前段时间发了一个PHP分页的,后来研究了下多列的,今天再发上去
<?php require_once('Connections/lr.php'); ?>
<?php require_once('pageconfig.php'); ?>
<?php
//设定每一页显示的记录数
$pagesize=$meiyegeshu;
//取得记录总数$rs,计算总页数用
mysql_select_db($database_lr, $lr);
$rs=mysql_query("select count(*) from product");
$myrow = mysql_fetch_array($rs);
$numrows=$myrow[0];
//计算总页数
$pages=intval($numrows/$pagesize);
if ($numrows%$pagesize)
$pages++;
//设置页数
if (isset($_GET['page'])){
$page=intval($_GET['page']);
}
else{
//设置为第一页
$page=1;
}
//计算记录偏移量
$offset=$pagesize*($page - 1);
//读取指定记录数
$rs=mysql_query("select * from product order by articleid limit $offset,$pagesize");
if ($myrow = mysql_fetch_array($rs))
{
$i=0;
//如果$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"]; //单独取出URL的查询字串
if($url_query){
//因为URL中可能包含了页码信息,我们要把它去掉,以便加入新的页码信息。
//这里用到了正则表达式,请参考“PHP中的正规表达式”(http://www.pconline.com.cn/pcedu/empolder/wz/php/10111/15058.html)
$url_query=ereg_replace("(^|&)page=$page","",$url_query);
//将处理后的URL的查询字串替换原来的URL的查询字串:
$url=str_replace($parse_url["query"],$url_query,$url);
//在URL后加page查询信息,但待赋值:
if($url_query) $url.="&page"; else $url.="page";
}else {
$url.="?page";
}

用到了几个变量,分别是$meiyegeshu,$meihanggeshu读拼音就知道是什么了,呵呵。
