Agreed, sessions is often the best method when you have to pass
arrays. You can also use the serialize/unserialize to pass the array
with the POST method.

more information on how to accomplish the session method:
http://us.php.net/manual/en/function.session-register.php

and the serialize/unserialize method: http://us.php.net/serialize
