SESSION variables cheat-sheet (PHP)

Need to know, or get a handle on SESSION variables in your dynamic sites for your PHP?

This is a refrence "cheat sheet," not a tutorial , so I provide tutorial links at the end.

Initialize Session

This must be at the top of every page that will call/use a Session variable.

<?php session_start(); ?>

Register (declare) a Session variable

To add a Session variable that will be carried till the browser is closed or you kill it yourself.

<?php session_register("mySessionVariable"); ?>

Assigning value to a Session variable

Values added to a Session variable can be letters (ABCabc), numbers (1, 200, 999.99, etc.) making them good for usernames/userID's when logged into a site.

<?php $_SESSION["mySessionVariable"] = "MEMBER"; ?>

Unregister a Session variable

Logging out requires we unregister any and all Session variables used for our application and the users' account.

<?php session_unregister("mySessionVariable"); ?>

Destroy a Session
