mysql+php分頁類（已測）

複製代碼 代碼如下:<?php
/*
mysql_pager.class.php

三個參數。 mysql_query()的結果, url變數page, 您要的每頁記錄數
例子在這個檔案底部
淡水河邊整理測試
*/

class mysql_pager {
// define properties
var $page;
var $result;
var $results_per_page = 3;
var $total_pages;

/*
Define the methods

下面是建構函式，和類同名（>php4）
需要查詢的結果控制代碼，當前頁碼，每頁記錄數
like: $f->mysql_pager($result, 1, 15);
*/

下面是列印內容的函數，可以不用，也可以根據自己的需要擴充
這裡只是列印出id

// 編輯這部分輸出任何您想要的HTML

下面是列印頁碼和連結的函數
在我們需要顯示頁碼的地方調用
*/
