I figured it out. Here is the code I use if anyone else needs it.

<?php
$root_path = $_SERVER['DOCUMENT_ROOT'];
chdir($root_path."/forum/");
require($root_path."/forum/global.php");
require_once($root_path."/forum/includes/functions_login.php");
$username = $vbulletin->userinfo['username'];
$userid = $vbulletin->userinfo['userid'];
if ($userid !=0) 
    {     
    echo "Hello $username"; 
    } 
else { 
    echo "No account logged in"; 
    } 
?>
