I'd say not to both with serialize. Your just adding extra work when
there is no need to.
It is possible to pass Objects across Sessions. I do it on my
E-Commerce site by using a Shopping Cart object (it even says so on
php.net!). Are you sure there is nothing wrong in the Class (that it is
setting the data that you want correctly)? Try...
if (isset($_SESSION['session_object'])) {
// do something
}
.... to see if the session is actually.
(I will check my code later when I get home to see if this is correct)
Tryst

i'd try using serialize() to turn the object into a string which can

sessions work by using cookies, and cookies can't take php objects
