Just use PHP's `parse_url()` and percent encode your UTF-8.
+- Marked `Guzzle\Common\Collection::inject()` as deprecated.
+- Marked `Guzzle\Plugin\CurlAuth\CurlAuthPlugin` as deprecated. Use
+  `$client->getConfig()->setPath('request.options/auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));` or
+  `$client->setDefaultOption('auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));`
+
+3.7 introduces `request.options` as a parameter for a client configuration and as an optional argument to all creational
+request methods. When paired with a client's configuration settings, these options allow you to specify default settings
+for various aspects of a request. Because these options make other previous configuration options redundant, several
+configuration options and methods of a client and AbstractCommand have been deprecated.
+
+- Marked `Guzzle\Service\Client::getDefaultHeaders()` as deprecated. Use `$client->getDefaultOption('headers')`.
+- Marked `Guzzle\Service\Client::setDefaultHeaders()` as deprecated. Use `$client->setDefaultOption('headers/{header_name}', 'value')`.
+- Marked 'request.params' for `Guzzle\Http\Client` as deprecated. Use `$client->setDefaultOption('params/{param_name}', 'value')`
+- Marked 'command.headers', 'command.response_body' and 'command.on_complete' as deprecated for AbstractCommand. These will work through Guzzle 4.0
+
+        $command = $client->getCommand('foo', array(
+            'command.headers' => array('Test' => '123'),
+            'command.response_body' => '/path/to/file'
+        ));
+
+        // Should be changed to:
+
+        $command = $client->getCommand('foo', array(
+            'command.request_options' => array(
+                'headers' => array('Test' => '123'),
+                'save_as' => '/path/to/file'
+            )
+        ));
+
+### Interface changes
+
+Additions and changes (you will need to update any implementations or subclasses you may have created):
+
+- Added an `$options` argument to the end of the following methods of `Guzzle\Http\ClientInterface`:
+  createRequest, head, delete, put, patch, post, options, prepareRequest
+- Added an `$options` argument to the end of `Guzzle\Http\Message\Request\RequestFactoryInterface::createRequest()`
+- Added an `applyOptions()` method to `Guzzle\Http\Message\Request\RequestFactoryInterface`
+- Changed `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $body = null)` to
+  `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $options = array())`. You can still pass in a
+  resource, string, or EntityBody into the $options parameter to specify the download location of the response.
+- Changed `Guzzle\Common\Collection::__construct($data)` to no longer accepts a null value for `$data` but a
+  default `array()`
+- Added `Guzzle\Stream\StreamInterface::isRepeatable`
+- Made `Guzzle\Http\Client::expandTemplate` and `getUriTemplate` protected methods.
+
+The following methods were removed from interfaces. All of these methods are still available in the concrete classes
+that implement them, but you should update your code to use alternative methods:
+
+- Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use
+  `$client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or
+  `$client->getConfig()->setPath('request.options/headers', array('header_name' => 'value'))` or
+  `$client->setDefaultOption('headers/{header_name}', 'value')`. or
+  `$client->setDefaultOption('headers', array('header_name' => 'value'))`.
+- Removed `Guzzle\Http\ClientInterface::getDefaultHeaders(). Use `$client->getConfig()->getPath('request.options/headers')`.
+- Removed `Guzzle\Http\ClientInterface::expandTemplate()`. This is an implementation detail.
+- Removed `Guzzle\Http\ClientInterface::setRequestFactory()`. This is an implementation detail.
+- Removed `Guzzle\Http\ClientInterface::getCurlMulti()`. This is a very specific implementation detail.
+- Removed `Guzzle\Http\Message\RequestInterface::canCache`. Use the CachePlugin.
+- Removed `Guzzle\Http\Message\RequestInterface::setIsRedirect`. Use the HistoryPlugin.
+- Removed `Guzzle\Http\Message\RequestInterface::isRedirect`. Use the HistoryPlugin.
+
+### Cache plugin breaking changes
+
+- CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a
+  CacheStorageInterface. These two objects and interface will be removed in a future version.
+- Always setting X-cache headers on cached responses
+- Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin
+- `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface
+  $request, Response $response);`
+- `CacheStorageInterface::fetch($key)` has changed to `fetch(RequestInterface $request);`
+- `CacheStorageInterface::delete($key)` has changed to `delete(RequestInterface $request);`
+- Added `CacheStorageInterface::purge($url)`
+- `DefaultRevalidation::__construct(CacheKeyProviderInterface $cacheKey, CacheStorageInterface $cache, CachePlugin
+  $plugin)` has changed to `DefaultRevalidation::__construct(CacheStorageInterface $cache,
+  CanCacheStrategyInterface $canCache = null)`
+- Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)`
+
+3.5 to 3.6
+----------
+
+* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.
+* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution
+* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().
+  For example, setHeader() first removes the header using unset on a HeaderCollection and then calls addHeader().
+  Keeping the Host header and URL host in sync is now handled by overriding the addHeader method in Request.
+* Specific header implementations can be created for complex headers. When a message creates a header, it uses a
+  HeaderFactory which can map specific headers to specific header classes. There is now a Link header and
+  CacheControl header implementation.
+* Moved getLinks() from Response to just be used on a Link header object.
+
+If you previously relied on Guzzle\Http\Message\Header::raw(), then you will need to update your code to use the
+HeaderInterface (e.g. toArray(), getAll(), etc.).
+
+### Interface changes
+
+* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate
+* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti()
+* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in
+  Guzzle\Http\Curl\RequestMediator
+* Removed the optional $asString parameter from MessageInterface::getHeader(). Just cast the header to a string.
+* Removed the optional $tryChunkedTransfer option from Guzzle\Http\Message\EntityEnclosingRequestInterface
+* Removed the $asObjects argument from Guzzle\Http\Message\MessageInterface::getHeaders()
+
+### Removed deprecated functions
+
+* Removed Guzzle\Parser\ParserRegister::get(). Use getParser()
+* Removed Guzzle\Parser\ParserRegister::set(). Use registerParser().
+
+### Deprecations
+
+* The ability to case-insensitively search for header values
+* Guzzle\Http\Message\Header::hasExactHeader
+* Guzzle\Http\Message\Header::raw. Use getAll()
+* Deprecated cache control specific methods on Guzzle\Http\Message\AbstractMessage. Use the CacheControl header object
+  instead.
+
+### Other changes
+
+* All response header helper functions return a string rather than mixing Header objects and strings inconsistently
+* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc. are managed by Guzzle
+  directly via interfaces
+* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist
+  but are a no-op until removed.
+* Most classes that used to require a `Guzzle\Service\Command\CommandInterface` typehint now request a
+  `Guzzle\Service\Command\ArrayCommandInterface`.
+* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
+  on a request while the request is still being transferred
+* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess
+
+3.3 to 3.4
+----------
+
+Base URLs of a client now follow the rules of https://tools.ietf.org/html/rfc3986#section-5.2.2 when merging URLs.
+
+3.2 to 3.3
+----------
+
+### Response::getEtag() quote stripping removed
+
+`Guzzle\Http\Message\Response::getEtag()` no longer strips quotes around the ETag response header
+
+### Removed `Guzzle\Http\Utils`
+
+The `Guzzle\Http\Utils` class was removed. This class was only used for testing.
+
+### Stream wrapper and type
+
+`Guzzle\Stream\Stream::getWrapper()` and `Guzzle\Stream\Stream::getStreamType()` are no longer converted to lowercase.
+
+### curl.emit_io became emit_io
+
+Emitting IO events from a RequestMediator is now a parameter that must be set in a request's curl options using the
+'emit_io' key. This was previously set under a request's parameters using 'curl.emit_io'
+
+3.1 to 3.2
+----------
+
+### CurlMulti is no longer reused globally
+
+Before 3.2, the same CurlMulti object was reused globally for each client. This can cause issue where plugins added
+to a single client can pollute requests dispatched from other clients.
+
+If you still wish to reuse the same CurlMulti object with each client, then you can add a listener to the
+ServiceBuilder's `service_builder.create_client` event to inject a custom CurlMulti object into each client as it is
+created.
+
+```php
+$multi = new Guzzle\Http\Curl\CurlMulti();
+$builder = Guzzle\Service\Builder\ServiceBuilder::factory('/path/to/config.json');
+$builder->addListener('service_builder.create_client', function ($event) use ($multi) {
+    $event['client']->setCurlMulti($multi);
+}
+});
+```
+
+### No default path
+
+URLs no longer have a default path value of '/' if no path was specified.
+
+Before:
+
+```php
+$request = $client->get('http://www.foo.com');
+echo $request->getUrl();
+// >> http://www.foo.com/
+```
+
+After:
+
+```php
+$request = $client->get('http://www.foo.com');
+echo $request->getUrl();
+// >> http://www.foo.com
+```
+
+### Less verbose BadResponseException
+
+The exception message for `Guzzle\Http\Exception\BadResponseException` no longer contains the full HTTP request and
+response information. You can, however, get access to the request and response object by calling `getRequest()` or
+`getResponse()` on the exception object.
+
+### Query parameter aggregation
+
+Multi-valued query parameters are no longer aggregated using a callback function. `Guzzle\Http\Query` now has a
+setAggregator() method that accepts a `Guzzle\Http\QueryAggregator\QueryAggregatorInterface` object. This object is
+responsible for handling the aggregation of multi-valued query string variables into a flattened hash.
+
+2.8 to 3.x
+----------
+
+### Guzzle\Service\Inspector
+
+Change `\Guzzle\Service\Inspector::fromConfig` to `\Guzzle\Common\Collection::fromConfig`
+
+**Before**
+
+```php
+use Guzzle\Service\Inspector;
+
+class YourClient extends \Guzzle\Service\Client
+{
+    public static function factory($config = array())
+    {
+        $default = array();
+        $required = array('base_url', 'username', 'api_key');
+        $config = Inspector::fromConfig($config, $default, $required);
+
+        $client = new self(
+            $config->get('base_url'),
+            $config->get('username'),
+            $config->get('api_key')
+        );
+        $client->setConfig($config);
+
+        $client->setDescription(ServiceDescription::factory(__DIR__ . DIRECTORY_SEPARATOR . 'client.json'));
+
+        return $client;
+    }
+```
+
+**After**
+
+```php
+use Guzzle\Common\Collection;
+
+class YourClient extends \Guzzle\Service\Client
+{
+    public static function factory($config = array())
+    {
+        $default = array();
+        $required = array('base_url', 'username', 'api_key');
+        $config = Collection::fromConfig($config, $default, $required);
+
+        $client = new self(
+            $config->get('base_url'),
+            $config->get('username'),
+            $config->get('api_key')
+        );
+        $client->setConfig($config);
+
+        $client->setDescription(ServiceDescription::factory(__DIR__ . DIRECTORY_SEPARATOR . 'client.json'));
+
+        return $client;

+
+### Guzzle\Common\Inflection\Inflector
+
+Namespace is now `Guzzle\Inflection\Inflector`
+
+### Guzzle\Http\Plugin
+
+Namespace is now `Guzzle\Plugin`. Many other changes occur within this namespace and are detailed in their own sections below.
+
+### Guzzle\Http\Plugin\LogPlugin and Guzzle\Common\Log
+
+Now `Guzzle\Plugin\Log\LogPlugin` and `Guzzle\Log` respectively.
+
+**Before**
+
+```php
+use Guzzle\Common\Log\ClosureLogAdapter;
+use Guzzle\Http\Plugin\LogPlugin;
+
+/** @var \Guzzle\Http\Client */
+$client;
+
+// $verbosity is an integer indicating desired message verbosity level
+$client->addSubscriber(new LogPlugin(new ClosureLogAdapter(function($m) { echo $m; }, $verbosity = LogPlugin::LOG_VERBOSE);
+```
+
+**After**
+
+```php
+use Guzzle\Log\ClosureLogAdapter;
+use Guzzle\Log\MessageFormatter;
+use Guzzle\Plugin\Log\LogPlugin;
+
+/** @var \Guzzle\Http\Client */
+$client;
+
+// $format is a string indicating desired message format -- @see MessageFormatter
+$client->addSubscriber(new LogPlugin(new ClosureLogAdapter(function($m) { echo $m; }, $format = MessageFormatter::DEBUG_FORMAT);
+```
+
+### Guzzle\Http\Plugin\CurlAuthPlugin
+
+Now `Guzzle\Plugin\CurlAuth\CurlAuthPlugin`.
+
+### Guzzle\Http\Plugin\ExponentialBackoffPlugin
+
+Now `Guzzle\Plugin\Backoff\BackoffPlugin`, and other changes.
+
+**Before**
+
+```php
+use Guzzle\Http\Plugin\ExponentialBackoffPlugin;
+
+$backoffPlugin = new ExponentialBackoffPlugin($maxRetries, array_merge(
+        ExponentialBackoffPlugin::getDefaultFailureCodes(), array(429)
+    ));
+
+$client->addSubscriber($backoffPlugin);
+```
+
+**After**
+
+```php
+use Guzzle\Plugin\Backoff\BackoffPlugin;
+use Guzzle\Plugin\Backoff\HttpBackoffStrategy;
+
+// Use convenient factory method instead -- see implementation for ideas of what
+// you can do with chaining backoff strategies
+$backoffPlugin = BackoffPlugin::getExponentialBackoff($maxRetries, array_merge(
+        HttpBackoffStrategy::getDefaultFailureCodes(), array(429)
+    ));
+$client->addSubscriber($backoffPlugin);
+```
+
+### Known Issues
+
+#### [BUG] Accept-Encoding header behavior changed unintentionally.
+
+(See #217) (Fixed in 09daeb8c666fb44499a0646d655a8ae36456575e)
+
+In version 2.8 setting the `Accept-Encoding` header would set the CURLOPT_ENCODING option, which permitted cURL to
+properly handle gzip/deflate compressed responses from the server. In versions affected by this bug this does not happen.
+See issue #217 for a workaround, or use a version containing the fix.

