* description:超强分页类,四种分页模式,默认采用类似baidu,google的分页风格。
* 2.0增加功能:支持自定义风格,自定义样式,同时支持PHP4和PHP5,
* to see detail,please visit http://www.bKjia.c0m * example:
* 模式四种分页模式:
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);
开启AJAX:
$ajaxpage=new page(array('total'=>1000,'perpage'=>20,'ajax'=>'ajax_page','page_name'=>'test'));
echo 'mode:1 '.$ajaxpage->show();
采用继承自定义分页显示模式:
