How do i get only the first part of the MIME type in PHP

Question

I would only like to know if a file is an image, a video or another type of file. The file does not exist on the server, as it is being uploaded.

Is there a way to get this in PHP?

Thank you

Answer 1

$mime = explode('/', mime_content_type($physicalPathForTheFile));
$type = $mime[0];
