garbage collection - Can I trust PHP __destruct() method to be called?

Question

In PHP5, is the __destruct() method guaranteed to be called for each object instance? Can exceptions in the program prevent this from happening?

Answer 1

It's also worth mentioning that, in the case of a subclass that has its own destructor, the parent destructor is not called automatically.

You have to explicitly call parent::__destruct() from the subclass __destruct() method if the parent class does any required cleanup.
