Super paging class 2.0 is released, supports custom styles, and has 4 default display modes

2.0 has been revised relative to 1.0 as follows:
1. Supports PHP4 and PHP5
2. Added ajax paging function
3. Optimized the overall structure of the program
4. Added custom style The function

code is as follows:

* to see detail,please visit [url=http://www.phpobject.net/blog/read. php]http://www.phpobject.net/blog/read.php[/url]?
* example:
* Mode four paging modes:
require_once('../libs/classes /page.class.php');
$page=new page(array('total'=>1000,'perpage'=>20));
echo 'mode:1
' .$page->show();
echo '

---

mode:2
'.$page->show(2);
echo '

---

mode:3< br>'.$page->show(3);
echo '

---

mode:4
'.$page->show(4);
Turn on AJAX:
$ajaxpage=new page(array('total'=>1000,'perpage'=>20,'ajax'=>'ajax_page','page_name'=>'test'));
echo 'mode:1
'.$ajaxpage->show();
Adopt inherited custom paging display mode:

提供一个简单的演示demo

复制代码 代码如下:

require_once('../libs/classes/page.class.php'); 
$page=new page(array('total'=>1000,'perpage'=>20)); 
echo 'mode:1
'.$page->show(); 
echo '

---

mode:2
'.$page->show(2); 
echo '

---

mode:3
'.$page->show(3); 
echo '

---

mode:4
'.$page->show(4); 
echo '

---

开始AJAX模式:'; 
$ajaxpage=new page(array('total'=>1000,'perpage'=>20,'ajax'=>'ajax_page','page_name'=>'test')); 
echo 'mode:1
'.$ajaxpage->show(); 
?>
