移动文件出错！
------解决方案--------------------
没设置允许上传的权限吧，说你mkdir()被拒，有extension未打开
------解决方案--------------------
notice: use of undefined constant tmp_name
注意：使用了没有定义的常量 tmp_name
解决方法： 给它加上'tmp_name' 引号。或者可以通过设置php.ini关闭notice错误级别(就可以使用[tmp_name]了)。
warning: mkdir() [function.mkdir]: permission denied
警告： 访问被拒绝。请确认对当前目录有权限。
failed to open stream: no such file or directory
请检查路径是否有问题。
