更郁闷的是，居然有三个空函数~~
上面的是我发的，第一次忘记加格式了，汗一个~~
我可以这么说
楼主的代码会造成SEO问题
在GOOGLE上，楼主的代码因为有了错误处理，当有人错误输入页数时，楼主的代码将其引向同一页面，这在搜索引擎上就叫重复内容，会让站点遭受惩罚。最好的办法，就是发送http/1.1 404 报头。
楼主的代码实在让人头晕，不过貌似楼主是把内容显示也加入进去了吧？
我认为这样做不好，不利于代码重用。因为如果别的页面也要分页，那么这个代码就用不上了
我写的那个是可以从不同的表，搜索不同的记录，每页显示的记录数也是可以改变的，其实很简单的了，随便想一下大家都能做出来，而且记录是返回给一个数组，这样，我们就可以再外部操作这个记录集，让他以与页面和谐的格式显示~~
说这么多不知道楼主有几点没想到，也许都想到了反正代码我是头太晕没看~_~!
本人比较菜，没怎么写过程序
笑我的人我晚上扒他们家窗户~
一个分页
至于弄的这么.........
一个limit
一个for语句不就搞定了吗
