程式碼如下：
<?php
require_once('conn.php'); //連接數(shù)據(jù)庫
require_once('functions.php');
$page=isset($_GET['page']) ?$_GET['page'] :1 ;//接收頁碼
$page=!empty($page) ? $page :1;
$table_name="news";//查取表名設(shè)置
$perpage=1;//每頁顯示的數(shù)據(jù)個數(shù)
//最大頁數(shù)和總記錄數(shù)
$total_sql="SELECT count(*) from $table_name";
$total_result =mysql_query($total_sql);
$total_row=mysql_fetch_row($total_result);
$total = $total_row[0];//獲取最大頁碼數(shù)
$total_page = ceil($total/$perpage);//向上整數(shù)
//臨界點(diǎn)
$page=$page>$total_page ? $total_page:$page;//當(dāng)下一頁數(shù)大于最大頁數(shù)時的情況
//分頁設(shè)置初始化
$start=($page-1)*$perpage;
$sql = "SELECT * from news order by id desc limit $start,$perpage";
$info = mysql_query($sql);
?>
