So my questions:
1. How do you validate Word and Excel files before upload?
Before? JavaScript...if JavaScript can even do it (I haven't touched
the stuff in ages). After upload, you can check the mime type, but
that's not foolproof.
Okay, sorry I miswrote: after upload to the temp directory, BEFORE using
move_uploaded_file(). Checking the mime type is the problem - if I can't
trust the browsers am I really reliant on the file extension? Can't I
peek in some manner into it as we do with getimagesize()?
If your version of php has been configured with it, you can use
mime_content_type()
