if you use CLI then u can check them for their existence but in the browser, HTTP_HOST will be available any time.

 if (!empty($_SERVER['HTTP_HOST'])) {
    define('CURRENT_PAGE', basename($_SERVER['HTTP_HOST']));
 }

 if (!empty($_SERVER['REQUEST_URI'])) {
     define('CURRENT_PAGE', basename($_SERVER['REQUEST_URI']));
 }
