Building query string programmatically in Guzzle?

In my PHP Guzzle client code, I have something like

$c = new Client('http://test.com/api/1.0/function');

$request = $c->get('?f=4&l=2&p=3&u=5');

but instead I want to have something like:

$request->set('f', 4);
$request->set('l', 2);
$request->set('p', 3);
$request->set('u', 5);

Is it possible in Guzzle? From the documentation and random googling it would seem it is, but I can’t find exactly how.

Answer

Guzzle 6 – you could use query option param

// Send a GET request to /get?foo=bar
$client->request('GET', '/get', ['query' => ['foo' => 'bar']]);
