It's difficult because PHP does not handle serialization of objects very 
well.

The correct way would be to store it in the $_SESSION.  However, you 
have to be careful that the object doesn't save any external resources 
such as database links, which will not be valid when it is reloaded.

Additionally, when your page terminates, the PHP calls the object's 
destructor, but does not call the object's constructor when it is read 
back into storage.  This means the constructor will be called once for 
the object, but the destructor called many times.

One other thing - the $_SESSION isn't real efficient for larger data 
structures; I wouldn't recommend storing large objects in it.
