Using register_shutdown_function is unnecessary:

<?php

session_start();
if(ini_get('register_globals') AND !isset($session_global_var)){
        $session_global_var = array();
}

session_register('session_global_var');

if(ini_get('register_globals')){
        $SESSION =& $session_global_var;
}else{
        $SESSION =& $HTTP_SESSION_VARS['session_global_var'];
}

?>

Use the above code and you will be able to add/remove anything from the
$SESSION array and it will be reflected in the next request.
