9Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and
10trivial to integrate with web services.
11
12- Simple interface for building query strings, POST requests, streaming large
13 uploads, streaming large downloads, using HTTP cookies, uploading JSON data,
14 etc...
15- Can send both synchronous and asynchronous requests using the same interface.
16- Uses PSR-7 interfaces for requests, responses, and streams. This allows you
17 to utilize other PSR-7 compatible libraries with Guzzle.
18- Supports PSR-18 allowing interoperability between other PSR-18 HTTP Clients.
19- Abstracts away the underlying HTTP transport, allowing you to write
20 environment and transport agnostic code; i.e., no hard dependency on cURL,
21 PHP streams, sockets, or non-blocking event loops.
22- Middleware system allows you to augment and compose client behavior.

24```php
25$client = new \GuzzleHttp\Client();
26$response = $client->request('GET', 'https://api.github.com/repos/guzzle/guzzle');
27
28echo $response->getStatusCode(); // 200
29echo $response->getHeaderLine('content-type'); // 'application/json; charset=utf8'
30echo $response->getBody(); // '{"id": 1420053, "name": "guzzle", ...}'
31
32// Send an asynchronous request.
33$request = new \GuzzleHttp\Psr7\Request('GET', 'http://httpbin.org');
34$promise = $client->sendAsync($request)->then(function ($response) {
35 echo 'I completed! ' . $response->getBody();
36});
37
38$promise->wait();
