How to get MIME type of a file in PHP 5.5?

Question

I am using mime_content_type() in PHP 5.5 to get a MIME type, but it throws fatal: error function not found.

How can I achieve this on PHP

Answer 1

mime_content_type() is not deprecated and works fine.

Why is mime_content_type() deprecated in PHP?

As of PHP 5.3, it's even built-in.