+# Features
+
+- [Promises/A+](https://promisesaplus.com/) implementation.
+- Promise resolution and chaining is handled iteratively, allowing for
+  "infinite" promise chaining.
+- Promises have a synchronous `wait` method.
+- Promises can be cancelled.
+- Works with any object that has a `then` function.
+- C# style async/await coroutine promises using
+  `GuzzleHttp\Promise\Coroutine::of()`.
+
+
+# Quick start
+
+A *promise* represents the eventual result of an asynchronous operation. The
+primary way of interacting with a promise is through its `then` method, which
+registers callbacks to receive either a promise's eventual value or the reason
+why the promise cannot be fulfilled.
+
+
+## Callbacks
+
+Callbacks are registered with the `then` method by providing an optional 
+`$onFulfilled` followed by an optional `$onRejected` function.
+
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise->then(
+    // $onFulfilled
+    function ($value) {
+        echo 'The promise was fulfilled.';
+    },
+    // $onRejected
+    function ($reason) {
+        echo 'The promise was rejected.';
+    }
+);
+```
+
+*Resolving* a promise means that you either fulfill a promise with a *value* or
+reject a promise with a *reason*. Resolving a promises triggers callbacks
+registered with the promises's `then` method. These callbacks are triggered
+only once and in the order in which they were added.
+
+
+## Resolving a promise
+
+Promises are fulfilled using the `resolve($value)` method. Resolving a promise
+with any value other than a `GuzzleHttp\Promise\RejectedPromise` will trigger
+all of the onFulfilled callbacks (resolving a promise with a rejected promise
+will reject the promise and trigger the `$onRejected` callbacks).
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise
+    ->then(function ($value) {
+        // Return a value and don't break the chain
+        return "Hello, " . $value;
+    })
+    // This then is executed after the first then and receives the value
+    // returned from the first then.
+    ->then(function ($value) {
+        echo $value;
+    });
+
+// Resolving the promise triggers the $onFulfilled callbacks and outputs
+// "Hello, reader."
+$promise->resolve('reader.');
+```
+
+
+## Promise forwarding
+
+Promises can be chained one after the other. Each then in the chain is a new
+promise. The return value of a promise is what's forwarded to the next
+promise in the chain. Returning a promise in a `then` callback will cause the
+subsequent promises in the chain to only be fulfilled when the returned promise
+has been fulfilled. The next promise in the chain will be invoked with the
+resolved value of the promise.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$nextPromise = new Promise();
+
+$promise
+    ->then(function ($value) use ($nextPromise) {
+        echo $value;
+        return $nextPromise;
+    })
+    ->then(function ($value) {
+        echo $value;
+    });
+
+// Triggers the first callback and outputs "A"
+$promise->resolve('A');
+// Triggers the second callback and outputs "B"
+$nextPromise->resolve('B');
+```
+
+## Promise rejection
+
+When a promise is rejected, the `$onRejected` callbacks are invoked with the
+rejection reason.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise->then(null, function ($reason) {
+    echo $reason;
+});
+
+$promise->reject('Error!');
+// Outputs "Error!"
+```
+
+## Rejection forwarding
+
+If an exception is thrown in an `$onRejected` callback, subsequent
+`$onRejected` callbacks are invoked with the thrown exception as the reason.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise->then(null, function ($reason) {
+    throw new Exception($reason);
+})->then(null, function ($reason) {
+    assert($reason->getMessage() === 'Error!');
+});
+
+$promise->reject('Error!');
+```
+
+You can also forward a rejection down the promise chain by returning a
+`GuzzleHttp\Promise\RejectedPromise` in either an `$onFulfilled` or
+`$onRejected` callback.
+
+```php
+use GuzzleHttp\Promise\Promise;
+use GuzzleHttp\Promise\RejectedPromise;
+
+$promise = new Promise();
+$promise->then(null, function ($reason) {
+    return new RejectedPromise($reason);
+})->then(null, function ($reason) {
+    assert($reason === 'Error!');
+});
+
+$promise->reject('Error!');
+```
+
+If an exception is not thrown in a `$onRejected` callback and the callback
+does not return a rejected promise, downstream `$onFulfilled` callbacks are
+invoked using the value returned from the `$onRejected` callback.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise
+    ->then(null, function ($reason) {
+        return "It's ok";
+    })
+    ->then(function ($value) {
+        assert($value === "It's ok");
+    });
+
+$promise->reject('Error!');
+```
+
+# Synchronous wait
+
+You can synchronously force promises to complete using a promise's `wait`
+method. When creating a promise, you can provide a wait function that is used
+to synchronously force a promise to complete. When a wait function is invoked
+it is expected to deliver a value to the promise or reject the promise. If the
+wait function does not deliver a value, then an exception is thrown. The wait
+function provided to a promise constructor is invoked when the `wait` function
+of the promise is called.
+
+```php
+$promise = new Promise(function () use (&$promise) {
+    $promise->resolve('foo');
+});
+
+// Calling wait will return the value of the promise.
+echo $promise->wait(); // outputs "foo"
+```
+
+If an exception is encountered while invoking the wait function of a promise,
+the promise is rejected with the exception and the exception is thrown.
+
+```php
+$promise = new Promise(function () use (&$promise) {
+    throw new Exception('foo');
+});
+
+$promise->wait(); // throws the exception.
+```
+
+Calling `wait` on a promise that has been fulfilled will not trigger the wait
+function. It will simply return the previously resolved value.
+
+```php
+$promise = new Promise(function () { die('this is not called!'); });
+$promise->resolve('foo');
+echo $promise->wait(); // outputs "foo"
+```
+
+Calling `wait` on a promise that has been rejected will throw an exception. If
+the rejection reason is an instance of `\Exception` the reason is thrown.
+Otherwise, a `GuzzleHttp\Promise\RejectionException` is thrown and the reason
+can be obtained by calling the `getReason` method of the exception.
+
+```php
+$promise = new Promise();
+$promise->reject('foo');
+$promise->wait();
+```
+
+> PHP Fatal error:  Uncaught exception 'GuzzleHttp\Promise\RejectionException' with message 'The promise was rejected with value: foo'
+
+
+## Unwrapping a promise
+
+When synchronously waiting on a promise, you are joining the state of the
+promise into the current state of execution (i.e., return the value of the
+promise if it was fulfilled or throw an exception if it was rejected). This is
+called "unwrapping" the promise. Waiting on a promise will by default unwrap
+the promise state.
+
+You can force a promise to resolve and *not* unwrap the state of the promise
+by passing `false` to the first argument of the `wait` function:
+
+```php
+$promise = new Promise();
+$promise->reject('foo');
+// This will not throw an exception. It simply ensures the promise has
+// been resolved.
+$promise->wait(false);
+```
+
+When unwrapping a promise, the resolved value of the promise will be waited
+upon until the unwrapped value is not a promise. This means that if you resolve
+promise A with a promise B and unwrap promise A, the value returned by the
+wait function will be the value delivered to promise B.
+
+**Note**: when you do not unwrap the promise, no value is returned.
+
+
+# Cancellation
+
+You can cancel a promise that has not yet been fulfilled using the `cancel()`
+method of a promise. When creating a promise you can provide an optional
+cancel function that when invoked cancels the action of computing a resolution
+of the promise.
+
+
+# API
+
+
+## Promise
+
+When creating a promise object, you can provide an optional `$waitFn` and
+`$cancelFn`. `$waitFn` is a function that is invoked with no arguments and is
+expected to resolve the promise. `$cancelFn` is a function with no arguments
+that is expected to cancel the computation of a promise. It is invoked when the
+`cancel()` method of a promise is called.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise(
+    function () use (&$promise) {
+        $promise->resolve('waited');
+    },
+    function () {
+        // do something that will cancel the promise computation (e.g., close
+        // a socket, cancel a database query, etc...)
+    }
+);
+
+assert('waited' === $promise->wait());
+```
+
+A promise has the following methods:
+
+- `then(callable $onFulfilled, callable $onRejected) : PromiseInterface`
+  
+  Appends fulfillment and rejection handlers to the promise, and returns a new promise resolving to the return value of the called handler.
+
+- `otherwise(callable $onRejected) : PromiseInterface`
+  
+  Appends a rejection handler callback to the promise, and returns a new promise resolving to the return value of the callback if it is called, or to its original fulfillment value if the promise is instead fulfilled.
+
+- `wait($unwrap = true) : mixed`
+
+  Synchronously waits on the promise to complete.
+  
+  `$unwrap` controls whether or not the value of the promise is returned for a
+  fulfilled promise or if an exception is thrown if the promise is rejected.
+  This is set to `true` by default.
+
+- `cancel()`
+
+  Attempts to cancel the promise if possible. The promise being cancelled and
+  the parent most ancestor that has not yet been resolved will also be
+  cancelled. Any promises waiting on the cancelled promise to resolve will also
+  be cancelled.
+
+- `getState() : string`
+
+  Returns the state of the promise. One of `pending`, `fulfilled`, or
+  `rejected`.
+
+- `resolve($value)`
+
+  Fulfills the promise with the given `$value`.
+
+- `reject($reason)`
+
+  Rejects the promise with the given `$reason`.
+
+
+## FulfilledPromise
+
+A fulfilled promise can be created to represent a promise that has been
+fulfilled.
+
+```php
+use GuzzleHttp\Promise\FulfilledPromise;
+
+$promise = new FulfilledPromise('value');
+
+// Fulfilled callbacks are immediately invoked.
+$promise->then(function ($value) {
+    echo $value;
+});
+```
+
+
+## RejectedPromise
+
+A rejected promise can be created to represent a promise that has been
+rejected.
+
+```php
+use GuzzleHttp\Promise\RejectedPromise;
+
+$promise = new RejectedPromise('Error');
+
+// Rejected callbacks are immediately invoked.
+$promise->then(null, function ($reason) {
+    echo $reason;
+});
+```
+
+
+# Promise interop
+
+This library works with foreign promises that have a `then` method. This means
+you can use Guzzle promises with [React promises](https://github.com/reactphp/promise)
+for example. When a foreign promise is returned inside of a then method
+callback, promise resolution will occur recursively.
+
+```php
+// Create a React promise
+$deferred = new React\Promise\Deferred();
+$reactPromise = $deferred->promise();
+
+// Create a Guzzle promise that is fulfilled with a React promise.
+$guzzlePromise = new GuzzleHttp\Promise\Promise();
+$guzzlePromise->then(function ($value) use ($reactPromise) {
+    // Do something something with the value...
+    // Return the React promise
+    return $reactPromise;
+});
+```
+
+Please note that wait and cancel chaining is no longer possible when forwarding
+a foreign promise. You will need to wrap a third-party promise with a Guzzle
+promise in order to utilize wait and cancel functions with foreign promises.
+
+
+## Event Loop Integration
+
+In order to keep the stack size constant, Guzzle promises are resolved
+asynchronously using a task queue. When waiting on promises synchronously, the
+task queue will be automatically run to ensure that the blocking promise and
+any forwarded promises are resolved. When using promises asynchronously in an
+event loop, you will need to run the task queue on each tick of the loop. If
+you do not run the task queue, then promises will not be resolved.
+
+You can run the task queue using the `run()` method of the global task queue
+instance.
+
+```php
+// Get the global task queue
+$queue = GuzzleHttp\Promise\Utils::queue();
+$queue->run();
+```
+
+For example, you could use Guzzle promises with React using a periodic timer:
+
+```php
+$loop = React\EventLoop\Factory::create();
+$loop->addPeriodicTimer(0, [$queue, 'run']);
+```
+
+*TODO*: Perhaps adding a `futureTick()` on each tick would be faster?
+
+
+# Implementation notes
+
+
+## Promise resolution and chaining is handled iteratively
+
+By shuffling pending handlers from one owner to another, promises are
+resolved iteratively, allowing for "infinite" then chaining.
+
+```php
+<?php
+require 'vendor/autoload.php';
+
+use GuzzleHttp\Promise\Promise;
+
+$parent = new Promise();
+$p = $parent;
+
+for ($i = 0; $i < 1000; $i++) {
+    $p = $p->then(function ($v) {
+        // The stack size remains constant (a good thing)
+        echo xdebug_get_stack_depth() . ', ';
+        return $v + 1;
+    });
+}
+
+$parent->resolve(0);
+var_dump($p->wait()); // int(1000)
+
+```
+
+When a promise is fulfilled or rejected with a non-promise value, the promise
+then takes ownership of the handlers of each child promise and delivers values
+down the chain without using recursion.
+
+When a promise is resolved with another promise, the original promise transfers
+all of its pending handlers to the new promise. When the new promise is
+eventually resolved, all of the pending handlers are delivered the forwarded
+value.
+
+
+## A promise is the deferred.
+
+Some promise libraries implement promises using a deferred object to represent
+a computation and a promise object to represent the delivery of the result of
+the computation. This is a nice separation of computation and delivery because
+consumers of the promise cannot modify the value that will be eventually
+delivered.
+
+One side effect of being able to implement promise resolution and chaining
+iteratively is that you need to be able for one promise to reach into the state
+of another promise to shuffle around ownership of handlers. In order to achieve
+this without making the handlers of a promise publicly mutable, a promise is
+also the deferred value, allowing promises of the same parent class to reach
+into and modify the private properties of promises of the same type. While this
+does allow consumers of the value to modify the resolution or rejection of the
+deferred, it is a small price to pay for keeping the stack size constant.
+
+```php
+$promise = new Promise();
+$promise->then(function ($value) { echo $value; });
+// The promise is the deferred value, so you can deliver a value to it.
+$promise->resolve('foo');
+// prints "foo"
+```

+## Upgrading from Function API
+
+A static API was first introduced in 1.4.0, in order to mitigate problems with functions conflicting between global and local copies of the package. The function API will be removed in 2.0.0. A migration table has been provided here for your convenience:
+
+| Original Function | Replacement Method |
+|----------------|----------------|
+| `queue` | `Utils::queue` |
+| `task` | `Utils::task` |
+| `promise_for` | `Create::promiseFor` |
+| `rejection_for` | `Create::rejectionFor` |
+| `exception_for` | `Create::exceptionFor` |
+| `iter_for` | `Create::iterFor` |
+| `inspect` | `Utils::inspect` |
+| `inspect_all` | `Utils::inspectAll` |
+| `unwrap` | `Utils::unwrap` |
+| `all` | `Utils::all` |
+| `some` | `Utils::some` |
+| `any` | `Utils::any` |
+| `settle` | `Utils::settle` |
+| `each` | `Each::of` |
+| `each_limit` | `Each::ofLimit` |
+| `each_limit_all` | `Each::ofLimitAll` |
+| `!is_fulfilled` | `Is::pending` |
+| `is_fulfilled` | `Is::fulfilled` |
+| `is_rejected` | `Is::rejected` |
+| `is_settled` | `Is::settled` |
+| `coroutine` | `Coroutine::of` |

