Manipulate Headers of PHP response in .htaccess-file?

Is it possible to add headers (defined in a .htaccess file) to a response generated by PHP?

I have the following .htaccess file in my that should add a Header TestHeader to each response delivered by my Apache Webserver:

#<IfModule mod_headers.c>
#  Header unset X-Powered-By
  Header add TestHeader "It works."
#</IfModule>

I also have three additional files in that folder:

  1. html.html

    <html>content</html>

  2. 1.php

    <?php
echo "<html>content php</html>";

  3. 2.php

    <?php
header("TestHeader: Sent from PHP.");
echo "<html>content php</html>";
    • Requesting html.html returns the header TestHeader: "It works."
    • Requesting 1.php does not return header TestHeader
    • Requesting 2.php returns the header TestHeader: "Sent from PHP."

Is it somehow possible to manipulate the response header from PHP output using .htaccess directives?

EDIT: PHP runs as FastCGI on the server.

This is likely to be a problem with your Apache version and the fact that PHP runs as FastCGI.

In Apache 2.2.X there was a bug: https://bz.apache.org/bugzilla/show_bug.cgi?id=49308

I found a couple of other posts that propose to use the always condition to fix the problem:

Header always add TestHeader "It works."

You can use SetEnvIf and then add the header accordingly:

SetEnvIf Request_URI "\.php$" phpfile
Header set TestHeader "Sent from PHP" env=phpfile

If the request URL ends with the extension ".php", then SetEnvIf will set a variable "phpfile". If the variable "phpfile" exists only then TestHeader: Sent from PHP will be sent as a response header. You can use this logic for as many extensions or URL patterns as you need.

Edit: If the header already exists i.e. it is sent from PHP, then using Header Set apache will replace it by the new value.
