PHP xls, xlsx, ppt, pptx headers

Question

Here is my code where I am trying to send a correct header depedning on a type of a document. I figured out the headers for pdf, doc and docx but I still need to know correct he

Answer 1

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

Answer 2

You can simply echo $_FILES['input_tag_name']['type'] after upload a file to know the MIME type of that file.

Answer 3

.xls

application/vnd.ms-excel

.xlsx

application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

.ppt

application/vnd.ms-powerpoint

.pptx

application/vnd.openxmlformats-officedocument.presentationml.presentation

And one of those you have listed is wrong:

.docx

application/vnd.openxmlformats-officedocument.wordprocessingml.document

Answer 4

See http://www.w3schools.com/media/media_mimeref.asp .

xls is application/vnd.ms-excel, ppt is application/vnd.ms-powerpoint.
