php 文件上传后缀名与文件类型对照表(几乎涵盖所有文件)

网上有很多php文件上传的类，文件上传处理是php的一个特色(至少手册上是将此作为php特点来展示的,个人认为php在数组方面的优异功能更有特色)，学php的人都知道文件上传怎么做，但很多人在编程中却可能忽视了一些细节问题，那就是文件的类型(MIME)。在表单将文件提交给php做处理之前，浏览器会先解析识别一边是什么类型的文件，之后进入php处理环节，php又会去识别解析此文件的原始类型(并不是说你改成什么后缀就是什么文件)。在这个过程中会有一些浏览器兼容，更准确来说是文件类型解析标识不一致的问题。这样在php处理Post过来的文件类型时就需要根据不同浏览器做更多的判断，最典型的就是IE和火狐下的区别。
