使用文本數據庫一般是針對小型的應用程序了，這種不就需要安裝數據庫了，我們可以直接操作文本文件就可以了，但時怎麼操作都不如mysql數據庫好用了，下面我來給大家介紹一個文本數據庫轉為mysql數據庫實例。
代碼如下

<?php
require_once 'config.php';
$action = empty($_GET['action']) ? '' : $_GET['action'];
$id = isset($_GET['id']) ? $_GET['id'] : 0;

$page = isset($_GET['page']) ? intval($_GET['page']) : 1;
$page = ($page =='' && $page < 0) ? 1 : $page;
$total = mysql_num_rows(mysql_query($result));//數據條目總數
$pageall = ceil($total/$items);
$offset = ($page-1)*$items;//數據開始位置
$result .= " limit {$offset},{$items}";//每頁顯示
$results = mysql_query($result);
