Description:
------------
I have a php class Customer which has and Object variable 'Address'. The class 'Address' in turn has an object variable 'Zip'.

Customer
   Address
      Zip


In the file 'CustomerTest.php' - 
I am creating a new Zip object and assigning this zip object to a new Address object which in turn is assigned to a new Customer object. 

Now I am printing the instance variables of the Zip object (two String values). After this I am assigning a new Zip object to the above 'Address object' and again printing the instance variables of the Zip object to the screen. As expected these values differ from the above print command.
Now I am assigning the Customer object to SESSION. Now on a different php page using the Customer object stored in session, if I print the instance variables of zip object, I get the OLD VALUES but not the new ones which I have modified.

I reproduced the same code using servlets which functioned properly as expected unlike php.

Please look into this.
