又花了半天时间写了个php上传类
刚学PHP没多久，为了更好的练习及熟悉PHP，自己花了大半天写了个php上传类，在这里做个笔记，欢迎朋友们对这个类做修改及优化。

- PHP code
//up_class.php
* $upFolder(保存到服务器的文件夹);
* $isRename(对上传文件重命名，值 有 y|n );
* $reType(上传成功后返回的值：n是返回文件名,pn:返回路径和文件名,j:返回js[待扩展]);
* $upExt(要上传的文件分类,因为在不同的表单要限制不同的上传文件类型，比如 A表单只能上传图片，B表单只能上伟压缩包);
* $maxSize(限制上传的文件大小)
* @author:256kb
