PHP上传类还是比较常用的，于是我研究了一下PHP上传类，在这里拿出来和大家分享一下，希望对大家有用。PHP本身是一种简单而强大的语言。PHP语言拥有核心特性如强大的字符串和数组处理能力，同时极大的改进了对面向对象编程的支持（PHP5以上版本）。
通过使用标准的和可选的扩展模块，PHP应用程序可以连接MySQL或Oracle等十几种数据库、绘图、创建PDF文件和创建解析XML文件。你也可以使用C语言来写自己的PHP扩展模块。例如，在已存在的代码库中提供一个PHP的接口函数。你也可以在Windows下运行PHP，使用COM控制其它诸如Word和Excel的Windows应用程序，或者使用ODBC来连接数据库。在国内，PHP曾经和微软的ASP并驾齐驱，是大家常用的网络编程语言。