+
+
+## [1.4.2] - 2017-03-20
+
+### Fixed
+
+- Reverted BC break to `Uri::resolve` and `Uri::removeDotSegments` by removing
+  calls to `trigger_error` when deprecated methods are invoked.
+
+
+## [1.4.1] - 2017-02-27
+
+### Added
+
+- Rriggering of silenced deprecation warnings.
+
+### Fixed
+
+- Reverted BC break by reintroducing behavior to automagically fix a URI with a
+  relative path and an authority by adding a leading slash to the path. It's only
+  deprecated now.
+
+
+## [1.4.0] - 2017-02-21
+
+### Added
+
+- Added common URI utility methods based on RFC 3986 (see documentation in the readme):
+  - `Uri::isDefaultPort`
+  - `Uri::isAbsolute`
+  - `Uri::isNetworkPathReference`
+  - `Uri::isAbsolutePathReference`
+  - `Uri::isRelativePathReference`
+  - `Uri::isSameDocumentReference`
+  - `Uri::composeComponents`
+  - `UriNormalizer::normalize`
+  - `UriNormalizer::isEquivalent`
+  - `UriResolver::relativize`
+
+### Changed
+
+- Ensure `ServerRequest::getUriFromGlobals` returns a URI in absolute form.
+- Allow `parse_response` to parse a response without delimiting space and reason.
+- Ensure each URI modification results in a valid URI according to PSR-7 discussions.
+  Invalid modifications will throw an exception instead of returning a wrong URI or
+  doing some magic.
+  - `(new Uri)->withPath('foo')->withHost('example.com')` will throw an exception
+    because the path of a URI with an authority must start with a slash "/" or be empty
+  - `(new Uri())->withScheme('http')` will return `'http://localhost'`
+
+### Deprecated
+
+- `Uri::resolve` in favor of `UriResolver::resolve`
+- `Uri::removeDotSegments` in favor of `UriResolver::removeDotSegments`
+
+### Fixed
+
+- `Stream::read` when length parameter <= 0.
+- `copy_to_stream` reads bytes in chunks instead of `maxLen` into memory.
+- `ServerRequest::getUriFromGlobals` when `Host` header contains port.
+- Compatibility of URIs with `file` scheme and empty host.
+
+
+## [1.3.1] - 2016-06-25
+
+### Fixed
+
+- `Uri::__toString` for network path references, e.g. `//example.org`.
+- Missing lowercase normalization for host.
+- Handling of URI components in case they are `'0'` in a lot of places,
+  e.g. as a user info password.
+- `Uri::withAddedHeader` to correctly merge headers with different case.
+- Trimming of header values in `Uri::withAddedHeader`. Header values may
+  be surrounded by whitespace which should be ignored according to RFC 7230
+  Section 3.2.4. This does not apply to header names.
+- `Uri::withAddedHeader` with an array of header values.
+- `Uri::resolve` when base path has no slash and handling of fragment.
+- Handling of encoding in `Uri::with(out)QueryValue` so one can pass the
+  key/value both in encoded as well as decoded form to those methods. This is
+  consistent with withPath, withQuery etc.
+- `ServerRequest::withoutAttribute` when attribute value is null.
+
+
+## [1.3.0] - 2016-04-13
+
+### Added
+
+- Remaining interfaces needed for full PSR7 compatibility
+  (ServerRequestInterface, UploadedFileInterface, etc.).
+- Support for stream_for from scalars.
+
+### Changed
+
+- Can now extend Uri.
+
+### Fixed
+- A bug in validating request methods by making it more permissive.
+
+
+## [1.2.3] - 2016-02-18
+
+### Fixed
+
+- Support in `GuzzleHttp\Psr7\CachingStream` for seeking forward on remote
+  streams, which can sometimes return fewer bytes than requested with `fread`.
+- Handling of gzipped responses with FNAME headers.
+
+
+## [1.2.2] - 2016-01-22
+
+### Added
+
+- Support for URIs without any authority.
+- Support for HTTP 451 'Unavailable For Legal Reasons.'
+- Support for using '0' as a filename.
+- Support for including non-standard ports in Host headers.
+
+
+## [1.2.1] - 2015-11-02
+
+### Changes
+
+- Now supporting negative offsets when seeking to SEEK_END.
+
+
+## [1.2.0] - 2015-08-15
+
+### Changed
+
+- Body as `"0"` is now properly added to a response.
+- Now allowing forward seeking in CachingStream.
+- Now properly parsing HTTP requests that contain proxy targets in
+  `parse_request`.
+- functions.php is now conditionally required.
+- user-info is no longer dropped when resolving URIs.
+
+
+## [1.1.0] - 2015-06-24
+
+### Changed
+
+- URIs can now be relative.
+- `multipart/form-data` headers are now overridden case-insensitively.
+- URI paths no longer encode the following characters because they are allowed
+  in URIs: "(", ")", "*", "!", "'"
+- A port is no longer added to a URI when the scheme is missing and no port is
+  present.
+
+
+## 1.0.0 - 2015-05-19
+
+Initial release.
+
+Currently unsupported:
+
+- `Psr\Http\Message\ServerRequestInterface`
+- `Psr\Http\Message\UploadedFileInterface`

+# PSR-7 Message Implementation
+
+This repository contains a full [PSR-7](http://www.php-fig.org/psr/psr-7/)
+message implementation, several stream decorators, and some helpful
+functionality like query string parsing.
+
+
+[![Build Status](https://travis-ci.org/guzzle/psr7.svg?branch=master)](https://travis-ci.org/guzzle/psr7)
+
+
+# Stream implementation
+
+This package comes with a number of stream implementations and stream
+decorators.
+
+
+## AppendStream
+
+`GuzzleHttp\Psr7\AppendStream`
+
+Reads from multiple streams, one after the other.
+
+```php
+use GuzzleHttp\Psr7;
+
+$a = Psr7\Utils::streamFor('abc, ');
+$b = Psr7\Utils::streamFor('123.');
+$composed = new Psr7\AppendStream([$a, $b]);
+
+$composed->addStream(Psr7\Utils::streamFor(' Above all listen to me'));
+
+echo $composed; // abc, 123. Above all listen to me.
+```
+
+
+## BufferStream
+
+`GuzzleHttp\Psr7\BufferStream`
+
+Provides a buffer stream that can be written to fill a buffer, and read
+from to remove bytes from the buffer.
+
+This stream returns a "hwm" metadata value that tells upstream consumers
+what the configured high water mark of the stream is, or the maximum
+preferred size of the buffer.
+
+```php
+use GuzzleHttp\Psr7;
+
+// When more than 1024 bytes are in the buffer, it will begin returning
+// false to writes. This is an indication that writers should slow down.
+$buffer = new Psr7\BufferStream(1024);
+```
+
+
+## CachingStream
+
+The CachingStream is used to allow seeking over previously read bytes on
+non-seekable streams. This can be useful when transferring a non-seekable
+entity body fails due to needing to rewind the stream (for example, resulting
+from a redirect). Data that is read from the remote stream will be buffered in
+a PHP temp stream so that previously read bytes are cached first in memory,
+then on disk.
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\Utils::streamFor(fopen('http://www.google.com', 'r'));
+$stream = new Psr7\CachingStream($original);
+
+$stream->read(1024);
+echo $stream->tell();
+// 1024
+
+$stream->seek(0);
+echo $stream->tell();
+// 0
+```
+
+
+## DroppingStream
+
+`GuzzleHttp\Psr7\DroppingStream`
+
+Stream decorator that begins dropping data once the size of the underlying
+stream becomes too full.
+
+```php
+use GuzzleHttp\Psr7;
+
+// Create an empty stream
+$stream = Psr7\Utils::streamFor();
+
+// Start dropping data when the stream has more than 10 bytes
+$dropping = new Psr7\DroppingStream($stream, 10);
+
+$dropping->write('01234567890123456789');
+echo $stream; // 0123456789
+```
+
+
+## FnStream
+
+`GuzzleHttp\Psr7\FnStream`
+
+Compose stream implementations based on a hash of functions.
+
+Allows for easy testing and extension of a provided stream without needing
+to create a concrete class for a simple extension point.
+
+```php
+
+use GuzzleHttp\Psr7;
+
+$stream = Psr7\Utils::streamFor('hi');
+$fnStream = Psr7\FnStream::decorate($stream, [
+    'rewind' => function () use ($stream) {
+        echo 'About to rewind - ';
+        $stream->rewind();
+        echo 'rewound!';
+    }
+]);
+
+$fnStream->rewind();
+// Outputs: About to rewind - rewound!
+```
+
+
+## InflateStream
+
+`GuzzleHttp\Psr7\InflateStream`
+
+Uses PHP's zlib.inflate filter to inflate deflate or gzipped content.
+
+This stream decorator skips the first 10 bytes of the given stream to remove
+the gzip header, converts the provided stream to a PHP stream resource,
+then appends the zlib.inflate filter. The stream is then converted back
+to a Guzzle stream resource to be used as a Guzzle stream.
+
+
+## LazyOpenStream
+
+`GuzzleHttp\Psr7\LazyOpenStream`
+
+Lazily reads or writes to a file that is opened only after an IO operation
+take place on the stream.
+
+```php
+use GuzzleHttp\Psr7;
+
+$stream = new Psr7\LazyOpenStream('/path/to/file', 'r');
+// The file has not yet been opened...
+
+echo $stream->read(10);
+// The file is opened and read from only when needed.
+```
+
+
+## LimitStream
+
+`GuzzleHttp\Psr7\LimitStream`
+
+LimitStream can be used to read a subset or slice of an existing stream object.
+This can be useful for breaking a large file into smaller pieces to be sent in
+chunks (e.g. Amazon S3's multipart upload API).
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\Utils::streamFor(fopen('/tmp/test.txt', 'r+'));
+echo $original->getSize();
+// >>> 1048576
+
+// Limit the size of the body to 1024 bytes and start reading from byte 2048
+$stream = new Psr7\LimitStream($original, 1024, 2048);
+echo $stream->getSize();
+// >>> 1024
+echo $stream->tell();
+// >>> 0
+```
+
+
+## MultipartStream
+
+`GuzzleHttp\Psr7\MultipartStream`
+
+Stream that when read returns bytes for a streaming multipart or
+multipart/form-data stream.
+
+
+## NoSeekStream
+
+`GuzzleHttp\Psr7\NoSeekStream`
+
+NoSeekStream wraps a stream and does not allow seeking.
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\Utils::streamFor('foo');
+$noSeek = new Psr7\NoSeekStream($original);
+
+echo $noSeek->read(3);
+// foo
+var_export($noSeek->isSeekable());
+// false
+$noSeek->seek(0);
+var_export($noSeek->read(3));
+// NULL
+```
+
+
+## PumpStream
+
+`GuzzleHttp\Psr7\PumpStream`
+
+Provides a read only stream that pumps data from a PHP callable.
+
+When invoking the provided callable, the PumpStream will pass the amount of
+data requested to read to the callable. The callable can choose to ignore
+this value and return fewer or more bytes than requested. Any extra data
+returned by the provided callable is buffered internally until drained using
+the read() function of the PumpStream. The provided callable MUST return
+false when there is no more data to read.
+
+
+## Implementing stream decorators
+
+Creating a stream decorator is very easy thanks to the
+`GuzzleHttp\Psr7\StreamDecoratorTrait`. This trait provides methods that
+implement `Psr\Http\Message\StreamInterface` by proxying to an underlying
+stream. Just `use` the `StreamDecoratorTrait` and implement your custom
+methods.
+
+For example, let's say we wanted to call a specific function each time the last
+byte is read from a stream. This could be implemented by overriding the
+`read()` method.
+
+```php
+use Psr\Http\Message\StreamInterface;
+use GuzzleHttp\Psr7\StreamDecoratorTrait;
+
+class EofCallbackStream implements StreamInterface
+{
+    use StreamDecoratorTrait;
+
+    private $callback;
+
+    public function __construct(StreamInterface $stream, callable $cb)
+    {
+        $this->stream = $stream;
+        $this->callback = $cb;
+    }
+
+    public function read($length)
+    {
+        $result = $this->stream->read($length);
+
+        // Invoke the callback when EOF is hit.
+        if ($this->eof()) {
+            call_user_func($this->callback);
+        }
+
+        return $result;
+    }
+}
+```
+
+This decorator could be added to any existing stream and used like so:
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\Utils::streamFor('foo');
+
+$eofStream = new EofCallbackStream($original, function () {
+    echo 'EOF!';
+});
+
+$eofStream->read(2);
+$eofStream->read(1);
+// echoes "EOF!"
+$eofStream->seek(0);
+$eofStream->read(3);
+// echoes "EOF!"
+```
+
+
+## PHP StreamWrapper
+
+You can use the `GuzzleHttp\Psr7\StreamWrapper` class if you need to use a
+PSR-7 stream as a PHP stream resource.
+
+Use the `GuzzleHttp\Psr7\StreamWrapper::getResource()` method to create a PHP
+stream from a PSR-7 stream.
+
+```php
+use GuzzleHttp\Psr7\StreamWrapper;
+
+$stream = GuzzleHttp\Psr7\Utils::streamFor('hello!');
+$resource = StreamWrapper::getResource($stream);
+echo fread($resource, 6); // outputs hello!
+```
+
+
+# Static API
+
+There are various static methods available under the `GuzzleHttp\Psr7` namespace.
+
+
+## `GuzzleHttp\Psr7\Message::toString`
+
+`public static function toString(MessageInterface $message): string`
+
+Returns the string representation of an HTTP message.
+
+```php
+$request = new GuzzleHttp\Psr7\Request('GET', 'http://example.com');
+echo GuzzleHttp\Psr7\Message::toString($request);
+```
+
+
+## `GuzzleHttp\Psr7\Message::bodySummary`
+
+`public static function bodySummary(MessageInterface $message, int $truncateAt = 120): string|null`
+
+Get a short summary of the message body.
+
+Will return `null` if the response is not printable.
+
+
+## `GuzzleHttp\Psr7\Message::rewindBody`
+
+`public static function rewindBody(MessageInterface $message): void`
+
+Attempts to rewind a message body and throws an exception on failure.
+
+The body of the message will only be rewound if a call to `tell()`
+returns a value other than `0`.
+
+
+## `GuzzleHttp\Psr7\Message::parseMessage`
+
+`public static function parseMessage(string $message): array`
+
+Parses an HTTP message into an associative array.
+
+The array contains the "start-line" key containing the start line of
+the message, "headers" key containing an associative array of header
+array values, and a "body" key containing the body of the message.
+
+
+## `GuzzleHttp\Psr7\Message::parseRequestUri`
+
+`public static function parseRequestUri(string $path, array $headers): string`
+
+Constructs a URI for an HTTP request message.
+
+
+## `GuzzleHttp\Psr7\Message::parseRequest`
+
+`public static function parseRequest(string $message): Request`
+
+Parses a request message string into a request object.
+
+
+## `GuzzleHttp\Psr7\Message::parseResponse`
+
+`public static function parseResponse(string $message): Response`
+
+Parses a response message string into a response object.
+
+
+## `GuzzleHttp\Psr7\Header::parse`
+
+`public static function parse(string|array $header): array`
+
+Parse an array of header values containing ";" separated data into an
+array of associative arrays representing the header key value pair data
+of the header. When a parameter does not contain a value, but just
+contains a key, this function will inject a key with a '' string value.
+
+
+## `GuzzleHttp\Psr7\Header::normalize`
+
+`public static function normalize(string|array $header): array`
+
+Converts an array of header values that may contain comma separated
+headers into an array of headers with no comma separated values.
+
+
+## `GuzzleHttp\Psr7\Query::parse`
+
+`public static function parse(string $str, int|bool $urlEncoding = true): array`
+
+Parse a query string into an associative array.
+
+If multiple values are found for the same key, the value of that key
+value pair will become an array. This function does not parse nested
+PHP style arrays into an associative array (e.g., `foo[a]=1&foo[b]=2`
+will be parsed into `['foo[a]' => '1', 'foo[b]' => '2'])`.
+
+
+## `GuzzleHttp\Psr7\Query::build`
+
+`public static function build(array $params, int|false $encoding = PHP_QUERY_RFC3986): string`
+
+Build a query string from an array of key value pairs.
+

