Best client that I know is: http://docs.guzzlephp.org/en/latest/

There is already bundle that integrates it into Symfony2 project: https://github.com/8p/GuzzleBundle

$client   = $this->get('guzzle.client');

// send an asynchronous request.
$request = $client->createRequest('GET', 'http://httpbin.org', ['future' => true]);
// callback
$client->send($request)->then(function ($response) {
    echo 'I completed! ' . $response;
});

// optional parameters
$response = $client->get('http://httpbin.org/get', [
    'headers' => ['X-Foo-Header' => 'value'],
    'query'   => ['foo' => 'bar']
]);
$code = $response->getStatusCode();
$body = $response->getBody();

// json response
$response = $client->get('http://httpbin.org/get');
$json = $response->json();

// extra methods
$response = $client->delete('http://httpbin.org/delete');
$response = $client->head('http://httpbin.org/get');
$response = $client->options('http://httpbin.org/get');
$response = $client->patch('http://httpbin.org/patch');
$response = $client->post('http://httpbin.org/post');
$response = $client->put('http://httpbin.org/put');
