2，分页类的示例一
<html>
<head>
<style type="text/css">
/* style for show*/
.pagination{direction:ltr}
.pagination a{border-radius:3px;background-color:#eee;color:#555;border:1px solid #aaaaaa;padding-top:2px;padding-bottom:2px;
padding-right:5px;padding-left:5px;text-decoration:none;}
.pagination a:hover ,.pagination .cur{border-color:#0C52CE;color:#0C52CE;background-color:#fff;}
</style>
<title>php分页类示例---www.</title>
</head>
<?php
//include class:
require_once"pagination.php";
//get the numbet of current page
//note! you should safe it
if(isset($_GET['page'])){
$page=$_GET['page'];
}
else $page=1;
//connect to db ...
mysql_connect("localhost","root","");//use your host,username and password to connect to the db
mysql_select_db("dbname");//select your database
//run query to get number of all records
$query=mysql_query("select count(id) from table"); //raplace table with your table name
$totall=mysql_result($query,0);
//creat new object
$pagination=new pagination($totall,3 /*number of content per page*/,$page,5 /*number of button to show*/);

//echo your result
while($row=mysql_fetch_assoc($SecondQuery))
{
echo 'id='.$row['id'].'<br>';
}
//show pagination:
$pagination->Show_Pagination("ExampleMysql.php?param1=value1",'page','pagination');

3，分页类的调用示例二
<html>
<head>
<style type="text/css">
/* style for show*/
.pagination{direction:ltr}
.pagination a{border-radius:3px;background-color:#eee;color:#555;border:1px solid #aaaaaa;padding-top:2px;padding-bottom:2px;
|padding-right:5px;padding-left:5px;text-decoration:none;}
.pagination a:hover ,.pagination .cur{border-color:#0C52CE;color:#0C52CE;background-color:#fff;}
</style>
<title>php分页类的调用示例-www.</title>
</head>
<?php
//include分页类文件
require_once "pagination.php";
//param of url to specify page_number
$get_param='page';
//get current page from url
$current_page=(isset($_GET[$get_param]) && is_numeric($_GET[$get_param]))?$_GET[$get_param]:1;
//notice: when get param , youe should SAFE it
//get totall available content
// for example you can get number of news from news table in database ( mysql_num_rows or count())
$totall_content=120; // for example
//creat new cat object
$cat=new pagination($totall_content,10 /*number of content per page*/,$current_page,5 /*number of button*/);
//when you want to load content of page: for example in db queris :
// select * from table where conditions order by key limit $cat->Start , $cat->End
//for show :
$cat->Show_Pagination("example.php?",'page','pagination');

<form action="/blog_article/</php echo $_SERVER[.html'PHP_SELF']; //safe it later (xss)?>" method="post">
<a>INPUT TEXT :</a><br>