+
+## `GuzzleHttp\Psr7\Utils::streamFor`
+
+`public static function streamFor(resource|string|null|int|float|bool|StreamInterface|callable|\Iterator $resource = '', array $options = []): StreamInterface`
+
+Create a new stream based on the input type.
+
+Options is an associative array that can contain the following keys:
+
+- metadata: Array of custom metadata.
+- size: Size of the stream.
+
+This method accepts the following `$resource` types:
+
+- `Psr\Http\Message\StreamInterface`: Returns the value as-is.
+- `string`: Creates a stream object that uses the given string as the contents.
+- `resource`: Creates a stream object that wraps the given PHP stream resource.
+- `Iterator`: If the provided value implements `Iterator`, then a read-only
+  stream object will be created that wraps the given iterable. Each time the
+  stream is read from, data from the iterator will fill a buffer and will be
+  continuously called until the buffer is equal to the requested read size.
+  Subsequent read calls will first read from the buffer and then call `next`
+  on the underlying iterator until it is exhausted.
+- `object` with `__toString()`: If the object has the `__toString()` method,
+  the object will be cast to a string and then a stream will be returned that
+  uses the string value.
+- `NULL`: When `null` is passed, an empty stream object is returned.
+- `callable` When a callable is passed, a read-only stream object will be
+  created that invokes the given callable. The callable is invoked with the
+  number of suggested bytes to read. The callable can return any number of
+  bytes, but MUST return `false` when there is no more data to return. The
+  stream object that wraps the callable will invoke the callable until the
+  number of requested bytes are available. Any additional bytes will be
+  buffered and used in subsequent reads.
+
+```php

+    for ($i = 0; $i < $bytes; $i++) {
+        yield ' ';
+    }
+}
+
+$stream = GuzzleHttp\Psr7\Utils::streamFor($generator(100));
+```
+
+
+## `GuzzleHttp\Psr7\Utils::tryFopen`
+
+`public static function tryFopen(string $filename, string $mode): resource`
+
+Safely opens a PHP stream resource using a filename.
+
+When fopen fails, PHP normally raises a warning. This function adds an
+error handler that checks for errors and throws an exception instead.
+
+
+## `GuzzleHttp\Psr7\Utils::uriFor`
+
+`public static function uriFor(string|UriInterface $uri): UriInterface`
+
+Returns a UriInterface for the given value.
+

+# Additional URI Methods
+
+Aside from the standard `Psr\Http\Message\UriInterface` implementation in form of the `GuzzleHttp\Psr7\Uri` class,
+this library also provides additional functionality when working with URIs as static methods.
+
+## URI Types
+
+An instance of `Psr\Http\Message\UriInterface` can either be an absolute URI or a relative reference.
+An absolute URI has a scheme. A relative reference is used to express a URI relative to another URI,
+the base URI. Relative references can be divided into several forms according to
+[RFC 3986 Section 4.2](https://tools.ietf.org/html/rfc3986#section-4.2):
+
+- network-path references, e.g. `//example.com/path`
+- absolute-path references, e.g. `/path`
+- relative-path references, e.g. `subpath`
+
+The following methods can be used to identify the type of the URI.
+
+### `GuzzleHttp\Psr7\Uri::isAbsolute`
+
+`public static function isAbsolute(UriInterface $uri): bool`
+
+Whether the URI is absolute, i.e. it has a scheme.
+
+### `GuzzleHttp\Psr7\Uri::isNetworkPathReference`
+
+`public static function isNetworkPathReference(UriInterface $uri): bool`
+
+Whether the URI is a network-path reference. A relative reference that begins with two slash characters is
+termed an network-path reference.
+
+### `GuzzleHttp\Psr7\Uri::isAbsolutePathReference`
+
+`public static function isAbsolutePathReference(UriInterface $uri): bool`
+
+Whether the URI is a absolute-path reference. A relative reference that begins with a single slash character is
+termed an absolute-path reference.
+
+### `GuzzleHttp\Psr7\Uri::isRelativePathReference`
+
+`public static function isRelativePathReference(UriInterface $uri): bool`
+
+Whether the URI is a relative-path reference. A relative reference that does not begin with a slash character is
+termed a relative-path reference.
+
+### `GuzzleHttp\Psr7\Uri::isSameDocumentReference`
+
+`public static function isSameDocumentReference(UriInterface $uri, UriInterface $base = null): bool`
+
+Whether the URI is a same-document reference. A same-document reference refers to a URI that is, aside from its
+fragment component, identical to the base URI. When no base URI is given, only an empty URI reference
+(apart from its fragment) is considered a same-document reference.
+
+## URI Components
+
+Additional methods to work with URI components.
+
+### `GuzzleHttp\Psr7\Uri::isDefaultPort`
+
+`public static function isDefaultPort(UriInterface $uri): bool`
+
+Whether the URI has the default port of the current scheme. `Psr\Http\Message\UriInterface::getPort` may return null
+or the standard port. This method can be used independently of the implementation.
+
+### `GuzzleHttp\Psr7\Uri::composeComponents`
+
+`public static function composeComponents($scheme, $authority, $path, $query, $fragment): string`
+
+Composes a URI reference string from its various components according to
+[RFC 3986 Section 5.3](https://tools.ietf.org/html/rfc3986#section-5.3). Usually this method does not need to be called
+manually but instead is used indirectly via `Psr\Http\Message\UriInterface::__toString`.
+
+### `GuzzleHttp\Psr7\Uri::fromParts`
+
+`public static function fromParts(array $parts): UriInterface`
+
+Creates a URI from a hash of [`parse_url`](http://php.net/manual/en/function.parse-url.php) components.
+
+
+### `GuzzleHttp\Psr7\Uri::withQueryValue`
+
+`public static function withQueryValue(UriInterface $uri, $key, $value): UriInterface`
+
+Creates a new URI with a specific query string value. Any existing query string values that exactly match the
+provided key are removed and replaced with the given key value pair. A value of null will set the query string
+key without a value, e.g. "key" instead of "key=value".
+
+### `GuzzleHttp\Psr7\Uri::withQueryValues`
+
+`public static function withQueryValues(UriInterface $uri, array $keyValueArray): UriInterface`
+
+Creates a new URI with multiple query string values. It has the same behavior as `withQueryValue()` but for an
+associative array of key => value.
+
+### `GuzzleHttp\Psr7\Uri::withoutQueryValue`
+
+`public static function withoutQueryValue(UriInterface $uri, $key): UriInterface`
+
+Creates a new URI with a specific query string value removed. Any existing query string values that exactly match the
+provided key are removed.
+
+## Reference Resolution
+
+`GuzzleHttp\Psr7\UriResolver` provides methods to resolve a URI reference in the context of a base URI according
+to [RFC 3986 Section 5](https://tools.ietf.org/html/rfc3986#section-5). This is for example also what web browsers
+do when resolving a link in a website based on the current request URI.
+
+### `GuzzleHttp\Psr7\UriResolver::resolve`
+
+`public static function resolve(UriInterface $base, UriInterface $rel): UriInterface`
+
+Converts the relative URI into a new URI that is resolved against the base URI.
+
+### `GuzzleHttp\Psr7\UriResolver::removeDotSegments`
+
+`public static function removeDotSegments(string $path): string`
+
+Removes dot segments from a path and returns the new path according to
+[RFC 3986 Section 5.2.4](https://tools.ietf.org/html/rfc3986#section-5.2.4).
+
+### `GuzzleHttp\Psr7\UriResolver::relativize`
+
+`public static function relativize(UriInterface $base, UriInterface $target): UriInterface`
+
+Returns the target URI as a relative reference from the base URI. This method is the counterpart to resolve():
+
+```php
+(string) $target === (string) UriResolver::resolve($base, UriResolver::relativize($base, $target))
+```
+
+One use-case is to use the current request URI as base URI and then generate relative links in your documents
+to reduce the document size or offer self-contained downloadable document archives.
+
+```php
+$base = new Uri('http://example.com/a/b/');
+echo UriResolver::relativize($base, new Uri('http://example.com/a/b/c'));  // prints 'c'.
+echo UriResolver::relativize($base, new Uri('http://example.com/a/x/y'));  // prints '../x/y'.
+echo UriResolver::relativize($base, new Uri('http://example.com/a/b/?q')); // prints '?q'.
+echo UriResolver::relativize($base, new Uri('http://example.org/a/b/'));   // prints '//example.org/a/b/'.
+```
+
+## Normalization and Comparison
+
+`GuzzleHttp\Psr7\UriNormalizer` provides methods to normalize and compare URIs according to
+[RFC 3986 Section 6](https://tools.ietf.org/html/rfc3986#section-6).
+
+### `GuzzleHttp\Psr7\UriNormalizer::normalize`
+
+`public static function normalize(UriInterface $uri, $flags = self::PRESERVING_NORMALIZATIONS): UriInterface`
+
+Returns a normalized URI. The scheme and host component are already normalized to lowercase per PSR-7 UriInterface.
+This methods adds additional normalizations that can be configured with the `$flags` parameter which is a bitmask
+of normalizations to apply. The following normalizations are available:
+
+- `UriNormalizer::PRESERVING_NORMALIZATIONS`
+
+    Default normalizations which only include the ones that preserve semantics.
+
+- `UriNormalizer::CAPITALIZE_PERCENT_ENCODING`
+
+    All letters within a percent-encoding triplet (e.g., "%3A") are case-insensitive, and should be capitalized.
+
+    Example: `http://example.org/a%c2%b1b` → `http://example.org/a%C2%B1b`
+
+- `UriNormalizer::DECODE_UNRESERVED_CHARACTERS`
+
+    Decodes percent-encoded octets of unreserved characters. For consistency, percent-encoded octets in the ranges of
+    ALPHA (%41–%5A and %61–%7A), DIGIT (%30–%39), hyphen (%2D), period (%2E), underscore (%5F), or tilde (%7E) should
+    not be created by URI producers and, when found in a URI, should be decoded to their corresponding unreserved
+    characters by URI normalizers.
+
+    Example: `http://example.org/%7Eusern%61me/` → `http://example.org/~username/`
+
+- `UriNormalizer::CONVERT_EMPTY_PATH`
+
+    Converts the empty path to "/" for http and https URIs.
+
+    Example: `http://example.org` → `http://example.org/`
+
+- `UriNormalizer::REMOVE_DEFAULT_HOST`
+
+    Removes the default host of the given URI scheme from the URI. Only the "file" scheme defines the default host
+    "localhost". All of `file:/myfile`, `file:///myfile`, and `file://localhost/myfile` are equivalent according to
+    RFC 3986.
+
+    Example: `file://localhost/myfile` → `file:///myfile`
+
+- `UriNormalizer::REMOVE_DEFAULT_PORT`
+
+    Removes the default port of the given URI scheme from the URI.
+
+    Example: `http://example.org:80/` → `http://example.org/`
+
+- `UriNormalizer::REMOVE_DOT_SEGMENTS`
+
+    Removes unnecessary dot-segments. Dot-segments in relative-path references are not removed as it would
+    change the semantics of the URI reference.
+
+    Example: `http://example.org/../a/b/../c/./d.html` → `http://example.org/a/c/d.html`
+
+- `UriNormalizer::REMOVE_DUPLICATE_SLASHES`
+
+    Paths which include two or more adjacent slashes are converted to one. Webservers usually ignore duplicate slashes
+    and treat those URIs equivalent. But in theory those URIs do not need to be equivalent. So this normalization
+    may change the semantics. Encoded slashes (%2F) are not removed.
+
+    Example: `http://example.org//foo///bar.html` → `http://example.org/foo/bar.html`
+
+- `UriNormalizer::SORT_QUERY_PARAMETERS`
+
+    Sort query parameters with their values in alphabetical order. However, the order of parameters in a URI may be
+    significant (this is not defined by the standard). So this normalization is not safe and may change the semantics
+    of the URI.
+
+    Example: `?lang=en&article=fred` → `?article=fred&lang=en`
+
+### `GuzzleHttp\Psr7\UriNormalizer::isEquivalent`
+
+`public static function isEquivalent(UriInterface $uri1, UriInterface $uri2, $normalizations = self::PRESERVING_NORMALIZATIONS): bool`
+
+Whether two URIs can be considered equivalent. Both URIs are normalized automatically before comparison with the given
+`$normalizations` bitmask. The method also accepts relative URI references and returns true when they are equivalent.
+This of course assumes they will be resolved against the same base URI. If this is not the case, determination of
+equivalence or difference of relative references does not mean anything.

