I saw someone asking for the Baidu paging class on the forum, so I posted the paging class a few weeks ago.
2.0 the relative 1.0 amendment is as follows:
1. support for PHP4 and PHP5
2. added the ajax paging function.
3. optimized the overall program structure
4. added the custom style feature.

The code is as follows:

The code is as follows:

* Description: exclusive paging mode. four paging modes are used by default, which are similar to baidu and google paging modes.
* 2.0 added: supports custom styles and styles, and supports both PHP4 and PHP5,
* To see detail, please visit [url = required?
* 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
'. $ Page-> show (3 );
Echo 'MoDe: 4
'. $ Page-> show (4 );
Enable AJAX:
$ Ajaxpage = new page (array ('total' => 1000, 'perpage' => 20, 'Ajax '=> 'Ajax _ page ', 'page _ name' => 'test '));
Echo 'MoDe: 1
'. $ Ajaxpage-> show ();
Use the inherited custom paging display mode:

Provides a simple demo

The code is as follows:

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 'start AJAX mode :';
$ Ajaxpage = new page (array ('total' => 1000, 'perpage' => 20, 'Ajax '=> 'Ajax _ page ', 'page _ name' => 'test '));
Echo 'MoDe: 1
'. $ Ajaxpage-> show ();
?>
