This function doesn't exist on lighttpd, so I wrote this little function to emulate it:
<?php
if (!function_exists('apache_response_headers')) {
function apache_response_headers () {
$arh = array();
$headers = headers_list();
foreach ($headers as $header) {
$header = explode(":", $header);
$arh[array_shift($header)] = trim(implode(":", $header));
}
return $arh;
}
}
?>
apache_response_headers
(PHP 4 >= 4.3.0, PHP 5, PHP 7, PHP 8)
apache_response_headers — Fetch all HTTP response headers
Description
Fetch all HTTP response headers. Works in the Apache, FastCGI, CLI, and FPM webservers.
Parameters
This function has no parameters.
Return Values
An array of all Apache response headers on success or false on failure.
Examples
Example #1 apache_response_headers() example
<?php
print_r(apache_response_headers());
?>The above example will output something similar to:
Array
(
[Accept-Ranges] => bytes
[X-Powered-By] => PHP/4.3.8
)
See Also
- apache_request_headers() - Fetch all HTTP request headers
- headers_sent() - Checks if or where headers have been sent
- headers_list() - Returns a list of response headers sent (or ready to send)

I get "Call to undefined function apache_response_headers()" when using php-cli so be aware of lack of this function CLI.
In my case I was trying to test my app via phpunit (command line tool of course ;)) if it sends proper headers.

If apache_response_headers() returns an empty array, try calling flush() before and it'll get filled.

For apache_response_headers() working good, you need to set up output_buffering = Off in php.ini

Addendum: The code
<pre>
<?php
print_r(apache_request_headers());
?>
</pre>
gives me
Array
(
[X-Powered-By] => PHP/5.1.6
)
But the code
<pre>
<?php
ob_end_flush();
print_r(apache_request_headers());
?>
</pre>
Results in
Array
(
[Content-Location] => phpinfo.de.php
[Vary] => negotiate
[TCN] => choice
[X-Powered-By] => PHP/5.1.6
[Keep-Alive] => timeout=15, max=96
[Connection] => Keep-Alive
[Transfer-Encoding] => chunked
[Content-Type] => text/html
[Content-Language] => de
)

I can confirm athlet's experience with apache_response_headers() using PHP 5.1.6. When the resulting array is empty or only contains "X-Powered-By" instead of the full list of values, you'll need to switch off output_buffering _before_ the script has been executed, for example with the following directive in .htaccess:
php_value "output_buffering" "0"
it _doesn't_ work when you do a you ini_set('output_buffering', 0); in your script. Not sure why that is so - it is not a bug in PHP, but probably has to do with how Apache populates the request values.
