PHP Code:

    $datecut = TIMENOW - $vboptions['cookietimeout'];
    $headerguests = $DB_site->query_first("
        SELECT COUNT(*) AS count 
        FROM session
        WHERE userid = 0 AND lastactivity > $datecut
    ");
    $headerusers = $DB_site->query_first("
        SELECT COUNT(DISTINCT(userid)) AS count 
        FROM session 
        WHERE session.userid > 0 AND session.lastactivity > $datecut
    ");
    $headerguests = $headerguests['count'];
    $headerusers = $headerusers['count'];
    $totalonline = $headerguests + $headerusers;
