distinguishing session and form vars

[Anon]

If I've got a session variable named UserID and a variable from a form named UserID, how do I distinguish the two when coding?

Thanks in advance!

well, i would suggest changing the one of the variable's names but the session var is here:

$HTTP_SESSION_VARS['UserID'];

and the form var is in one of these depending if you are using a post or get method:

$HTTP_GET_VARS['UserID'];
$HTTP_POST_VARS['UserID'];

So they don't overwrite one another at all?

They do not overwrite eachother in the HTTP*VARS arrays.

if you let PHP register the vars in the global scope, the the vars from the session will overwrite the vars from the POST or GET methods (for security reasons).
