PHP framework for HTTP and building RESTful webservice clients

Guzzle is a PHP 5.3+ HTTP client and framework for building web service clients.

• Supports GET, HEAD, POST, DELETE, PUT, and OPTIONS
• Allows full access to request and response headers
• Persistent connections are implicitly managed by Guzzle, resulting in huge performance benefits
• Send requests in parallel
• Cookie sessions can be maintained between requests using the CookiePlugin
• Allows custom entity bodies to be sent in PUT and POST requests, including sending data from a PHP stream
• Responses can be cached and served from cache using the caching reverse proxy plugin
• Failed requests can be retried using truncated exponential backoff
• Entity bodies can be validated automatically using Content-MD5 headers
• All data sent over the wire can be logged using the LogPlugin
• Automatically requests compressed data and automatically decompresses data
• Subject/Observer signal slot system for unobtrusively modifying request behavior
• Supports all of the features of libcurl including authentication, redirects, SSL, proxies, etc
• Web service client framework for building future-proof interfaces to web services

HTTP basics:

<?php

use Guzzle\Http\Message\RequestFactory;

$request = RequestFactory::get('http://www.example.com/');
$response = $request->send();

$response = RequestFactory::head('http://www.example.com/')->send();
$response = RequestFactory::delete('http://www.example.com/')->send();

// Send a PUT request with custom headers
$response = RequestFactory::put('http://www.example.com/upload', array(
    'X-Header' => 'My Header'
), 'body of the request')->send();

// Send a PUT request using the contents of a PHP stream as the body
$response = RequestFactory::put('http://www.example.com/upload', array(
    'X-Header' => 'My Header'
), fopen('http://www.test.com/', 'r'));

// Create a POST request with a file upload (notice the @ symbol):
$request = RequestFactory::post('http://localhost:8983/solr/update', null, array (
    'custom_field' => 'my value',
    'file' => '@/path/to/documents.xml'
));

// Create a POST request and add the POST files manually
$request = RequestFactory::post('http://localhost:8983/solr/update')
    ->addPostFiles(array(
        'file' => '/path/to/documents.xml'
    ));

// Responses are objects
echo $response->getStatusCode() . ' ' . $response->getReasonPhrase() . "\n";

// Requests and responses can be cast to a string to show the raw HTTP message
echo $request . "\n\n" . $response;

// Create the request objects manually
$getRequest = new Guzzle\Http\Message\Request('GET', 'http://www.example.com/');
$putRequest = new Guzzle\Http\Message\EntityEnclosingRequest('PUT', 'http://www.example.com/');

// Create a request based on an HTTP message
$request = RequestFactory::fromMessage(
    "PUT / HTTP/1.1\r\n" .
    "Host: test.com:8081\r\n" .
    "Content-Type: text/plain"
    "Transfer-Encoding: chunked\r\n" .
    "\r\n" .
    "this is the body"
);

Send requests in parallel:

<?php
use Guzzle\Http\Pool\Pool;
use Guzzle\Http\Pool\PoolRequestException;

$pool = new Pool();
$pool->add(RequestFactory::get('http://www.google.com/'));
$pool->add(RequestFactory::head('http://www.google.com/'));
$pool->add(RequestFactory::get('https://www.github.com/'));

try {
    $pool->send();
} catch (PoolRequestException $e) {
    echo "The following requests encountered an exception: \n";
    foreach ($e as $exception) {
        echo $exception->getRequest() . "\n" . $exception->getMessage() . "\n";
    }
}

Web service clients:

<?php

$client = new Guzzle\Service\Client('http://www.example.com/api/v1');

// Relative URL of a nested resource
$request = $client->get('index.php');
// Relative URL that overwrites the path of the base URL
$request = $client->get('/test/123.php?a=b');
