RTFM again. Sessions depends on a number of factors including your version of
PHP and the setting of register_globals.
Basically if you're going to be using $_SESSION then you don't use
session_register(). You just assign the value directly to $_SESSION.
<?php // test-session.php
session_start();
if (!isset($_SESSION['studentid'])) { $_SESSION['studentid'] = 24; }
if (isset($_SESSION['studentid']))
{
$_SESSION['studentid']++;
$id = $_SESSION['studentid'];
echo "\$id= $id<br>";
}
?>
