/*
        Filter all fields and all rows in a recordset and returns the
        processed recordset. We scroll to the beginning of the new recordset
        after processing.

        We pass a recordset and function name to RSFilter($rs,'rowfunc');
        and the function will be called multiple times, once
        for each row in the recordset. The function will be passed
        an array containing one row repeatedly.

        Example:

        // ucwords() every element in the recordset
        function do_ucwords(&$arr,$rs)
        {
                foreach($arr as $k => $v) {
                        $arr[$k] = ucwords($v);
                }
        }
        $rs = RSFilter($rs,'do_ucwords');
 */
function RSFilter($rs,$fn)
{
        if ($rs->databaseType != 'array') {
                if (!$rs->connection) return false;

                $rs = $rs->connection->_rs2rs($rs);
        }
        $rows = $rs->RecordCount();
        for ($i=0; $i < $rows; $i++) {
                if (is_array ($fn)) {
                $obj = $fn[0];
                $method = $fn[1];
                $obj->$method ($rs->_array[$i],$rs);
      } else {
                        $fn($rs->_array[$i],$rs);
      }

        }
        if (!$rs->EOF) {
                $rs->_currentRow = 0;
                $rs->fields = $rs->_array[0];
        }

        return $rs;
