PHP is correct in destroying session variables with no value.
This keeps the session file size down when a variable obviously of no worth is added.
Whether you use $_session or session_register() is up to the server design and developer preference.
I am hoping someone has some information on wether you can add wildcards to your
session_is_registered() variable name.
e.g session_is_registered("order*");
If this is not the case...
One could do this kind of thing by Physically opening the session file and searching through it with
posix style string matching.
Not that it would be recommended.
ANY comments or knowledge would be appreciated
