the solution worked me this..

static function db ()     {         try {             $db = db::connection()->getpdo();         }         catch (pdoexception $e) {             self::fatal(                 "an error occurred while connecting database. ".                 "the error reported server was: ".$e->getmessage()             );         }         return $db;     }
