title: Is there a way to access HTTP GET variables without $_GET
body: <p>Is there a way to access HTTP GET variables in PHP without using <code>$_GET</code> or <code>$_REQUEST</code>? I'm asking because I know that <code>$_POST</code> isn't populated if the POST isn't sent through a form and I want to make sure that using <code>$_GET</code> doesn't have similar problems.</p>
