代码,php分页函数。
复制代码 代码如下:
/*
* Created on 2011-07-28
* Author : LKK , http://lianq.net
* 使用方法:
require_once('mypage.php');
$result=mysql_query("select * from mytable", $myconn);
$total=mysql_num_rows($result); //取得信息总数
pageDivide($total,10); //调用分页函数
//数据库操作
$result=mysql_query("select * from mytable limit $sqlfirst,$shownu", $myconn);
while($row=mysql_fetch_array($result)){
...您的操作
}
echo $pagecon; //输出分页导航内容
*/
if(!function_exists("pageDivide")){
#$total 信息总数
#$shownu 显示数量,默认20
#$url 本页链接
function pageDivide($total,$shownu=20,$url=''){
#$page 当前页码
#$sqlfirst mysql数据库起始项
#$pagecon 分页导航内容
global $page,$sqlfirst,$pagecon,$_SERVER;
$GLOBALS["shownu"]=$shownu;
if(isset($_GET['page'])){
$page=$_GET['page'];
}else $page=1;
#如果$url使用默认,即空值,则赋值为本页URL
if(!$url){ $url=$_SERVER["REQUEST_URI"];}
#URL分析
$parse_url=parse_url($url);
@$url_query=$parse_url["query"]; //取出在问号?之后内容
if($url_query){
$url_query=preg_replace("/(&?)(page=$page)/","",$url_query);
$url = str_replace($parse_url["query"],$url_query,$url);
if($url_query){
$url .= "&page";
}else $url .= "page";
}else $url .= "?page";
#页码计算
$lastpg=ceil($total/$shownu); //最后页,总页数
$page=min($lastpg,$page);
$prepg=$page-1; //上一页
$nextpg=($page==$lastpg ? 0 : $page+1); //下一页
$sqlfirst=($page-1)*$shownu;
#开始分页导航内容
$pagecon = "显示第 ".($total?($sqlfirst+1):0)."-".min($sqlfirst+$shownu,$total)." 条记录,共 $total 条记录";
if($lastpg
if($page!=1) $pagecon .=" 首页 "; else $pagecon .=" 首页 ";
if($prepg) $pagecon .=" 前页 "; else $pagecon .=" 前页 ";
if($nextpg) $pagecon .=" 后页 "; else $pagecon .=" 后页 ";
if($page!=$lastpg) $pagecon.=" 尾页 "; else $pagecon .=" 尾页 ";
#下拉跳转列表,循环列出所有页码
$pagecon .=" 到第 页,共 $lastpg 页";
}
}else die('pageDivide()同名函数已经存在!');
