Когда я пытаюсь:

 $coreBootstrap = array_merge(array_diff($coreBootstrap, array('setsystemtime')));

Я получаю это сообщение:
«array_merge (): Аргумент # 1 не является массивом в ….» Мне нужно удалить setsystemtime, но я не могу достичь его, я пробовал также array_search, но я получаю похожую ошибку.
Это php 5.4.4

Получив помощь, я понял, что это объект. Мне нужно, чтобы часть объекта «setsystemtime» и их значения были удалены.

Есть идеи?
Благодарю вас!
