* 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.
