Downloads over PHP

We don’t understand “downloads with headers”. PHP headers?

Ok, but PHP headers to show what? HTTP headers? Like:

header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Transfer-Encoding: binary');
header('Connection: Keep-Alive');

You can do that with a page template.

You could link to a page template that only contains the headers you need and a link to the file, as you don’t want those headers on the main page template.

You can also force download files via mimetypes in .htaccess.
