他的特点:单纯,接受参数,给出分页;灵活:可以自己决定,上、下一页的名称(比如我想叫prev、nex t诸如此类)可以决定每页展示的分页数量,跨页数提供一个包装方法,适应不同的网页结构,比如有的网页我需要每个分页包含一个li(
1
...),依次类推备注说明:提供的示范代码中有两个静态方法大家可以不必理会。这个是自己项目开发用的。Call::import,大家可以使用include代 替URL::refresh,这是地址操作类,这里暂时不做说明,以后有机会再放上来,大家可以用这个页面的方法getUrl()http://www.oschin a.net/code/snippet_182375_6242

使用示范
- $pages = new Pages(100, 20);
- $pages->warp('|');
