By definition, a HEAD request MUST NOT return a message-body.
This works as expected:
<?php
header("X-Request-Method: " . $_SERVER["REQUEST_METHOD"]);
?>
Here is how it works: main/SAPI.c has code that set
SG(request_info).headers_only = 1 for HEAD requests, and as a
consequence php_request_shutdown() does not flush the output buffer
(if any) to the client. You can force a body to be sent (but that's
likely not going to work with every SAPI) by not having an output
buffer or by calling ob_end_flush() yourself.
