For us novices, can you please share how you would do this with

The method you posted is for register_gkobals on, which it won'tr

You can store the value in a session variable
session_start();
if (isset($_HTTP_SESSION_VARS['your_variable_name'])) {

Rather than using isset() you may need to use 
session_is_registered().  This is specifically for checking the 
existence of a session variable.  I would do something like

<?php

// need this on all pages where you want to work with // the session 
var
session_start();

// Check for the existence of the session var and create
// it if it doesn't exist
if (!session_is_registered("ses_username")) {
        session_register("ses_username");
}
// Are we getting a form var thru ?  if so pop it into the session var
if (isset($frm_username)) {
        $ses_username = $frm_username;
}
// then in your scripts you can do
do_my_amazing_function($ses_username);
?>

As long as you have session_start() at the beginning of each script, 
$ses_username is now available across scripts.

$value=$_HTTP_SESSION_VARS['your_variable_name']; //get the value
}else{
$_HTTP_SESSION_VARS['your_variable_name']=new value;
}

</snip>

Hope that helps.
