PHP+AJAX分页






#header("Content-Type:text/html;charset=GB2312");
$pagesize=10;
//echo $_POST['page'];
$db=mysql_connect("localhost","root",""); //创建数据库连接
mysql_query("set names gbk");
mysql_select_db("pagelist");
$result = mysql_query("select * FROM sheet1",$db);
$myrow = mysql_fetch_array($result);
$numrows=mysql_num_rows($result);
$pages=intval($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 sheet1 limit $offset,$pagesize");
$num = mysql_num_rows($result);
while ($row = mysql_fetch_array($result,$db)) {
$hotelname[] = $row[0];
$name[]=$row[1];
$author[]=$row[2];
$publisher[]=$row[3];
$isbn[]=$row[4];
$type[]=$row[5];
$smallpic[]=$row[6];
//$countpeople[] = $row[1];
}