+# Deprecations
+
+This document lists all the planned deprecations.
+
+## Handlers will be removed in 2.0
+
+The `Handler` type and associated calls will be removed in version 2.0.
+
+### Upgrade path
+
+You should create your own implementation for handling OOP usage,
+but it's recommended to move away from using an OOP-style wrapper entirely.
+
+The reason for this is that it's too easy for implementation details (for
+your application this is Flysystem) to leak into the application. The most
+important part for Flysystem is that it improves portability and creates a
+solid boundary between your application core and the infrastructure you use.
+The OOP-style handling breaks this principle, therefore I want to stop
+promoting it.

+A fast and simple streaming zip file downloader for PHP. Using this library will save you from having to write the Zip to disk. You can directly send it to the user, which is much faster. It can work with S3 buckets or any PSR7 Stream.
+
+Please see the [LICENSE](LICENSE) file for licensing and warranty information.
+
+## Installation
+
+Simply add a dependency on maennchen/zipstream-php to your project's composer.json file if you use Composer to manage the dependencies of your project. Use following command to add the package to your project's dependencies:
+
+```bash
+composer require maennchen/zipstream-php
+```
+
+## Usage and options
+
+Here's a simple example:
+
+```php
+// Autoload the dependencies
+require 'vendor/autoload.php';
+
+// enable output of HTTP headers
+$options = new ZipStream\Option\Archive();
+$options->setSendHttpHeaders(true);
+
+// create a new zipstream object
+$zip = new ZipStream\ZipStream('example.zip', $options);
+
+// create a file named 'hello.txt'
+$zip->addFile('hello.txt', 'This is the contents of hello.txt');
+
+// add a file named 'some_image.jpg' from a local file 'path/to/image.jpg'
+$zip->addFileFromPath('some_image.jpg', 'path/to/image.jpg');
+
+// add a file named 'goodbye.txt' from an open stream resource
+$fp = tmpfile();
+fwrite($fp, 'The quick brown fox jumped over the lazy dog.');
+rewind($fp);
+$zip->addFileFromStream('goodbye.txt', $fp);
+fclose($fp);
+
+// finish the zip stream
+$zip->finish();
+```
+
+You can also add comments, modify file timestamps, and customize (or
+disable) the HTTP headers. It is also possible to specify the storage method when adding files,
+the current default storage method is 'deflate' i.e files are stored with Compression mode 0x08.
+
+See the [Wiki](https://github.com/maennchen/ZipStream-PHP/wiki) for details.
+
+## Known issue
+
+The native Mac OS archive extraction tool might not open archives in some conditions. A workaround is to disable the Zip64 feature with the option `$opt->setEnableZip64(false)`. This limits the archive to 4 Gb and 64k files but will allow Mac OS users to open them without issue. See #116.
+
+The linux `unzip` utility might not handle properly unicode characters. It is recommended to extract with another tool like [7-zip](https://www.7-zip.org/). See #146.
+
+## Upgrade to version 2.0.0
+
+* Only the self opened streams will be closed (#139)
+If you were relying on ZipStream to close streams that the library didn't open,
+you'll need to close them yourself now.
+
+## Upgrade to version 1.0.0
+
+* All options parameters to all function have been moved from an `array` to structured option objects. See [the wiki](https://github.com/maennchen/ZipStream-PHP/wiki/Available-options) for examples.
+* The whole library has been refactored. The minimal PHP requirement has been raised to PHP 7.1.
+
+## Usage with Symfony and S3
+
+You can find example code on [the wiki](https://github.com/maennchen/ZipStream-PHP/wiki/Symfony-example).

+/**
+ * ZipStream
+ *
+ * Streamed, dynamically generated zip archives.
+ *
+ * Usage:
+ *
+ * Streaming zip archives is a simple, three-step process:
+ *
+ * 1.  Create the zip stream:
+ *
+ *     $zip = new ZipStream('example.zip');
+ *
+ * 2.  Add one or more files to the archive:
+ *
+ *      * add first file
+ *     $data = file_get_contents('some_file.gif');
+ *     $zip->addFile('some_file.gif', $data);
+ *
+ *      * add second file
+ *     $data = file_get_contents('some_file.gif');
+ *     $zip->addFile('another_file.png', $data);
+ *
+ * 3.  Finish the zip stream:
+ *
+ *     $zip->finish();
+ *
+ * You can also add an archive comment, add comments to individual files,
+ * and adjust the timestamp of files. See the API documentation for each
+ * method below for additional information.
+ *
+ * Example:
+ *
+ *   // create a new zip stream object
+ *   $zip = new ZipStream('some_files.zip');
+ *
+ *   // list of local files
+ *   $files = array('foo.txt', 'bar.jpg');
+ *
+ *   // read and add each file to the archive
+ *   foreach ($files as $path)
+ *     $zip->addFile($path, file_get_contents($path));
+ *
+ *   // write archive footer to stream
+ *   $zip->finish();
+ */

+     * indicates the major version number, and the value
+     * mod 10 is the minor version number.

+     * Large File Support:
+     *
+     * By default, the method addFileFromPath() will send send files
+     * larger than 20 megabytes along raw rather than attempting to
+     * compress them.  You can change both the maximum size and the
+     * compression behavior using the largeFile* options above, with the
+     * following caveats:
+     *
+     * * For "small" files (e.g. files smaller than largeFileSize), the
+     *   memory use can be up to twice that of the actual file.  In other
+     *   words, adding a 10 megabyte file to the archive could potentially
+     *   occupy 20 megabytes of memory.
+     *
+     * * Enabling compression on large files (e.g. files larger than
+     *   large_file_size) is extremely slow, because ZipStream has to pass
+     *   over the large file once to calculate header information, and then
+     *   again to compress and send the actual data.
+     *
+     * Examples:
+     *
+     *   // create a new zip file named 'foo.zip'
+     *   $zip = new ZipStream('foo.zip');
+     *
+     *   // create a new zip file named 'bar.zip' with a comment

+ * negative
+ - inverse (1 / complex)
+ - cos (cosine)
+ - acos (inverse cosine)

+
+# Usage
+
+To create a new complex object, you can provide either the real, imaginary and suffix parts as individual values, or as an array of values passed passed to the constructor; or a string representing the value. e.g
+
+```
+$real = 1.23;
+$imaginary = -4.56;
+$suffix = 'i';
+
+$complexObject = new Complex\Complex($real, $imaginary, $suffix);
+```
+or
+```
+$real = 1.23;
+$imaginary = -4.56;
+$suffix = 'i';
+
+$arguments = [$real, $imaginary, $suffix];
+
+$complexObject = new Complex\Complex($arguments);
+```
+or
+```
+$complexString = '1.23-4.56i';
+
+$complexObject = new Complex\Complex($complexString);
+```
+
+Complex objects are immutable: whenever you call a method or pass a complex value to a function that returns a complex value, a new Complex object will be returned, and the original will remain unchanged.
+This also allows you to chain multiple methods as you would for a fluent interface (as long as they are methods that will return a Complex result).

+To perform mathematical operations with Complex values, you can call the appropriate method against a complex value, passing other values as arguments
+
+```
+$complexString1 = '1.23-4.56i';
+$complexString2 = '2.34+5.67i';
+
+$complexObject = new Complex\Complex($complexString1);
+echo $complexObject->add($complexString2);
+```
+or pass all values to the appropriate function
+```
+$complexString1 = '1.23-4.56i';
+$complexString2 = '2.34+5.67i';
+
+echo Complex\add($complexString1, $complexString2);
+```
+If you want to perform the same operation against multiple values (e.g. to add three or more complex numbers), then you can pass multiple arguments to any of the operations.
+
+You can pass these arguments as Complex objects, or as an array or string that will parse to a complex object.
+
+## Using functions
+
+When calling any of the available functions for a complex value, you can either call the relevant method for the Complex object
+```
+$complexString = '1.23-4.56i';
+
+$complexObject = new Complex\Complex($complexString);
+echo $complexObject->sinh();
+```
+or you can call the function as you would in procedural code, passing the Complex object as an argument 
+```
+$complexString = '1.23-4.56i';
+
+$complexObject = new Complex\Complex($complexString);
+echo Complex\sinh($complexObject);
+```
+When called procedurally using the function, you can pass in the argument as a Complex object, or as an array or string that will parse to a complex object.
+```
+$complexString = '1.23-4.56i';
+
+echo Complex\sinh($complexString);
+```
+
+In the case of the `pow()` function (the only implemented function that requires an additional argument) you need to pass both arguments when calling the function procedurally
+
+```
+$complexString = '1.23-4.56i';
+
+$complexObject = new Complex\Complex($complexString);
+echo Complex\pow($complexObject, 2);
+```
+or pass the additional argument when calling the method
+```
+$complexString = '1.23-4.56i';
+
+$complexObject = new Complex\Complex($complexString);
+echo $complexObject->pow(2);
+```

+
+# Usage
+
+To create a new Matrix object, provide an array as the constructor argument
+
+```php
+$grid = [
+    [16,  3,  2, 13],
+    [ 5, 10, 11,  8],
+    [ 9,  6,  7, 12],
+    [ 4, 15, 14,  1],
+];
+
+$matrix = new Matrix\Matrix($grid);
+```
+The `Builder` class provides helper methods for creating specific matrices, specifically an identity matrix of a specified size; or a matrix of a specified dimensions, with every cell containing a set value.
+```php
+$matrix = Matrix\Builder::createFilledMatrix(1, 5, 3);
+```
+Will create a matrix of 5 rows and 3 columns, filled with a `1` in every cell; while
+```php
+$matrix = Matrix\Builder::createIdentityMatrix(3);
+```
+will create a 3x3 identity matrix.
+
+
+Matrix objects are immutable: whenever you call a method or pass a grid to a function that returns a matrix value, a new Matrix object will be returned, and the original will remain unchanged. This also allows you to chain multiple methods as you would for a fluent interface (as long as they are methods that will return a Matrix result).
+
+## Performing Mathematical Operations
+
+To perform mathematical operations with Matrices, you can call the appropriate method against a matrix value, passing other values as arguments
+
+```php
+$matrix1 = new Matrix\Matrix([
+    [2, 7, 6],
+    [9, 5, 1],
+    [4, 3, 8],
+]);
+$matrix2 = new Matrix\Matrix([
+    [1, 2, 3],
+    [4, 5, 6],
+    [7, 8, 9],
+]);
+
+var_dump($matrix1->multiply($matrix2)->toArray());
+```
+or pass all values to the appropriate function
+```php
+$matrix1 = new Matrix\Matrix([
+    [2, 7, 6],
+    [9, 5, 1],
+    [4, 3, 8],
+]);
+$matrix2 = new Matrix\Matrix([
+    [1, 2, 3],
+    [4, 5, 6],
+    [7, 8, 9],
+]);
+
+var_dump(Matrix\multiply($matrix1, $matrix2)->toArray());
+```
+You can pass in the arguments as Matrix objects, or as arrays.
+
+If you want to perform the same operation against multiple values (e.g. to add three or more matrices), then you can pass multiple arguments to any of the operations.
+
+## Using functions
+
+When calling any of the available functions for a matrix value, you can either call the relevant method for the Matrix object
+```php
+$grid = [
+    [16,  3,  2, 13],
+    [ 5, 10, 11,  8],
+    [ 9,  6,  7, 12],
+    [ 4, 15, 14,  1],
+];
+
+$matrix = new Matrix\Matrix($grid);
+
+echo $matrix->trace();
+```
+or you can call the function as you would in procedural code, passing the Matrix object as an argument 
+```php
+$grid = [
+    [16,  3,  2, 13],
+    [ 5, 10, 11,  8],
+    [ 9,  6,  7, 12],
+    [ 4, 15, 14,  1],
+];
+
+$matrix = new Matrix\Matrix($grid);
+echo Matrix\trace($matrix);
+```
+When called procedurally using the function, you can pass in the argument as a Matrix object, or as an array.
+```php
+$grid = [
+    [16,  3,  2, 13],
+    [ 5, 10, 11,  8],
+    [ 9,  6,  7, 12],
+    [ 4, 15, 14,  1],
+];
+
+echo Matrix\trace($grid);
+```
+As an alternative, it is also possible to call the method directly from the `Functions` class.
+```php
+$grid = [
+    [16,  3,  2, 13],
+    [ 5, 10, 11,  8],
+    [ 9,  6,  7, 12],
+    [ 4, 15, 14,  1],
+];
+
+$matrix = new Matrix\Matrix($grid);
+echo Matrix\Functions::trace($matrix);
+```
+Used this way, methods must be called statically, and the argument must be the Matrix object, and cannot be an array.
+
+## Decomposition
+
+The library also provides classes for matrix decomposition. You can access these using
+```php
+$grid = [
+    [1, 2],
+    [3, 4],
+];
+
+$matrix = new Matrix\Matrix($grid);
+
+$decomposition = new Matrix\Decomposition\QR($matrix);
+$Q = $decomposition->getQ();
+$R = $decomposition->getR();
+```
+
+or alternatively us the `Decomposition` factory, identifying which form of decomposition you want to use
+```php
+$grid = [
+    [1, 2],
+    [3, 4],
+];
+
+$matrix = new Matrix\Matrix($grid);
+
+$decomposition = Matrix\Decomposition\Decomposition::decomposition(Matrix\Decomposition\Decomposition::QR, $matrix);
+$Q = $decomposition->getQ();
+$R = $decomposition->getR();
+```

