    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

复制代码 代码如下:

    <link href="pager.css" type="text/css" rel="stylesheet" />

    2,在分页处进行类的实例化:

复制代码 代码如下:

<?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:

复制代码 代码如下:

<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:

复制代码 代码如下:

<?php
