And if cURL was more easy on PHP ?

cool_url.php

<?php

    //maybe, do a source that works like a client with cURL could be hard and boring. 
    // A fluent interface would awesome. 
    // Anyway, the library can be used only to fun and study to learn how HTTP works in lower lever. 
    
    use Saturno\CoolUrl\Client as cu; 
    
    cu::create()->target("http://example.com/join")
               ->setMethod('POST')
               ->setParams(array(
                        'login' => 'foo',
                        'password' => 'barbaz', 
                   )
               )
               ->execute();