+* Added support for [JEP-9](https://github.com/jmespath/jmespath.site/blob/master/docs/proposals/improved-filters.rst),
+  including unary filter expressions, and `&&` filter expressions.
+* Fixed various parsing issues, including not removing escaped single quotes
+  from raw string literals.
+* Added support for the `map` function.
+* Fixed several issues with code generation.
+
+## 2.2.0 - 2015-05-27
+
+* Added support for [JEP-12](https://github.com/jmespath/jmespath.site/blob/master/docs/proposals/raw-string-literals.rst)
+  and raw string literals (e.g., `'foo'`).
+
+## 2.1.0 - 2014-01-13
+
+* Added `JmesPath\Env::cleanCompileDir()` to delete any previously compiled
+  JMESPath expressions.
+
+## 2.0.0 - 2014-01-11
+
+* Moving to a flattened namespace structure.
+* Runtimes are now only PHP callables.
+* Fixed an error in the way empty JSON literals are parsed so that they now
+  return an empty string to match the Python and JavaScript implementations.
+* Removed functions from runtimes. Instead there is now a function dispatcher
+  class, FnDispatcher, that provides function implementations behind a single
+  dispatch function.
+* Removed ExprNode in lieu of just using a PHP callable with bound variables.
+* Removed debug methods from runtimes and instead into a new Debugger class.
+* Heavily cleaned up function argument validation.
+* Slice syntax is now properly validated (i.e., colons are followed by the
+  appropriate value).
+* Lots of code cleanup and performance improvements.
+* Added a convenient `JmesPath\search()` function.
+* **IMPORTANT**: Relocating the project to https://github.com/jmespath/jmespath.php
+
+## 1.1.1 - 2014-10-08
+
+* Added support for using ArrayAccess and Countable as arrays and objects.
+
+## 1.1.0 - 2014-08-06
+
+* Added the ability to search data returned from json_decode() where JSON
+  objects are returned as stdClass objects.

+============
+jmespath.php
+============
+
+JMESPath (pronounced "jaymz path") allows you to declaratively specify how to
+extract elements from a JSON document. *jmespath.php* allows you to use
+JMESPath in PHP applications with PHP data structures. It requires PHP 5.4 or
+greater and can be installed through `Composer <http://getcomposer.org/doc/00-intro.md>`_
+using the ``mtdowling/jmespath.php`` package.
+
+.. code-block:: php
+
+    require 'vendor/autoload.php';
+
+    $expression = 'foo.*.baz';
+
+    $data = [
+        'foo' => [
+            'bar' => ['baz' => 1],
+            'bam' => ['baz' => 2],
+            'boo' => ['baz' => 3]
+        ]
+    ];
+
+    JmesPath\search($expression, $data);
+    // Returns: [1, 2, 3]
+
+- `JMESPath Tutorial <http://jmespath.org/tutorial.html>`_
+- `JMESPath Grammar <http://jmespath.org/specification.html#grammar>`_
+- `JMESPath Python library <https://github.com/jmespath/jmespath.py>`_
+
+PHP Usage
+=========
+
+The ``JmesPath\search`` function can be used in most cases when using the
+library. This function utilizes a JMESPath runtime based on your environment.
+The runtime utilized can be configured using environment variables and may at
+some point in the future automatically utilize a C extension if available.
+
+.. code-block:: php
+
+    $result = JmesPath\search($expression, $data);
+
+    // or, if you require PSR-4 compliance.
+    $result = JmesPath\Env::search($expression, $data);
+
+Runtimes
+--------
+
+jmespath.php utilizes *runtimes*. There are currently two runtimes:
+AstRuntime and CompilerRuntime.
+
+AstRuntime is utilized by ``JmesPath\search()`` and ``JmesPath\Env::search()``
+by default.
+
+AstRuntime
+~~~~~~~~~~
+
+The AstRuntime will parse an expression, cache the resulting AST in memory,
+and interpret the AST using an external tree visitor. AstRuntime provides a
+good general approach for interpreting JMESPath expressions that have a low to
+moderate level of reuse.
+
+.. code-block:: php
+
+    $runtime = new JmesPath\AstRuntime();
+    $runtime('foo.bar', ['foo' => ['bar' => 'baz']]);
+    // > 'baz'
+
+CompilerRuntime
+~~~~~~~~~~~~~~~
+
+``JmesPath\CompilerRuntime`` provides the most performance for
+applications that have a moderate to high level of reuse of JMESPath
+expressions. The CompilerRuntime will walk a JMESPath AST and emit PHP source
+code, resulting in anywhere from 7x to 60x speed improvements.
+
+Compiling JMESPath expressions to source code is a slower process than just
+walking and interpreting a JMESPath AST (via the AstRuntime). However,
+running the compiled JMESPath code results in much better performance than
+walking an AST. This essentially means that there is a warm-up period when
+using the ``CompilerRuntime``, but after the warm-up period, it will provide
+much better performance.
+
+Use the CompilerRuntime if you know that you will be executing JMESPath
+expressions more than once or if you can pre-compile JMESPath expressions
+before executing them (for example, server-side applications).
+
+.. code-block:: php
+
+    // Note: The cache directory argument is optional.
+    $runtime = new JmesPath\CompilerRuntime('/path/to/compile/folder');
+    $runtime('foo.bar', ['foo' => ['bar' => 'baz']]);
+    // > 'baz'
+
+Environment Variables
+^^^^^^^^^^^^^^^^^^^^^
+
+You can utilize the CompilerRuntime in ``JmesPath\search()`` by setting
+the ``JP_PHP_COMPILE`` environment variable to "on" or to a directory
+on disk used to store cached expressions.
+
+Testing
+=======
+
+A comprehensive list of test cases can be found at
+https://github.com/jmespath/jmespath.php/tree/master/tests/compliance.
+These compliance tests are utilized by jmespath.php to ensure consistency with
+other implementations, and can serve as examples of the language.
+
+jmespath.php is tested using PHPUnit. In order to run the tests, you need to
+first install the dependencies using Composer as described in the *Installation*
+section. Next you just need to run the tests via make:
+
+.. code-block:: bash
+
+    make test
+
+You can run a suite of performance tests as well:
+
+.. code-block:: bash
+
+    make perf

+# PHP Enum implementation inspired from SplEnum
+
+[![Build Status](https://travis-ci.org/myclabs/php-enum.png?branch=master)](https://travis-ci.org/myclabs/php-enum)
+[![Latest Stable Version](https://poser.pugx.org/myclabs/php-enum/version.png)](https://packagist.org/packages/myclabs/php-enum)
+[![Total Downloads](https://poser.pugx.org/myclabs/php-enum/downloads.png)](https://packagist.org/packages/myclabs/php-enum)
+[![psalm](https://shepherd.dev/github/myclabs/php-enum/coverage.svg)](https://shepherd.dev/github/myclabs/php-enum)
+
+Maintenance for this project is [supported via Tidelift](https://tidelift.com/subscription/pkg/packagist-myclabs-php-enum?utm_source=packagist-myclabs-php-enum&utm_medium=referral&utm_campaign=readme).
+
+## Why?
+
+First, and mainly, `SplEnum` is not integrated to PHP, you have to install the extension separately.
+
+Using an enum instead of class constants provides the following advantages:
+
+- You can use an enum as a parameter type: `function setAction(Action $action) {`
+- You can use an enum as a return type: `function getAction() : Action {`
+- You can enrich the enum with methods (e.g. `format`, `parse`, …)
+- You can extend the enum to add new values (make your enum `final` to prevent it)
+- You can get a list of all the possible values (see below)
+
+This Enum class is not intended to replace class constants, but only to be used when it makes sense.
+
+## Installation
+
+```
+composer require myclabs/php-enum
+```
+
+## Declaration
+
+```php
+use MyCLabs\Enum\Enum;
+
+/**
+ * Action enum
+ */
+final class Action extends Enum
+{
+    private const VIEW = 'view';
+    private const EDIT = 'edit';
+}
+```
+
+## Usage
+
+```php
+$action = Action::VIEW();
+
+// or with a dynamic key:
+$action = Action::$key();
+// or with a dynamic value:
+$action = Action::from($value);
+// or
+$action = new Action($value);
+```
+
+As you can see, static methods are automatically implemented to provide quick access to an enum value.
+
+One advantage over using class constants is to be able to use an enum as a parameter type:
+
+```php
+function setAction(Action $action) {
+    // ...
+}
+```
+
+## Documentation
+
+- `__construct()` The constructor checks that the value exist in the enum
+- `__toString()` You can `echo $myValue`, it will display the enum value (value of the constant)
+- `getValue()` Returns the current value of the enum
+- `getKey()` Returns the key of the current value on Enum
+- `equals()` Tests whether enum instances are equal (returns `true` if enum values are equal, `false` otherwise)
+
+Static methods:
+
+- `from()` Creates an Enum instance, checking that the value exist in the enum
+- `toArray()` method Returns all possible values as an array (constant name in key, constant value in value)
+- `keys()` Returns the names (keys) of all constants in the Enum class
+- `values()` Returns instances of the Enum class of all Enum constants (constant name in key, Enum instance in value)
+- `isValid()` Check if tested value is valid on enum set
+- `isValidKey()` Check if tested key is valid on enum set
+- `assertValidValue()` Assert the value is valid on enum set, throwing exception otherwise
+- `search()` Return key for searched value
+
+### Static methods
+
+```php
+final class Action extends Enum
+{
+    private const VIEW = 'view';
+    private const EDIT = 'edit';
+}
+
+// Static method:
+$action = Action::VIEW();
+$action = Action::EDIT();
+```
+
+Static method helpers are implemented using [`__callStatic()`](http://www.php.net/manual/en/language.oop5.overloading.php#object.callstatic).
+
+If you care about IDE autocompletion, you can either implement the static methods yourself:
+
+```php
+final class Action extends Enum
+{
+    private const VIEW = 'view';
+
+    /**
+     * @return Action
+     */
+    public static function VIEW() {
+        return new Action(self::VIEW);
+    }
+}
+```
+
+or you can use phpdoc (this is supported in PhpStorm for example):
+
+```php
+/**
+ * @method static Action VIEW()
+ * @method static Action EDIT()
+ */
+final class Action extends Enum
+{
+    private const VIEW = 'view';
+    private const EDIT = 'edit';
+}
+```

+CHANGELOG
+---------
+
+### v3.5.5, 2020.06.17
+
+- Fixed a false-positive when using `Opis\Closure\ReflectionClosure::isScopeRequired` method
+
+### v3.5.4, 2020.06.07
+
+- Fixed a false-positive when using `Opis\Closure\ReflectionClosure::isScopeRequired` method
+- Fixed a bug related to `T_STRING_VARNAME`
+
+### v3.5.3, 2020.05.25
+
+- Improved parser
+- The class scope optimisation is no longer used. We always bind now to the closure's original class scope.
+When the class scope was `null`, the optimisation failed to work as expected and kept the wrong `SerializableClosure` scope.
+
+### v3.5.2, 2020.05.21
+
+- Removed extra semicolon in short closures, since is not part of the closure's body.
+
+### v3.5.1, 2019.11.30
+
+- Bugfix. See #47
+
+### v3.5.0, 2019.11.29
+
+- Added support for short closures (arrow functions)
+- Added `isShortClosure` method to `Opis\Closure\ReflectionClosure`
+
+### v3.4.2, 2019.11.29
+
+- Added `stream_set_option()`
+
+### v3.4.1, 2019.10.19
+
+- Fixed a [bug](https://github.com/opis/closure/issues/40) that prevented serialization to work correctly.
+
+### v3.4.0, 2019.09.03
+
+- Added `createClosure` static method in `Opis\Closure\SerializableClosure`.
+This method creates a new closure from arbitrary code, emulating `create_function`,
+but without using eval
+
+### v3.3.1, 2019.07.10
+
+- Use `sha1` instead of `md5` for hashing file names in `Opis\Closure\ReflectionClosure` class
+
+### v3.3.0, 2019.05.31
+
+- Fixed a bug that prevented signed closures to properly work when the serialized string
+contains invalid UTF-8 chars. Starting with this version `json_encode` is no longer used
+when signing a closure. Backward compatibility is maintained and all closures that were 
+previously signed using the old method will continue to work.
+
+### v3.2.0, 2019.05.05
+
+- Since an unsigned closure can be unserialized when no security provider is set, 
+there is no reason to treat differently a signed closure in the same situation.
+Therefore, the `Opis\Closure\SecurityException` exception  is no longer thrown when 
+unserializing a signed closure, if no security provider is set.
+
+### v3.1.6, 2019.02.22
+
+- Fixed a bug that occurred when trying to set properties of classes that were not defined in user-land.
+Those properties are now ignored.
+
+### v3.1.5, 2019.01.14
+
+- Improved parser
+
+### v3.1.4, 2019.01.14
+
+- Added support for static methods that are named using PHP keywords or magic constants.
+Ex: `A::new()`, `A::use()`, `A::if()`, `A::function()`, `A::__DIR__()`, etc.
+- Used `@internal` to mark classes & methods that are for internal use only and
+backward compatibility is not guaranteed.
+
+### v3.1.3, 2019.01.07
+
+- Fixed a bug that prevented traits to be correctly resolved when used by an
+anonymous class
+- Fixed a bug that occurred when `$this` keyword was used inside an anonymous class
+
+### v3.1.2, 2018.12.16
+
+* Fixed a bug regarding comma trail in group-use statements. See [issue 23](https://github.com/opis/closure/issues/23)
+
+### v3.1.1, 2018.10.02
+
+* Fixed a bug where `parent` keyword was treated like a class-name and scope was not added to the
+serialized closure
+* Fixed a bug where return type was not properly handled for nested closures
+* Support for anonymous classes was improved
+
+### v3.1.0, 2018.09.20
+
+* Added `transformUseVariables` and `resolveUseVariables` to
+`Opis\Closure\SerializableClosure` class.
+* Added `removeSecurityProvider` static method to 
+`Opis\Closure\SerializableClosure` class. 
+* Fixed some security related issues where a user was able to unserialize an unsigned
+closure, even when a security provider was in use.
+
+### v3.0.12, 2018.02.23
+
+* Bugfix. See [issue 20](https://github.com/opis/closure/issues/20)
+
+### v3.0.11, 2018.01.22
+
+* Bugfix. See [issue 18](https://github.com/opis/closure/issues/18)
+
+### v3.0.10, 2018.01.04
+
+* Improved support for PHP 7.1 & 7.2
+
+### v3.0.9, 2018.01.04
+
+* Fixed a bug where the return type was not properly resolved. 
+See [issue 17](https://github.com/opis/closure/issues/17)
+* Added more tests
+
+### v3.0.8, 2017.12.18
+
+* Fixed a bug. See [issue 16](https://github.com/opis/closure/issues/16)
+
+### v3.0.7, 2017.10.31
+
+* Bugfix: static properties are ignored now, since they are not serializable
+
+### v3.0.6, 2017.10.06

