# Guzzle, PHP HTTP client [](https://github.com/guzzle/guzzle/releases) [](https://github.com/guzzle/guzzle/actions?query=workflow%3ACI) [](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(); ``` ## Help and docs We use GitHub issues only to discuss bugs and new features.
