How to prevent Content-Type header from being added by web servers

Question

I have a PHP script setting the Content-Type header to an empty value:

header('Content-Type: ');

This prevents nginx and Apache2 from setting the header, but the PHP development server sends the header even though it is empty.

I would like to know the best way to prevent this header from being added by web servers when the body of the response message is empty.

Thank you!

Answer 1

Maybe header_remove ?

header_remove('Content-Type');
