对于PHP和Ajax分页显示数据库记录，网络上有多种方法，如服务器端只返回数据，其样式在客户端设置；或者在服务器端将样式与数据一起返回。本实例为了代码的安全起见，这里使用了第二种方法实现。
服务器端文件Example8_7_1.php.
<?php
header("Content-Type:text/html;charset=GB2312");
$pagesize=3;
//echo $_POST['page'];
$db=mysql_connect("localhost","root","111111");           //创建数据库连接
mysql_query("set character set gbk");
mysql_select_db("student");
$result = mysql_query("Select count(DISTINCT id) FROM ".book);
$myrow = mysql_fetch_array($result);
$numrows=$myrow[0];
$pages=intval($numrows/$pagesize);
if ($numrows%$pagesize)
$pages++;
if (isset($_POST['page'])){
$page=intval($_POST['page']);
}
else{
//设置为第一页
$page=1;
}
$first=1;
$prev=$page-1;
$next=$page+1;
$last=$pages;
//计算记录偏移量
$offset=$pagesize*($page - 1);
//读取指定记录数
            
//$result=mysql_query("select `id` , count( * ) from ".book." GROUP BY `id` order by id desc limit $offset,$pagesize");
$result=mysql_query("select * from ".book." GROUP BY `id` order by id desc limit $offset,$pagesize");
$num = mysql_num_rows($result);

while ($row = mysql_fetch_array($result,MYSQL_NUM)) {
$hotelname[] = $row[0];
$name[]=$row[1];
$author[]=$row[2];
$publisher[]=$row[3];
$isbn[]=$row[4];
$type[]=$row[5];
$price[]=$row[6];
//$countpeople[] = $row[1];
}
