    3. include('Page.class.php') ;
    4. $page_all_no = 12000; //資料的總條數
    5. $page_num = 25; //設定每頁顯示的條數
    6. $page_len = 7; //顯示最多的頁碼數
    7. $page = new Page($page_all_no, $page_num, $page_len);
    8. $start_num = $page->start_num;
    9. $sql = "select * from table limit {$start_num}, {$page_num} ";
    10. $page->key_change_page(); //方向鍵翻頁
    11. var_dump($sql);
    12. //自帶三種分頁形式，可再按需要新增方法，像下面那樣呼叫
    13. echo '

      '.$page->select_page('self', 'NORMAL').'

      '; //這裡的第二個參數預設為PMA模式，兩種模式差異在上面已給出
