Using vB data in another script...

[Admin]

PHP Code:

<?php
error_reporting(7);
chdir('/home/user/htdocs/forums');
require('./global.php');

if ($bbuserinfo['userid'] != 0) {
    $username = $bbuserinfo['username'];
    echo "Welcome back, <b>$username</b>.";
}

?>

Change the path in the chdir() function to the real one.
