Alibaba Cloud SDK for PHP is a development kit that supports quick access to products, dependency on [Alibaba Cloud Client for PHP][client].


## Release Notes
We developed a new kernel on the principle of `eliminating known issues` and `compatible with old grammar`, adding the following features:
- [Support Composer][packagist]
- [Support for multiple client and client profiles][clients]
- [Result is a powerful object][result]
- [More flexible configuration per request][request]


## 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 SDK for PHP as a dependency:
```
composer require alibabacloud/sdk
```
> 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 through Composer and other ways.


## Online Demo
[API Explorer](https://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.


## 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). Before request, please [Understanding the Clients][clients], after request, please [Understanding the Result][result].

> Currently only some Alibaba Cloud products are supported, [Supported Products](/SUPPORTED-EN.md), For products that are not supported, you can use [Alibaba Cloud Client for PHP][request] to initiate custom requests, and you can use [API Explorer](https://api.aliyun.com) to generate Alibaba Cloud Client for PHP code online.

```php

    $request = Ecs::v20140526()->describeRegions();
    
    // Set options/parameters and execute request
    $result = $request->withResourceType('type') // API parameter
                      ->withInstanceChargeType('type') // API parameter
                      ->client('client1') // Specify the client for send