+Serializable closures
+---------------------
+**Opis Closure** is a library that aims to overcome PHP's limitations regarding closure
+serialization by providing a wrapper that will make all closures serializable. 
+
+**The library's key features:**
+
+- Serialize any closure
+- Serialize arbitrary objects
+- Doesn't use `eval` for closure serialization or unserialization
+- Works with any PHP version that has support for closures
+- Supports PHP 7 syntax
+- Handles all variables referenced/imported in `use()` and automatically wraps all referenced/imported closures for
+proper serialization
+- Handles recursive closures
+- Handles magic constants like `__FILE__`, `__DIR__`, `__LINE__`, `__NAMESPACE__`, `__CLASS__`,
+`__TRAIT__`, `__METHOD__` and `__FUNCTION__`.
+- Automatically resolves all class names, function names and constant names used inside the closure
+- Track closure's residing source by using the `#trackme` directive
+- Simple and very fast parser
+- Any error or exception, that might occur when executing an unserialized closure, can be caught and treated properly
+- You can serialize/unserialize any closure unlimited times, even those previously unserialized
+(this is possible because `eval()` is not used for unserialization)
+- Handles static closures
+- Supports cryptographically signed closures
+- Provides a reflector that can give you information about the serialized closure
+- Provides an analyzer for *SuperClosure* library
+- Automatically detects when the scope and/or the bound object of a closure needs to be serialized
+in order for the closure to work after deserialization

+## Requirements
+
+* PHP ^5.4 || ^7.0
+
+## Installation
+
+**Opis Closure** is available on [Packagist] and it can be installed from a 
+command line interface by using [Composer]. 
+
+```bash
+composer require opis/closure
+```
+
+Or you could directly reference it into your `composer.json` file as a dependency
+
+```json
+{
+    "require": {
+        "opis/closure": "^3.5"
+    }
+}
+```
+
+### Migrating from 2.x
+
+If your project needs to support PHP 5.3 you can continue using the `2.x` version
+of **Opis Closure**. Otherwise, assuming you are not using one of the removed/refactored classes or features(see 
+[CHANGELOG]), migrating to version `3.x` is simply a matter of updating your `composer.json` file. 
+
+### Semantic versioning
+
+**Opis Closure** follows [semantic versioning][SemVer] specifications.
+
+### Arbitrary object serialization
+
+We've added this feature in order to be able to support the serialization of a closure's bound object. 
+The implementation is far from being perfect, and it's really hard to make it work flawless. 
+We will try to improve this, but we can't guarantee anything. 
+So our advice regarding the `Opis\Closure\serialize|unserialize` functions is to use them with caution.

+  
+  One TextData function is also affected: `REPT()` (str_repeat).
+- `formatAsDate` correctly matches language metadata, reverting c55272e
+- Formulae that previously crashed on sub function call returning excel error value now return said value.
+  The following functions are affected `CUMPRINC()`, `CUMIPMT()`, `AMORLINC()`,
+  `AMORDEGRC()`.
+- Adapt some function error return value to match excel's error.
+  The following functions are affected `PPMT()`, `IPMT()`.
+
+### Deprecated
+
+- Calling many of the Excel formula functions directly rather than through the Calculation Engine.
+
+  The logic for these Functions is now being moved out of the categorised `Database`, `DateTime`, `Engineering`, `Financial`, `Logical`, `LookupRef`, `MathTrig`, `Statistical`, `TextData` and `Web` classes into small, dedicated classes for individual functions or related groups of functions.
+
+  This makes the logic in these classes easier to maintain; and will reduce the memory footprint required to execute formulae when calling these functions.

+
+### Added
+
+- Implemented Page Order for Xlsx and Xls Readers, and provided Page Settings (Orientation, Scale, Horizontal/Vertical Centering, Page Order, Margins) support for Ods, Gnumeric and Xls Readers [#1559](https://github.com/PHPOffice/PhpSpreadsheet/pull/1559)
+- Implementation of the Excel `LOGNORM.DIST()`, `NORM.S.DIST()`, `GAMMA()` and `GAUSS()` functions. [#1588](https://github.com/PHPOffice/PhpSpreadsheet/pull/1588)
+- Named formula implementation, and improved handling of Defined Names generally [#1535](https://github.com/PHPOffice/PhpSpreadsheet/pull/1535)
+  - Defined Names are now case-insensitive
+  - Distinction between named ranges and named formulae
+  - Correct handling of union and intersection operators in named ranges
+  - Correct evaluation of named range operators in calculations
+  - fix resolution of relative named range values in the calculation engine; previously all named range values had been treated as absolute.
+  - Calculation support for named formulae
+  - Support for nested ranges and formulae (named ranges and formulae that reference other named ranges/formulae) in calculations
+  - Introduction of a helper to convert address formats between R1C1 and A1 (and the reverse)
+  - Proper support for both named ranges and named formulae in all appropriate Readers
+    - **Xlsx** (Previously only simple named ranges were supported)
+    - **Xls** (Previously only simple named ranges were supported)
+    - **Gnumeric** (Previously neither named ranges nor formulae were supported)
+    - **Ods** (Previously neither named ranges nor formulae were supported)
+    - **Xml** (Previously neither named ranges nor formulae were supported)
+  - Proper support for named ranges and named formulae in all appropriate Writers

+    - **Xls** (Previously neither named ranges nor formulae were supported) - Still not supported, but some parser issues resolved that previously failed to differentiate between a defined name and a function name
+    - **Ods** (Previously neither named ranges nor formulae were supported)
+- Support for PHP 8.0
+
+### Changed
+
+- Improve Coverage for ODS Reader [#1545](https://github.com/phpoffice/phpspreadsheet/pull/1545)
+- Named formula implementation, and improved handling of Defined Names generally [#1535](https://github.com/PHPOffice/PhpSpreadsheet/pull/1535)
+- fix resolution of relative named range values in the calculation engine; previously all named range values had been treated as absolute.
+- Drop $this->spreadSheet null check from Xlsx Writer [#1646](https://github.com/phpoffice/phpspreadsheet/pull/1646)
+- Improving Coverage for Excel2003 XML Reader [#1557](https://github.com/phpoffice/phpspreadsheet/pull/1557)
+
+### Deprecated
+
+- **IMPORTANT NOTE:** This Introduces a **BC break** in the handling of named ranges. Previously, a named range cell reference of `B2` would be treated identically to a named range cell reference of `$B2` or `B$2` or `$B$2` because the calculation engine treated then all as absolute references. These changes "fix" that, so the calculation engine now handles relative references in named ranges correctly.
+  This change that resolves previously incorrect behaviour in the calculation may affect users who have dynamically defined named ranges using relative references when they should have used absolute references.

+
+## 1.8.0 - 2019-07-01
+
+### Security Fix (CVE-2019-12331)
+
+- Detect double-encoded xml in the Security scanner, and reject as suspicious.
+- This change also broadens the scope of the `libxml_disable_entity_loader` setting when reading XML-based formats, so that it is enabled while the xml is being parsed and not simply while it is loaded.
+  On some versions of PHP, this can cause problems because it is not thread-safe, and can affect other PHP scripts running on the same server. This flag is set to true when instantiating a loader, and back to its original setting when the Reader is no longer in scope, or manually unset.
+- Provide a check to identify whether libxml_disable_entity_loader is thread-safe or not.
+
+  `XmlScanner::threadSafeLibxmlDisableEntityLoaderAvailability()`
+- Provide an option to disable the libxml_disable_entity_loader call through settings. This is not recommended as it reduces the security of the XML-based readers, and should only be used if you understand the consequences and have no other choice.
+
+### Added

+# Want to contribute?
+
+If you would like to contribute, here are some notes and guidelines:
+
+ - All new development happens on feature/fix branches, and are then merged to the `master` branch once stable; so the `master` branch is always the most up-to-date, working code
+ - Tagged releases are made from the `master` branch
+ - If you are going to be submitting a pull request, please fork from `master`, and submit your pull request back as a fix/feature branch referencing the GitHub issue number
+ - Code style might be automatically fixed by `composer fix`
+ - All code changes must be validated by `composer check`
+ - [Helpful article about forking](https://help.github.com/articles/fork-a-repo/ "Forking a GitHub repository")
+ - [Helpful article about pull requests](https://help.github.com/articles/using-pull-requests/ "Pull Requests")
+
+## How to release
+
+1. Complete CHANGELOG.md and commit
+2. Create an annotated tag
+    1. `git tag -a 1.2.3`
+    2. Tag subject must be the version number, eg: `1.2.3`
+    3. Tag body must be a copy-paste of the changelog entries
+3. Push tag with `git push --tags`, GitHub Actions will create a GitHub release automatically

+PhpSpreadsheet is a library written in pure PHP and offers a set of classes that
+allow you to read and write various spreadsheet file formats such as Excel and LibreOffice Calc.
+
+## Documentation
+
+Read more about it, including install instructions, in the [official documentation](https://phpspreadsheet.readthedocs.io). Or check out the [API documentation](https://phpoffice.github.io/PhpSpreadsheet).
+
+Please ask your support questions on [StackOverflow](https://stackoverflow.com/questions/tagged/phpspreadsheet), or have a quick chat on [Gitter](https://gitter.im/PHPOffice/PhpSpreadsheet).
+
+## PHPExcel vs PhpSpreadsheet ?
+
+PhpSpreadsheet is the next version of PHPExcel. It breaks compatibility to dramatically improve the code base quality (namespaces, PSR compliance, use of latest PHP language features, etc.).
+
+Because all efforts have shifted to PhpSpreadsheet, PHPExcel will no longer be maintained. All contributions for PHPExcel, patches and new features, should target PhpSpreadsheet `master` branch.
+
+Do you need to migrate? There is [an automated tool](/docs/topics/migration-from-PHPExcel.md) for that.

+     * This routine calculates the LOG(GAMMA) function for a positive real argument X.
+     * Computation is based on an algorithm outlined in references 1 and 2.
+     * The program uses rational functions that theoretically approximate LOG(GAMMA)
+     * to at least 18 significant decimal digits. The approximation for X > 12 is from
+     * reference 3, while approximations for X < 12.0 are similar to those in reference
+     * 1, but are unpublished. The accuracy achieved depends on the arithmetic system,
+     * the compiler, the intrinsic functions, and proper selection of the
+     * machine-dependent constants.
+     * </p>
+     * <p>
+     * Error returns: <br />
+     * The program returns the value XINF for X .LE. 0.0 or when overflow would occur.
+     * The computation is believed to be free of underflow and overflow.

+// Adapted from Excel_Spreadsheet_Reader developed by users bizon153,
+// trex005, and mmp11 (SourceForge.net)
+// https://sourceforge.net/projects/phpexcelreader/
+// Primary changes made by canyoncasa (dvc) for ParseXL 1.00 ...
+//     Modelled moreso after Perl Excel Parse/Write modules
+//     Added Parse_Excel_Spreadsheet object
+//         Reads a whole worksheet or tab as row,column array or as
+//         associated hash of indexed rows and named column fields
+//     Added variables for worksheet (tab) indexes and names
+//     Added an object call for loading individual woorksheets
+//     Changed default indexing defaults to 0 based arrays
+//     Fixed date/time and percent formats
+//     Includes patches found at SourceForge...
+//         unicode patch by nobody
+//         unpack("d") machine depedency patch by matchy
+//         boundsheet utf16 patch by bjaenichen
+//     Renamed functions for shorter names
+//     General code cleanup and rigor, including <80 column width
+//     Included a testcase Excel file and PHP example calls
+//     Code works for PHP 5.x
+
+// Primary changes made by canyoncasa (dvc) for ParseXL 1.10 ...
+// http://sourceforge.net/tracker/index.php?func=detail&aid=1466964&group_id=99160&atid=623334
+//     Decoding of formula conditions, results, and tokens.
+//     Support for user-defined named cells added as an array "namedcells"
+//         Patch code for user-defined named cells supports single cells only.
+//         NOTE: this patch only works for BIFF8 as BIFF5-7 use a different
+//         external sheet reference structure

+ *    For an m-by-n matrix A with m >= n, the LU decomposition is an m-by-n
+ *    unit lower triangular matrix L, an n-by-n upper triangular matrix U,
+ *    and a permutation vector piv of length m so that A(piv,:) = L*U.
+ *    If m < n, then L is m-by-m and U is m-by-n.
+ *
+ *    The LU decompostion with pivoting always exists, even if the matrix is
+ *    singular, so the constructor will never fail. The primary use of the
+ *    LU decomposition is in the solution of square systems of simultaneous
+ *    linear equations. This will fail if isNonsingular() returns false.

