serializing objects that hold other objects

[Perttu Pulkkinen]

Hi!
I have been thinking (not testing yet) what happens if I have something
like:

class a
{ ...}
class b
{ var a_item = new a(); ...}

$john = new b();
$ser = serialize($john);

Is the definition of class a also serialized with john and definition of
class b?

Yes, class a will be serialized as a property of class b (John)

No, the class definition is not stored. If you unserialize the string before
the class is defined the object will become of the class
__PHP_Incomplete_Class.

You are always required to define your class before serialize or
unserialize operation.
If defined you can serialize and unserialize all objects (even with
child objects). But you can not properly serialize and unserialize a
class with some php resource as its member.

Hope it will help.
