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 :-)
