Since most of the types requested are Microsoft Office related, this link has all of the office mime types (the best focused source I've found so far): http://filext.com/faq/office_mime_types.php
由于请求的大多数类型与 Microsoft Office 相关，因此此链接包含所有办公室 mime 类型（迄今为止我找到的最集中的来源）：http: //fileext.com/faq/office_mime_types.php

You can simply echo $_FILES['input_tag_name']['type'] after upload a file to know the MIME type of that file.
您可以在上传文件后简单地 echo $_FILES['input_tag_name']['type'] 以了解该文件的 MIME 类型。
