Description:
------------
Pretty simple; I'm trying to create a stream context which will send custom headers along with a simple HTTP GET request. It wasn't working so I created a second debug script to see what was up and found that PHP simply isn't including any of my custom headers. 

This *is not* a duplicate of bug #41051, I have tried that as well.

Reproduce code:
---------------
<?php
//send.php
$params = array('http' => array('method' => 'GET','header' => "Custom: woot"));
     $ctx = stream_context_create($params);
     $fp = fopen('http://localhost/recv.php', 'r', false, $ctx);
     print_r(stream_context_get_options($ctx));
     print_r(stream_get_meta_data($fp));
     echo stream_get_contents($fp);
?>

<?php
//recv.php
print_r(apache_request_headers());
?>

Expected result:
----------------
Array
(
    [http] => Array
        (
            [method] => GET
            [header] => Custom: woot
        )

)

    [wrapper_data] => Array
        (

                )

            [readbuf] => Resource id #4
        )

    [wrapper_type] => cURL
    [stream_type] => cURL
    [mode] => r
    [unread_bytes] => 0
    [seekable] => 
    [uri] => http://localhost/404.php
    [timed_out] => 
    [blocked] => 1
    [eof] =>

Array
