I'm new to OOP, so I'm trying to get my head around classes. I think I get it now, but how do I preserve my objects between calls to a page. I can use a session for variables, but what about class objects?
Am I missing something basic?
You'll need to recreate your objects between calls.
Think of web programming as very small programs that start when a user requests a page and end when the page is done processing. Using cookies you can differentiate multiple users.
Your code will be a lot cleaner if you don't try to save objects in sessions.
