Guzzle, PHP HTTP client

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.
• 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.

$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();
