True. But since we do need objects to persist, we invent things like
sessions and serialization so our scripts can *pretend* they persist and
will never know the difference.

Behaviour is "the methods". And they surely persist since the source
files are not destroyed after each request. All instances of a class
share the same methods, after all.

Why do you keep insisting that I must consider __sleep() to be a
destructor if I consider __wakeup() to be a constructor?

Consider:

1) __sleep() is called before the corresponding __wakeup() -- by your
logic this would mean the destructor is called before the constructor

2) __sleep() is called on a different object than the corresponding
__wakeup() -- so it cannot be the destructor corresponding to __wakeup()

3) __sleep() does not destroy anything. On the contrary, it helps to
preserve something. It is therefore not a destructor.

Greetings,
Thomas
