Създаване на обект по подразбиране от празна стойност ( stdClass? )

Скриптът работи добре, но само когато извличам групите на потребителя, се казва:

SteamUser.php (132): Създаване на обект по подразбиране от празна стойност

. . Вече се опитах да използвам асоциативни масиви, но не се получи; може би с това, че всичко е ново. -_-

Така че изобщо не мога да задам error_reporting(0) или ini_set.

Използвах и new stdClass() като опит. Но и това не го пуснах.
