 Summary:            fopen follows redirects for non-3xx statuses
 Status:             Closed

 New Comment:

I saw git diff, and 308 permanent redirect is missing in the code:
/* we only care about Location for 300, 301, 302, 303 and 307 */

Since 308 is Permanent Redirect in http 1.1, it should be included also to be 
followed and not ignored, otherwise, this bug might happen again on some 
servers.

A more complete example confirms this behavior:

I also fixed some syntax errors

<?php

header('Location: http://php.net', true, 201);

if (isset($_GET['waa']))
    return;

$context = stream_context_create(array(
    "http" => array(
        "method"  => "POST",
        "header"  => "Content-Length: 13",
        "content" => "{\"foo\":\"bar\"}",
    ),
));

$fp = fopen('http://'.$_SERVER['SERVER_NAME']. $_SERVER['PHP_SELF'] .'?waa=1', 
'r', null, $context);
print(stream_get_contents($fp));

Description:
------------
The HTTP location header can either be used to direct the user to another 
resource (when accompanied by a 3xx status code) or to inform the user of the 
location of the document they just created (with a 2xx) status code.

It doesn't make sense to treat the location header as a redirect in the second 
context - the location header indicates a redirect only when accompanied by a 
3xx 
status code.

Currently, PHP follows Location headers as if they are redirects regardless of 
the returned status code.

Test script:
---------------
$context = stream_context_create([
    "http" => [
        "method"  => "POST"
        "header"  => "Content-Length: 13"
        "content" => "{\"foo\":\"bar\"}",
    ],
]);

// Returns HTTP/1.1 201 Created
// Location: http://example.com/mydb/documentid
//
// {"status":"ok"}
$fp = fopen('http://example.com/mydb', 'r', null, $context);
$data = stream_get_contents($fp);

list($headers, $body) = explode("\r\n\r\n", $data, 2);
echo $body;

Expected result:
----------------
{"status":"ok"}

Actual result:
--------------
{"foo":"bar"}
