hi tedd,

if I may suggest this "model"

$_SESSION
{
    [6156]
    {
        [first_name]    => Diane
        [last_name]     => Cable
    }

    [7030]
    {
        [first_name]    => Fred
        [last_name]    => Cago
    }

    [656]
    {
        [first_name]    => Helen
        [last_name]    => Cahalan
    }
}
main reason - if you sort by first or last name you will lose "index".
this way is index always "linked" to first/last name.

foreach ($_SESSION as $key => $value)
{
    echo $_SESSION[$key]['last_name'].',
'.$_SESSION[$key]['first_name'].'<br>';
}

didn't test it, though :-)
