PHP分页类的实现，返回结果未渲染，更容易在HTML中使用

给大家分享一个自己写的PHP分页类，使用方法简单，而且在网页中，结合Smarty可以实现很丰富的效果，例如滑动门、翻页照片等效果。想的到的就自己实现吧，这里把源码分享下。

  5  * $Page = new Page('PageIdentify' , Pagesize , RecordCount);
  6  * $Page -> CreateUriPara ();  返回参数数组，array['Prev'],array['ParaFirst'],array['ParaEnd'],array['Next']

117         
118     }
119 }
120 
121 ?>

使用方法：

$Page = new Page('PageIdentify' , Pagesize , RecordCount);
$array = $Page -> CreateUriPara (); //返回参数数组，array['Prev'],array['ParaFirst'],array['ParaEnd'],array['Next']

$array['Prev']:上一页；

$array['ParaFirst']:每段的第一页；

$array['ParaEnd']:每段的最后一页；

$array['Next']:下一页。