+/**
+ * <code>
+ * Header/Footer Formatting Syntax taken from Office Open XML Part 4 - Markup Language Reference, page 1970:.
+ *
+ * There are a number of formatting codes that can be written inline with the actual header / footer text, which
+ * affect the formatting in the header or footer.
+ *
+ * Example: This example shows the text "Center Bold Header" on the first line (center section), and the date on
+ * the second line (center section).
+ *         &CCenter &"-,Bold"Bold&"-,Regular"Header_x000A_&D
+ *
+ * General Rules:
+ * There is no required order in which these codes must appear.
+ *
+ * The first occurrence of the following codes turns the formatting ON, the second occurrence turns it OFF again:
+ * - strikethrough
+ * - superscript
+ * - subscript
+ * Superscript and subscript cannot both be ON at same time. Whichever comes first wins and the other is ignored,
+ * while the first is ON.
+ * &L - code for "left section" (there are three header / footer locations, "left", "center", and "right"). When
+ * two or more occurrences of this section marker exist, the contents from all markers are concatenated, in the
+ * order of appearance, and placed into the left section.
+ * &P - code for "current page #"
+ * &N - code for "total pages"
+ * &font size - code for "text font size", where font size is a font size in points.
+ * &K - code for "text font color"
+ * RGB Color is specified as RRGGBB
+ * Theme Color is specifed as TTSNN where TT is the theme color Id, S is either "+" or "-" of the tint/shade
+ * value, NN is the tint/shade value.
+ * &S - code for "text strikethrough" on / off
+ * &X - code for "text super script" on / off
+ * &Y - code for "text subscript" on / off
+ * &C - code for "center section". When two or more occurrences of this section marker exist, the contents
+ * from all markers are concatenated, in the order of appearance, and placed into the center section.
+ *
+ * &D - code for "date"
+ * &T - code for "time"
+ * &G - code for "picture as background"
+ * &U - code for "text single underline"

+     *
+     * Based on the width and height of the bitmap we need to calculate 8 vars:
+     *     $col_start, $row_start, $col_end, $row_end, $x1, $y1, $x2, $y2.
+     * The width and height of the cells are also variable and have to be taken into
+     * account.
+     * The values of $col_start and $row_start are passed in from the calling
+     * function. The values of $col_end and $row_end are calculated by subtracting
+     * the width and height of the bitmap from the width and height of the
+     * underlying cells.
+     * The vertices are expressed as a percentage of the underlying cell width as
+     * follows (rhs values are in pixels):
+     *
+     *       x1 = X / W *1024
+     *       y1 = Y / H *256
+     *       x2 = (X-1) / W *1024
+     *       y2 = (Y-1) / H *256
+     *
+     *       Where:  X is distance from the left side of the underlying cell
+     *               Y is distance from the top of the underlying cell
+     *               W is the width of the cell
+     *               H is the height of the cell
+     * The SDK incorrectly states that the height should be expressed as a
+     *        percentage of 1024.

+## 1.0.1 - 2016-08-06
+
+### Fixed
+
+- Make spacing consistent in phpdoc annotations php-fig/cache#9 - chalasr
+- Fix grammar in phpdoc annotations php-fig/cache#10 - chalasr
+- Be more specific in docblocks that `getItems()` and `deleteItems()` take an array of strings (`string[]`) compared to just `array` php-fig/cache#8 - GrahamCampbell
+- For `expiresAt()` and `expiresAfter()` in CacheItemInterface fix docblock to specify null as a valid parameters as well as an implementation of DateTimeInterface php-fig/cache#7 - GrahamCampbell
+
+## 1.0.0 - 2015-12-11
+
+Initial stable release; reflects accepted PSR-6 specification

+# Changelog
+
+All notable changes to this project will be documented in this file, in reverse chronological order by release.
+
+## 1.0.1 - 2016-08-06
+
+### Added
+
+- Nothing.
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- Nothing.
+
+### Fixed
+
+- Updated all `@return self` annotation references in interfaces to use
+  `@return static`, which more closelly follows the semantics of the
+  specification.
+- Updated the `MessageInterface::getHeaders()` return annotation to use the
+  value `string[][]`, indicating the format is a nested array of strings.
+- Updated the `@link` annotation for `RequestInterface::withRequestTarget()`
+  to point to the correct section of RFC 7230.
+- Updated the `ServerRequestInterface::withUploadedFiles()` parameter annotation
+  to add the parameter name (`$uploadedFiles`).
+- Updated a `@throws` annotation for the `UploadedFileInterface::moveTo()`
+  method to correctly reference the method parameter (it was referencing an
+  incorrect parameter name previously).
+
+## 1.0.0 - 2016-05-18
+
+Initial stable release; reflects accepted PSR-7 specification.

+PSR Http Message
+================
+
+This repository holds all interfaces/classes/traits related to
+[PSR-7](http://www.php-fig.org/psr/psr-7/).
+
+Note that this is not a HTTP message implementation of its own. It is merely an
+interface that describes a HTTP message. See the specification for more details.
+
+Usage
+-----
+
+We'll certainly need some stuff in here.

+PSR Log
+=======
+
+This repository holds all interfaces/classes/traits related to
+[PSR-3](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md).
+
+Note that this is not a logger of its own. It is merely an interface that
+describes a logger. See the specification for more details.
+
+Installation
+------------
+
+```bash
+composer require psr/log
+```
+
+Usage
+-----
+
+If you need a logger, you can use the interface like this:
+
+```php
+<?php
+
+use Psr\Log\LoggerInterface;
+
+class Foo
+{
+    private $logger;
+
+    public function __construct(LoggerInterface $logger = null)
+    {
+        $this->logger = $logger;
+    }
+
+    public function doSomething()
+    {
+        if ($this->logger) {
+            $this->logger->info('Doing work');
+        }
+           
+        try {
+            $this->doSomethingElse();
+        } catch (Exception $exception) {
+            $this->logger->error('Oh no!', array('exception' => $exception));
+        }
+
+        // do something useful
+    }
+}
+```
+
+You can then pick one of the implementations of the interface to get a logger.
+
+If you want to implement the interface, you can require this package and
+implement `Psr\Log\LoggerInterface` in your code. Please read the
+[specification text](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md)
+for details.

+PHP FIG Simple Cache PSR
+========================
+
+This repository holds all interfaces related to PSR-16.
+
+Note that this is not a cache implementation of its own. It is merely an interface that describes a cache implementation. See [the specification](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-16-simple-cache.md) for more details.
+
+You can find implementations of the specification by looking for packages providing the [psr/simple-cache-implementation](https://packagist.org/providers/psr/simple-cache-implementation) virtual package.

+Symfony Polyfill / Php72
+========================
+
+This component provides functions added to PHP 7.2 core:
+
+- [`spl_object_id`](https://php.net/spl_object_id)
+- [`stream_isatty`](https://php.net/stream_isatty)
+
+On Windows only:
+
+- [`sapi_windows_vt100_support`](https://php.net/sapi_windows_vt100_support)
+
+Moved to core since 7.2 (was in the optional XML extension earlier):
+
+- [`utf8_encode`](https://php.net/utf8_encode)
+- [`utf8_decode`](https://php.net/utf8_decode)
+
+Also, it provides constants added to PHP 7.2:
+- [`PHP_FLOAT_*`](https://php.net/reserved.constants#constant.php-float-dig)
+- [`PHP_OS_FAMILY`](https://php.net/reserved.constants#constant.php-os-family)

+=========
+
+2.8.0
+-----
+
+ * Deprecated usage of a colon in an unquoted mapping value
+ * Deprecated usage of @, \`, | and > at the beginning of an unquoted string
+ * When surrounding strings with double-quotes, you must now escape `\` characters. Not
+   escaping those characters (when surrounded by double-quotes) is deprecated.
+
+   Before:
+
+   ```yml
+   class: "Foo\Var"
+   ```
+
+   After:
+
+   ```yml
+   class: "Foo\\Var"
+   ```
+
+2.1.0
+-----
+
+ * Yaml::parse() does not evaluate loaded files as PHP files by default
+   anymore (call Yaml::enablePhpParsing() to get back the old behavior)

+如何贡献我的源代码
+===
+
+此文档介绍了 ThinkPHP 团队的组成以及运转机制，您提交的代码将给 ThinkPHP 项目带来什么好处，以及如何才能加入我们的行列。
+
+## 通过 Github 贡献代码
+
+ThinkPHP 目前使用 Git 来控制程序版本，如果你想为 ThinkPHP 贡献源代码，请先大致了解 Git 的使用方法。我们目前把项目托管在 GitHub 上，任何 GitHub 用户都可以向我们贡献代码。
+
+参与的方式很简单，`fork`一份 ThinkPHP 的代码到你的仓库中，修改后提交，并向我们发起`pull request`申请，我们会及时对代码进行审查并处理你的申请并。审查通过后，你的代码将被`merge`进我们的仓库中，这样你就会自动出现在贡献者名单里了，非常方便。
+
+我们希望你贡献的代码符合：
+
+* ThinkPHP 的编码规范
+* 适当的注释，能让其他人读懂
+* 遵循 Apache2 开源协议
+
+**如果想要了解更多细节或有任何疑问，请继续阅读下面的内容**
+
+### 注意事项
+
+* 本项目代码格式化标准选用 [**PSR-2**](http://www.kancloud.cn/thinkphp/php-fig-psr/3141)；
+* 类名和类文件名遵循 [**PSR-4**](http://www.kancloud.cn/thinkphp/php-fig-psr/3144)；
+* 对于 Issues 的处理，请使用诸如 `fix #xxx(Issue ID)` 的 commit title 直接关闭 issue。
+* 系统会自动在 PHP 7.1 ~ 7.3 上测试修改，请确保你的修改符合 PHP 7.1 ~ 7.3 的语法规范；
+* 管理员不会合并造成 CI faild 的修改，若出现 CI faild 请检查自己的源代码或修改相应的[单元测试文件](tests)；
+
+## GitHub Issue
+
+GitHub 提供了 Issue 功能，该功能可以用于：
+
+* 提出 bug
+* 提出功能改进
+* 反馈使用体验
+
+该功能不应该用于：
+
+ * 提出修改意见（涉及代码署名和修订追溯问题）
+ * 不友善的言论
+
+## 快速修改
+
+**GitHub 提供了快速编辑文件的功能**
+
+1. 登录 GitHub 帐号；
+2. 浏览项目文件，找到要进行修改的文件；
+3. 点击右上角铅笔图标进行修改；
+4. 填写 `Commit changes` 相关内容（Title 必填）；
+5. 提交修改，等待 CI 验证和管理员合并。
+
+**若您需要一次提交大量修改，请继续阅读下面的内容**
+
+## 完整流程
+
+1. `fork`本项目；
+2. 克隆(`clone`)你 `fork` 的项目到本地；
+3. 新建分支(`branch`)并检出(`checkout`)新分支；
+4. 添加本项目到你的本地 git 仓库作为上游(`upstream`)；
+5. 进行修改，若你的修改包含方法或函数的增减，请记得修改[单元测试文件](tests)；
+6. 变基（衍合 `rebase`）你的分支到上游 master 分支；
+7. `push` 你的本地仓库到 GitHub；
+8. 提交 `pull request`；
+9. 等待 CI 验证（若不通过则重复 5~7，GitHub 会自动更新你的 `pull request`）；
+10. 等待管理员处理，并及时 `rebase` 你的分支到上游 master 分支（若上游 master 分支有修改）。
+
+*若有必要，可以 `git push -f` 强行推送 rebase 后的分支到自己的 `fork`*
+
+*绝对不可以使用 `git push -f` 强行推送修改到上游*
+
+### 注意事项
+
+* 若对上述流程有任何不清楚的地方，请查阅 GIT 教程，如 [这个](http://backlogtool.com/git-guide/cn/)；
+* 对于代码**不同方面**的修改，请在自己 `fork` 的项目中**创建不同的分支**（原因参见`完整流程`第9条备注部分）；
+* 变基及交互式变基操作参见 [Git 交互式变基](http://pakchoi.me/2015/03/17/git-interactive-rebase/)
+
+## 推荐资源
+
+### 开发环境
+
+* XAMPP for Windows 5.5.x
+* WampServer (for Windows)
+* upupw Apache PHP5.4 ( for Windows)
+
+或自行安装
+
+- Apache / Nginx
+- PHP 7.1 ~ 7.3
+- MySQL / MariaDB
+
+*Windows 用户推荐添加 PHP bin 目录到 PATH，方便使用 composer*
+
+*Linux 用户自行配置环境， Mac 用户推荐使用内置 Apache 配合 Homebrew 安装 PHP 和 MariaDB*

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"

+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "{}"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.

+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the

+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "{}"

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+~~~
+
+## 用法示例
+
+
+~~~php
+<?php
+namespace think;
+
+require __DIR__.'/vendor/autoload.php';
+
+// 设置模板引擎参数
+$config = [
+	'view_path'	=>	'./template/',
+	'cache_path'	=>	'./runtime/',
+	'view_suffix'   =>	'html',
+];
+
+$template = new Template($config);
+// 模板变量赋值
+$template->assign(['name' => 'think']);
+// 读取模板文件渲染输出
+$template->fetch('index');
+// 完整模板文件渲染
+$template->fetch('./template/test.php');
+// 渲染内容输出
+$template->display($content);
+~~~
+
+支持静态调用
+
+~~~
+use think\facade\Template;
+
+Template::config([
+	'view_path'	=>	'./template/',
+	'cache_path'	=>	'./runtime/',
+	'view_suffix'   =>	'html',
+]);
+Template::assign(['name' => 'think']);
+Template::fetch('index',['name' => 'think']);
+Template::display($content,['name' => 'think']);

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+# think-view
+
+ThinkPHP6.0 Think-Template模板引擎驱动
+
+
+## 安装
+
+~~~php
+composer require topthink/think-view
+~~~
+
+## 用法示例
+
+本扩展不能单独使用，依赖ThinkPHP6.0+
+
+首先配置config目录下的template.php配置文件，然后可以按照下面的用法使用。
+
+~~~php
+
+use think\facade\View;
+
+// 模板变量赋值和渲染输出
+View::assign(['name' => 'think'])
+	// 输出过滤
+	->filter(function($content){
+		return str_replace('search', 'replace', $content);
+	})
+	// 读取模板文件渲染输出
+	->fetch('index');
+
+
+// 或者使用助手函数
+view('index', ['name' => 'think']);
+~~~
+
+具体的模板引擎配置请参考think-template库。
