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');
35  */

38  if ($rs->databaseType != 'array') {
39  if (!$rs->connection) return false;
40 
41  $rs = $rs->connection->_rs2rs($rs);
42  }
43  $rows = $rs->RecordCount();

45  if (is_array ($fn)) {
46  $obj = $fn[0];
47  $method = $fn[1];
48  $obj->$method ($rs->_array[$i],$rs);
