Class DibiResultIterator

External result set iterator.

This can be returned by DibiResult::getIterator() method or using foreach

  1. 1:  $result = dibi::query('SELECT * FROM table');
  2. 2:  foreach ($result as $row) {
  3. 3:     print_r($row);
  4. 4:  }
  5. 5:  unset($result);

Optionally you can specify offset and limit:

  1. 1:  foreach ($result->getIterator(2, 3) as $row) {
  2. 2:      print_r($row);
  3. 3:  }
