这是一款简单，方便，功能齐全的分页类，可以根据自己的需要更改css样式文件以实现分页颜色的控制，利用php分页类，可以省去自己很多时间，只需要在分页的地方嵌入即可，下面看下使用方法：
1,在head里包含pager.css
<link href="pager.css" type="text/css" rel="stylesheet" />
2，在分页处进行类的实例化：
<?php
include "pager.class.php";
$currentpage=isset($_get['page'])?$_get['page']:1;
//die($currentpage);
$mypage=new pager(1300,intval($currentpage));
$pagestr= $mypage->getpagercontent();
//echo $pagestr;
$mypage=new pager(90,intval($currentpage));
$pagestr= $mypage->getpagercontent();
echo $pagestr;
?>
3，读取mysql数据库和分页计算文件需要自己写出来。例如：
$info=mysql_query("select * from member order by id desc limit $offset,$info_num"); 这样才能调到 mysql 数据库和当前页码等。
下面是一共包含的三个文件：(1) index.php：调用分页类，显示分页 (2) pager.class.php：php分页类 (3)pager.css：css样式美化文件
(1) index.php：
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<title>----分页演示-----</title>
<link href="pager.css" type="text/css" rel="stylesheet" />
</head>
<body>
<?php
include "pager.class.php";
$currentpage=isset($_get['page'])?$_get['page']:1;
//die($currentpage);
$mypage=new pager(1300,intval($currentpage));
$pagestr= $mypage->getpagercontent();
//echo $pagestr;
$mypage=new pager(90,intval($currentpage));
$pagestr= $mypage->getpagercontent();
echo $pagestr;
?>
</body>
</html>
(2) pager.class.php：
<?php
