I have a problem uploading a file in IE6 or Firefox1.0 but it works
fine using Opera7.54.

The problem is that I want to ensure that the file being uploaded is a
CSV file, so I test the $_FILES['file']['type'] value.

In Firefox & IE it is returned as "application/octet-stream" but in
Opera it is returned as "text/comma-separated-values", the latter
being what I would expect.

The posting form has: enctype="multipart/form-data"

Can anyone offer some advice on how I can reliably test for a valid CSV file?

(At least I have some security built-in, in so much as you have to use
Opera to upload files !!)
