Type check MSOFFICE MIME

Question

I have the following:

$mimeTypes = array('application/msword'); //used to be an array $finfo = new finfo(FILEINFO_MIME, "/usr/share/misc/magic"); $type = $finfo->file($_FILES['userfile']['tmp_name']); $mime = substr($type, 0, strpos($type, ';')); if (in_array($mime, $mimeTypes)) { //let it in 

The problem is that I get "application / vnd.ms-office" as a file for any MSOFFICE file that I am trying to download. I DO NOT want to allow all MSOFFICE files, only .DOC. Is there a workaround for this?

** Please note that these files of type MSOFFICE were created in OPENOFFICE, will it matter?

Answer 1

The best you can do is check the file extension after you know that the file is an Office document ( application/vnd.ms-office ) and manually sets the correct MIME for the current file.

If you have access to Apache, you can add the correct MIME to conf/mime.types

 application/msword doc application/vnd.ms-excel xls [..] etc
