README

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();
$res = $client->get('https://api.github.com/user', ['auth' =>  ['user', 'pass']]);
echo $res->getStatusCode();
// "200"
echo $res->getHeader('content-type');
// 'application/json; charset=utf8'
echo $res->getBody();
// {"type":"User"...'

// Send an asynchronous request.
$request = new \GuzzleHttp\Psr7\Request('GET', 'http://httpbin.org');
$promise = $client->sendAsync($req)->then(function ($response) {
    echo 'I completed! ' . $response;
});
$promise->wait();

Installing Guzzle

The recommended way to install Guzzle is through Composer.

# Install Composer
curl -sS https://getcomposer.org/installer | php

Next, run the Composer command to install the latest stable version of Guzzle:

composer.phar require guzzlehttp/guzzle

After installing, you need to require Composer's autoloader:

require 'vendor/autoload.php';

You can then later update Guzzle using composer:

composer.phar update
