2，php分頁類別的使用方法：
 

header('content-type:text/html;charset=utf-8');
include('Page.class.php') ;
$page_all_no = 12000; //資料的總條數
$page_num = 25; //設定每頁顯示的條數
$page_len = 7; //顯示最多的頁碼數
$page = new Page($page_all_no, $page_num, $page_len);
$start_num = $page->start_num;
$sql = "select * from table limit {$start_num}, {$page_num} ";
$page->key_change_page(); //方向鍵翻頁
var_dump($sql);
//自帶三種分頁形式，可再按需要新增方法，像下面那樣呼叫
echo ''.$page->select_page('self', 'NORMAL').''; //這裡的第二個參數預設為PMA模式，兩種模式差異在上面已給出
echo ''.$page->eshow().'';
echo ''.$page->show().' ';
