Αυτο δεν χρειάζεται λογικά. Το $_FILES["file"]["type"] περιέχει από μόνο του το mime type.

 

Από το http://www.php.net/manual/en/features.file-upload.post-method.php

$_FILES['userfile']['type']

 

The mime type of the file, if the browser provided this information. An example would be "image/gif".
