PHP Complete Object Graph not stored in Session

Question

Hello,

I have read other posts on stack overflow on the issue but my question is a little different..

When storing an object in the Session does PHP save the Complete Object Graph in the session?

I am having problems accessing some of the properties of the Object AFTER it is read from the Session.

The object i am storing has complex type properties with some of them being objects of classes that inherit from other classes, so serializing the object before storing it in the session might be a little "expensive".

What am i missing with Objects and their storage in the Session. Are there limits?

Thank you.

Complex object graphs are serialized fine. Even cyclic references can be serialized. You can't serialize resources though, and certain built-in object types. Generally speaking, serialization is a very expensive operation. You should not rely on it as a shared memory strategy.
