使用文本数据库一般是针对小型的应用程序了,这种不就需要安装数据库了,我们可以直接操作文本文件就可以了,但时怎么操作都不如mysql数据库好用了,下面我来给大家介绍一个文本数据库转为mysql数据库实例,代码如下: <?php require_once 'config.php'; $action = emptyempty($_GET['action']) ? '' : $_GET['action']; $id = isset($_GET['id']) ? $_GET['id'] : 0; if (emptyempty($action)) {//列表 $result = "SELECT * FROM posts ORDER BY pid DESC"; $items = 3; $page = isset($_GET['page']) ? intval($_GET['page']) : 1; $page = ($page =='' && $page < 0) ? 1 : $page; $total = mysql_num_rows(mysql_query($result));//数据条目总数 $pageall = ceil($total/$items); $offset = ($page-1)*$items;//数据开始位置 $result .= " limit {$offset},{$items}";//每页显示 $results = mysql_query($result); $prev = $page - 1; $next = $page + 1; $goPrev = "<a href="?page=$prev">上一页</a>"; $goNext = "<a href="?page=$next">下一页</a>"; if ($page == $pageall){ $goNext = NULL;} $pagestate = ''; if ($page == 1 && $pageall > 1) { $pagestate .= $goNext; } elseif ($pageall > $page || $page >1) { $pagestate .= $goNext .
