精美漂亮的php分页类代码

2013-04-02 00:00 941 查看
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    
/*

 * @Modify  2013-03-27
