Ok that didn't work exactly how I needed. The two apps are in different databases. So I'm using this code

PHP Code:

//connect to database
$hostname = "localhost";
$username = "username";
$password = "password";
$dbName = "vBulletin";
$conn = MYSQL_CONNECT($hostname,$username,$password) or die(mysql_error());
@mysql_select_db("$dbName") or die("Unable to select database");

$userid = intval($_COOKIE[bbuserid]);
$password = addslashes($_COOKIE[bbpassword]);
$result = mysql_query("SELECT username, userid FROM user WHERE userid=$userid AND MD5(CONCAT(password, 'licensenumber')) = '$password'");
$user = mysql_fetch_array($result); 


Whenc I call $userid I get the right user id of the person logged in. But if I call $username I get the username used to log into MySQL not the vBulletin user???
