PHP How to disable the sending of headers?

The script sends:

HTTP/1.1 200 OK
Date: Tue, 08 Nov 2016 17:45:54 GMT
Server: Apache
X-Powered-By: PHP/5.4.9
Content-Length: 0
Keep-Alive: timeout=30, max=993
Connection: Keep-Alive
Content-Type: text/html

And rightly so. But is it possible to make sure that he didn't send headers at all without the connection.
exit - does not help

In fact, the header does not reflect the script and the web server. And he can not send headers because it supports the HTTP Protocol.
Without rewriting the web server that this behavior won't work.
And the client (if the browser), an internal timeout waiting for a response, sever the connection himself and he will request the page again.

But you can set your headers
header("HTTP/1.1 404 Not Found");
