- * Description: Paging class, four paging modes
- * 2.0 added Features: Support custom style, custom style, support PHP4 and PHP5,
- * To see Detail,please visit http://www.phpobject.net/blog/read.php?
- * 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);
- Turn on Ajax:
- $ajaxpage =new page (Array (' Total ' =>1000, ' perpage ' =>20, ' ajax ' = ' ajax_page ', ' page_name ' = ' test '));
- Echo ' Mode:1
'. $ajaxpage->show ();
- Adopt the inherited custom paging display mode:
