<?php
// Page分页函数
$page = $_GET["page"];

function Page($rows,$page_size){
global $page,$select_from,$select_limit,$pagenav;
$page_count = ceil($rows/$page_size);
if($page <= 1 || $page == '') $page = 1;
if($page >= $page_count) $page = $page_count;
$select_limit = $page_size;
$select_from = ($page - 1) * $page_size.',';
$pre_page = ($page == 1)? 1 : $page - 1;
$next_page= ($page == $page_count)? $page_count : $page + 1 ;
$pagenav .= "第 $page/$page_count 页 共 $rows 条记录 ";
$pagenav .= "首页 ";
$pagenav .= "前一页 ";
$pagenav .= "后一页 ";
$pagenav .= "末页";
$pagenav.="　跳到\n";
for($i=1;$i<=$page_count;$i++){
if($i==$page) $pagenav.="$i\n";
else $pagenav.="$i\n";
}
} // Page分页函数
// 使用示例
if (!$conn= mysql_connect("localhost", "root" ,"")) die('数据库选择失败！');
if (!mysql_select_db("dzsw", $conn)) die('数据库选择失败！');
mysql_query('set names GBK');
// 用Page函数计算出 $select_from 从哪条记录开始检索、$pagenav 输出分页导航
$rows = mysql_num_rows(mysql_query("select * from shop"));
Page($rows,2);
$sql = "select * from shop limit $select_from $select_limit";
$rst = mysql_query($sql);
echo "-----------名称------------------- 价格 --------------- 数量-------订购数量--------加入购物车

---

";
while ($row = mysql_fetch_array($rst)){

echo "-----------$row[mingcheng]--------------------$row[jiage] --------------------$row[shuliang]------订购数量：-----

'\" value='购买' class='submit'>

---

";
}
echo $pagenav;

?>
