Criando objeto padrão do valor vazio
$res = new \stdClass();
$res->success = false;
Alex G'h
$res = new \stdClass();
$res->success = false;// This message has been E_STRICT for PHP <= 5.3. Since PHP 5.4, it was unluckilly changed to E_WARNING. Since E_WARNING messages are useful, you don't want to disable them completely.
// To get rid of this warning, you must use this code:
if (!isset($res))
$res = new stdClass();
$res->success = false;
// this code is from @TMS' answer on the source
