  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   */
  36  function &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);
  49        } else {
  50              $fn($rs->_array[$i],$rs);
  51        }
  52        
  53      }
  54      if (!$rs->EOF) {
  55          $rs->_currentRow = 0;
  56          $rs->fields = $rs->_array[0];
