PHP分页函数代码（简单实用型）_php

复制代码 代码如下:

<?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 .= “<a href=”?page=1″>首页</a> “;
$pagenav .= “<a href=”?page=$pre_page”>前一页</a> “;
$pagenav .= “<a href=”?page=$next_page”>后一页</a> “;
$pagenav .= “<a href=”?page=$page_count”>末页</a>”;
$pagenav.=”　跳到<select name=”topage” size=”1″ ?page=/”+this.value”>/n”;
for($i=1;$i<=$page_count;$i++){
if($i==$page) $pagenav.=”<option value=”$i” selected>$i</option>/n”;
else $pagenav.=”<option value=”$i”>$i</option>/n”;
}
} // Page分页函数
// 使用示例
if (!$conn= mysql_connect(“localhost”, “root” ,”root”)) die(“数据库选择失败！”);
if (!mysql_select_db(“test”, $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
$rows = mysql_num_rows(mysql_query(“select * from test”));
Page($rows,2);
$sql = “select * from test limit $select_from $select_limit”;
$rst = mysql_query($sql);
while ($row = mysql_fetch_array($rst)){
echo “$row[id] – $row[sex] – $row[name] <hr />”;
}
echo $pagenav;
?>
