Exactly. 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 don't know if recent 
versions of PHP still _need_ this)

I would suggest, unsetting the array in the next_page (or whatever) after you 
don't need it anymore:
