  18         Filter all fields and all rows in a recordset and returns the
  19         processed recordset. We scroll to the beginning of the new recordset
  20         after processing.
  21
  22         We pass a recordset and function name to RSFilter($rs,'rowfunc');
  23         and the function will be called multiple times, once
  24         for each row in the recordset. The function will be passed
  25         an array containing one row repeatedly.
  26
  27         Example:
  28
  29         // ucwords() every element in the recordset
  30         function do_ucwords(&$arr,$rs)
  31         {
  32                 foreach($arr as $k => $v) {
  33                         $arr[$k] = ucwords($v);
  34                 }
  35         }
  36         $rs = RSFilter($rs,'do_ucwords');
  37  */

  41                 if (!$rs->connection) return false;
  42
  43                 $rs = $rs->connection->_rs2rs($rs);
  44         }
  45         $rows = $rs->RecordCount();
  46         for ($i=0; $i < $rows; $i++) {

  50                 $obj->$method ($rs->_array[$i],$rs);
  51       } else {
