示例1: paginate
public function paginate($page = 1, $where = array(), $limit = 10)
{
// get filtered results
$where = array_merge($where, $this->where);
$offset = $page <= 1 ? 0 : ($page - 1) * $limit;
$this->db->limit($limit, $offset);
$results = parent::get_many_by($where);
// get counts (e.g. for pagination)
$count_results = count($results);
$count_total = parent::count_by($where);
$total_pages = ceil($count_total / $limit);
$counts = array('from_num' => $count_results == 0 ? 0 : $offset + 1, 'to_num' => $count_results == 0 ? 0 : $offset + $count_results, 'total_num' => $count_total, 'curr_page' => $page, 'total_pages' => $count_results == 0 ? 1 : $total_pages, 'limit' => $limit);
return array('data' => $results, 'counts' => $counts);

}
// avoid overrided by $this->limit

// get filtered results
