The @ prefix is banned from all code I go anywhere near - it's evil! I've used the following 'V' function for a long time, primarily for accessing the superglobals but it works for any array.
<?php
session_start();
$_SESSION['first_name'] = $first_name = V($_SESSION, 'first_name');
function V($arr, $key, $def = null) {
return isset($arr[$key]) ? $arr[$key] : $def;
}
?>
