计算分页中的行数并显示它？

Question

我在其中使用了 codeigniter 和类 (library) pagination。
为什么此代码不适用于分页中的计数行，例如：

现有行：4 ->显示第 1 至 4 条，共 9 条

或

现有行：4 ->显示第 4 至 8 个，共 9 个

或

现有行：1 ->显示第 8 到 9 个，共 9 个

以及

其他

$this->load->library('pagination');
    //$this->load->library('Jquery_pagination');
    $config['base_url'] = base_url().'admin/accommodation/show';
    $config['uri_segment'] = 4;
    $config['total_rows'] = $this->db->count_all('hotel_submits');
    $config['per_page'] = '4';
    //$config['div'] = '#num_count'; /* Here #content is the CSS selector for target DIV */
    $config['num_links'] = 10000;
    $config['full_tag_open'] = '<div id="pagination">';
    $config['full_tag_close'] = '</div>';

    $this->pagination->initialize($config);

    $offset = (int) $offset; // just to make sure nothing funky gets in here
    $data['results'] = $this->db->query("SELECT @rownum:=@rownum+1 rownum, t.*
    FROM (
        SELECT *
        FROM hotel_submits
        ORDER BY id desc
        LIMIT $offset, 4    
    ) t,
    (SELECT @rownum:=0) r");

$curr_offset = $this->uri->segment($config['uri_segment']);
        $info = 'Showing ' . ( $curr_offset + 1 ) . ' to ' ;

        if( ( $curr_offset + $config['per_page'] ) < ( $config['total_rows'] -1 ) )
            $info = $curr_offset + $config['per_page'];
        else
            $info = $config['total_rows'];

        $info = ' of ' . $config['total_rows'] . ' | ';

        $data['num_count'] = $info;

$this->load->view('admin/accommodation_submit_show', $data);

此代码的输出是：of 9 |
