might just be me but is selecting everything from the usertable nessisary?

PHP Code:

           $validateinfo = $DB_site->query_first(" 
                SELECT user.* 
                FROM user 
            "); 


that will cause some slowups imo using something like:

PHP Code:

           $validateinfo = $DB_site->query_first(" 
                SELECT user.userid, user.username, user.membergroupids (example of rows you need, i dont know which ones these are so i put in some randoms.) 
                FROM user 
                WHERE user.userid = $userid
            "); 


may be better
