php利用模板分页程序

这是一款比较经典的php分页代码,利用了程序模板,页面分离的方式来做这个文件分页功能,实在是太牛了,实例代码如下.

page.class.php:

1. class page{ 
2.  
3.  var $currentpage; 
4.  var $leftoffset; 
5.  var $rightoffset; 
6.      
7.  var $totalpage;//总页数 
8.  var $recordcount;//总记录数 
9.  var $pagesize;//每页显示条数 
10.  
11.  var $pageurl; 
12.  var $hypelink; 
13.  
14.  var $template; 
15.  var $tpl; 
16.  var $tagitems=array(); 
17.  var $tagvalues=array(); 
18.  
19.  var $sqlquery; 
20.  
21.  //构造函数 
22.  function page($currentpage=1,$pagesize=5,$leftoffset=2,$rightoffset=7,$pageurl="?page="){
