Description:
------------
Similar to https://bugs.php.net/bug.php?id=61679, but with non-existing file path (handled by index.php).

1) > touch index.php
2) > php -S localhost:1234 index.php
3) Execute test script in another terminal

Test script:
---------------
<?php
file_get_contents(
	'http://localhost:1234/some-path',
	null,
	stream_context_create(
		[
			'http' => [
				'method' => 'PATCH'
			]
		]
	)
);
file_get_contents(
	'http://localhost:1234/some-path',
	null,
	stream_context_create(
		[
			'http' => [
				'method' => 'XYZ_METHOD_ALSO_ALLOWED'
			]
		]
	)
);


Expected result:
----------------
Empty output both in test script and PHP server

Actual result:
--------------
Test script:
PHP Warning:  file_get_contents(http://localhost:1234/some-path): failed to open stream: HTTP request failed! HTTP/1.0 501 Not Implemented
 in %s/test.php on line 10
PHP Warning:  file_get_contents(http://localhost:1234/some-path): failed to open stream: HTTP request failed! HTTP/1.0 501 Not Implemented
 in %s/test.php on line 21

PHP server:
[%s] 127.0.0.1:%d [501]: /some-path - No such file or directory

Note that PHP server doesn't print anything for PATCH method (for whatever reason, but it is a part of issue anyway).
