PHP学习笔记12-上传文件

enctype介绍：enctype属性指定将数据发回到服务器时浏览器使用的编码类型。

取值说明：

https://www.gxlcms.com/multipart/form-data： 窗体数据被编码为一条消息，页上的每个控件对应消息中的一个部分，不对字符编码。当使用有文件上传控件的表单时，该值是必需的。。
https://www.gxlcms.com/application/x-www-form-urlencoded： 窗体数据被编码为名称/值对。这是标准的编码格式。在发送前对所有字符进行编码（默认）。
https://www.gxlcms.com/text/plain： 窗体数据以纯文本形式进行编码，其中不含任何控件或格式字符，邮件处理中用到，其他地方很少用。将空格转换为 "+" 符号，但不编码特殊字符。抓包可见数据形式。
