Among $_REQUEST, $_GET and $_POST which one is the fastest?

Question

Which of these code will be faster?

$temp = $_REQUEST[\'s\'];

or

if (isset($_GET[\'s\'])) {
  $temp = $_GET[\'s\'];
}
else

It's ugly and I wouldn't recommended it as a final solution when pushing code live, but while building rest functions, it's sometimes handy to have a 'catch-all' parameter grabber:

public static function parseParams() {
    $params = array();
    switch($_SERVER['REQUEST_METHOD']) {
        case "PUT":
        case "DELETE":
            parse_str(file_get_contents('php://input'), $params);
            $GLOBALS["_{$_SERVER['REQUEST_METHOD']}"] = $params;
            break;
        case "GET":
            $params = $_GET;
            break;
        case "POST":
            $params = $_POST;
            break;
        default:
            $params = $_REQUEST;
            break;
    }
    return $params;
}

Someone creative could probably even add to it to handle command line parameters or whatever comes from your IDE. Once you decide what a given rest-function is doing, you can pick one appropriate for that given call to make sure you get what you need for the deploy version. This assumes 'REQUEST_METHOD' is set.
