that's some of my scripts I once used. have a look at it. it won't run instantly, since I just took them from a collection of classes
hth /Dorgon
the most interesting part will be:
// initialize global session object session_start();
if (isset($_SESSION)) { // php versions >= 4.1.0
if (!isset($_SESSION['userSess'])) {
$_SESSION['userSess'] = new UserSession();
$sess =& $_SESSION['userSess'];
$sess->init();
}
else {
$sess =& $_SESSION['userSess'];
$_SESSION['userSess']->reuse();
}
}
else { // for downward compatibility to old php version (< 4.1.0)
if (!isset($userSess)) {
$userSess = new UserSession();
$sess =& $userSess;
$userSess->init();
session_register("userSess");
}
else {
$sess =& $userSess;
$userSess->reuse();
session_register("userSess");
}

Does anyone know of a working snippet to manage sessions using any combination of Register_Global and pre/post php v4.1?
Would love to look at some examples ..
