網上有很多php文件上傳的類，文件上傳處理是php的一個特色(至少手冊上是將此作為php特點來展示的,個人認為php在數組方面的優異功能更有特色)，學php的人都知道文件上傳怎麼做，但很多人在編程中卻可能忽視了一些細節問題，那就是文件的類型(MIME)。在表單將文件提交給php做處理之前，浏覽器會先解析識別一邊是什麼類型的文件，之後進入php處理環節，php又會去識別解析此文件的原始類型(並不是說你改成什麼後綴就是什麼文件)。在這個過程中會有一些浏覽器兼容，更准確來說是文件類型解析標識不一致的問題。這樣在php處理Post過來的文件類型時就需要根據不同浏覽器做更多的判斷，最典型的就是IE和火狐下的區別。
