This is a simple, convenient, and fully functional paging class. You can change the CSS style file according to your own needs to control the paging color. Using the PHP paging class, you can save yourself a lot of time. You only need to Just embed it somewhere. Here’s how to use it:
1. Include pager.css
<link href="pager.css" type="text/css" rel="stylesheet" />
in the head 2. Instantiate the class at the paging location:
<?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. Reading the mysql database and paging calculation files need to be written by yourself. For example:
$info=mysql_query("select * from member order by id desc limit $offset,$info_num"); In this way, the mysql database and current page number can be transferred.
The following are three files included in total: (1) index.php: call the paging class and display the paging (2) pager.class.php: php paging class (3) pager.css: css style beautification File
(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
