But just to mention it at this point: if you have script-output (echo, print, print_r etc.) before any operation on $_SESSION, you should call start_session() at the start of the script.

I would suggest, unsetting the array in the next_page (or whatever) after you don't need it anymore: unset($_SESSION['my_array']); > Another option would be to send the request as a post, and > serialize the array into a hidden variable in your form; that way you won't > have to worry (as much) about size constraints.
