PHP Code:

if (!functions_exists('array_intersect_key') {
function array_intersect_key() {
   $numArgs = func_num_args();
   if (2 <= $numArgs) {
       $arrays =& func_get_args();
       for ($idx = 0; $idx < $numArgs; $idx++) {
           if (! is_array($arrays[$idx])) {
               trigger_error('Parameter ' . ($idx+1) . ' is not an array', E_USER_ERROR);
               return false;
           }
       }

       foreach ($arrays[0] as $key => $val) {
           for ($idx = 1; $idx < $numArgs; $idx++) {
               if (! array_key_exists($key, $arrays[$idx])) {
                   unset($arrays[0][$key]);
               }
           }
       }

       return $arrays[0];
   }

   trigger_error('Not enough parameters; two arrays expected', E_USER_ERROR);
   return false;
}
}

$forum = fetch_foruminfo($forumid);

$forum['allowbbcode'] = false;

$forumoptions = convert_array_to_bits(array_intersect_key($forum, $_FORUMOPTIONS), $_FORUMOPTIONS);

$DB_site->query("UPDATE " . TABLE_PREFIX . "forum SET options=$forumoptions WHERE forumid=$forumid"); 


But I think it is by far easier to just execute a query which directly changes what you want to change:

now im making a script that will make same options to all of forums
that their teamid !=0 so if ill do allow html
its will edit all forums that their teamid !=0

[sql]UPDATE forum SET options=options+256 WHERE teamid != 0 AND NOT (options&256)[/sql]

Don't forget to call build_forum_permissions() afterwards.
