to get rid of the first argument $url in the callback function, remove the first element in the array $matches using array_shift() function

function get($url, $callback) {
	$matches = array();
	if (preg_match('~' . $url . '~', $_SERVER['REQUEST_URI'], $matches)) {
                array_shift($url);
		return call_user_func_array($callback, $matches);
	}
}
