For this script, it checks to see if the file is a microsoft words doc or ppt. I am not sure why this isn't running because it works for image MIME and text/plain.

I am using PHP 5.3.1 so it should have all the MIME types installed already right?

I am uploading words and powerpoint 2007.

//Does the file have the right MIME type?
if ($_FILES['userfile']['type'] !='application/msword') {
    echo 'Problem: file is not words doc.';
    exit;
}
