Description:
------------
The function header() and headers_list() works as expected when run from PHP 5.1.6 run from the command line however in PHP 5.2.0 when run from the command line headers_list() is an empty array.

I'm not really sure if this was a bug or intentional. In most cases it probably is not needed for command line programs. In my case my command line program is a personal web server and I use headers_list() to find any custom PHP headers to send to the browser.

If it was removed intentionally then maybe the header() function and headers_list() should be removed from the command line interface. That way it would be consistent and the few of us that need that functionality can add it back in with identical functions written in PHP code.
Thanks for your time and help!


Reproduce code:
---------------
<?php
//could be any custom header
header("Cache-Control: no-cache"); 
print_r(headers_list());
?>

Expected result:
----------------
Array
(
    [0] => X-Powered-By: PHP/5.2.0
    [1] => Cache-Control: no-cache
)

Actual result:
--------------
Array
