function.php页:
<?php

if(!$url){ $url=$_SERVER["REQUEST_URI"];}
//解析URI，获得数组形式传送给$parse_url
$parse_url=parse_url($url);
//$parse_url["query"],获得?后的变量
$url_query=$parse_url["query"];

$page=min($lastpg,$page);

//开始分页导航条代码：
$pagenav="显示第 <B>".($totle?($firstcount+1):0)."</B>-<B>".min($firstcount+$displaypg,$totle)."</B> 条记录，共 $totle 条记录";
//如果只有一页则跳出函数：
