代码如下：

<?php
    require_once('conn.php'); //连接数据库
    require_once('functions.php');
    $page=isset($_GET['page']) ?$_GET['page'] :1 ;//接收页码
    $page=!empty($page) ? $page :1;
    $table_name="news";//查取表名设置
    $perpage=1;//每页显示的数据个数
    //最大页数和总记录数
    $total_sql="SELECT count(*) from $table_name";
    $total_result =mysql_query($total_sql);
    $total_row=mysql_fetch_row($total_result);
    $total = $total_row[0];//获取最大页码数
    $total_page = ceil($total/$perpage);//向上整数
    //临界点
    $page=$page>$total_page ? $total_page:$page;//当下一页数大于最大页数时的情况
    //分页设置初始化
    $start=($page-1)*$perpage;
    $sql = "SELECT * from news order by id desc limit $start,$perpage";
    $info = mysql_query($sql);
