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 */
36function &RSFilter($rs,$fn)
37{
38    if ($rs->databaseType != 'array') {
39        if (!$rs->connection) return false;
40       
41        $rs = &$rs->connection->_rs2rs($rs);
42    }
43    $rows = $rs->RecordCount();
44    for ($i=0; $i < $rows; $i++) {
45        if (is_array ($fn)) {
46            $obj = $fn[0];
47            $method = $fn[1];
48            $obj->$method ($rs->_array[$i],$rs);

56        $rs->fields = $rs->_array[0];
