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.

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

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