The manual says:

> If you are using $HTTP_SESSION_VARS/$_SESSION, do not use 
> session_register(), session_is_registered() and session_unregister().

If that's the case, how do I unregister $_SESSION variables? Do I just 
use unset() or is there another way?

I'm pretty new to PHP and I'm just getting started using sessions. The 
book I'm using to learn sessions isn't new enough to include how to deal 
with the new $_SESSION global variables array, and the manual's dire 
warning isn't explained thoroughly enough for me.
