hi all, i need a way to get the path to the parent folder of the folder i am in. one "dirty" way i found is this - require_once(dirname(__FILE__) . DIRECTORY_SEPARATOR .

             ".."              . DIRECTORY_SEPARATOR .
             "config.php");

i can also explode() and reassemble all folders except the last, but this looks also dirty... is there a direct way? iv
