Not a worry, I worked it out after reading your post anyway

PHP Code:

                                else
                {
                    $vartype -= TYPE_CONVERT_SINGLE;
                }
 
                foreach (array_keys($var) AS $key)
                {
                    $this->do_clean($var["$key"], $vartype);
                } 


I didnt realise the array types were identical (just +100) to the single types.
