I have the same problems, but I am using PHP4 and its session handling functions. Every time I try to register the object, the next page is unable to handle this like the original object with its functions. This made me believe it is not possible to do that. But as I saw the content from php.net I got very surprised because, it's possible too. Now I am sitting here, wondering why this doesn't work with my classes, altough am using PHP4. So I ask if somebody can help me with my code. I will put the problem code here in my next forum posting.
