16        Filter all fields and all rows in a recordset and returns the
17        processed recordset. We scroll to the beginning of the new recordset
18        after processing.
19
20        We pass a recordset and function name to RSFilter($rs,'rowfunc');
21        and the function will be called multiple times, once
22        for each row in the recordset. The function will be passed
23        an array containing one row repeatedly.
24
25        Example:
26
27        // ucwords() every element in the recordset
28        function do_ucwords(&$arr,$rs)
29        {
30                foreach($arr as $k => $v) {
31                        $arr[$k] = ucwords($v);
32                }
33        }
34        $rs = RSFilter($rs,'do_ucwords');

41                $rs = $rs->connection->_rs2rs($rs);
42        }
43        $rows = $rs->RecordCount();
44        for ($i=0; $i < $rows; $i++) {

47                $method = $fn[1];
48                $obj->$method ($rs->_array[$i],$rs);
49      } else {
50                        $fn($rs->_array[$i],$rs);
