Bug #76039 [NEW]: header() not sending headers on empty output
From: yunosh
Operating system: Linux
PHP version: 7.0.28
Package: Apache2 related
Bug Type: Bug
Bug description:header() not sending headers on empty output
Description:
------------
Not sure if other SAPIs are affected too, but at least I could not
reproduce this with PHP's builtin server.
If sending HTTP headers with the header() method, these headers are no
longer sent if the HTTP response body is empty. This can be worked
around by flush()ing manually.
PHP 7.0.25
Test script:
---------------
header('X-Foo: bar');
// flush();
// echo "foo";
exit;
Expected result:
----------------
HTTP/1.1 200 OK
Date: Thu, 01 Mar 2018 15:24:28 GMT
Server: Apache/2.4.18 (Ubuntu)
X-Foo: bar
Vary: Accept-Encoding
X-Mod-Pagespeed: 1.13.35.2-0
Cache-Control: max-age=0, no-cache
Transfer-Encoding: chunked
Content-Type: text/html; charset=UTF-8
Actual result:
--------------
HTTP/1.1 200 OK
Date: Thu, 01 Mar 2018 15:24:12 GMT
Server: Apache/2.4.18 (Ubuntu)
Cache-Control: max-age=0, no-cache
Content-Length: 0
Content-Type: text/html; charset=UTF-8
