Re: Learning PHP Sessions

* session_register('myvar'); creates a session var called $myvar * session_start(); needs to be called from the top of each script that will need the session var $myvar * session_destroy('myvar'); rids you of $myvar completely. * session_destroy('HTTP_SESSION_VARS'); rids you off *all* currently registered session vars Note that a variable used in this way is refered to as 'myvar' and referenced a snormal within the script as: $myvar HTH you out.
