Description:
------------
Downloading any content over HTTPS with the build-in stream-mechanism does not work as expected with some servers (e.g. Apache 2.4 mod_itk mod_ssl).
The process always blocks until the connection timeout occurs. The return value is correct, however, it takes a long time.

Fetching the same URL with Curl or by bare HTTP works fine.
It affects all versions of PHP.


Test script:
---------------
<?php

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.ec-elements.com/sitemap.xml');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$t1 = microtime(true);
$output1 = curl_exec($ch);
$t2 = microtime(true);
echo "curl_exec: ".($t2-$t1)." s\n";

$t1 = microtime(true);
$output2 = file_get_contents('https://www.ec-elements.com/sitemap.xml');
$t2 = microtime(true);
echo "file_get_contents: ".($t2-$t1)." s\n";


Actual result:
--------------
curl_exec: 0.11854910850525 s
file_get_contents: 60.250888824463 s

I can reproduce this as well.

Daniel, this feels like something you probably know about. Can you have a look, please?

I haven't had a chance to look at this yet -- have been *really* busy. It may be related to the problems surrounding the attempted fix for https://bugs.php.net/bug.php?id=41631 that has been haunting me, although those changes were supposed to be held out from the 5.6 branch.

Anyway, will try to find time ASAP to work it out. Thanks for the report.

We ran into this also. But we were working just fine for about a month (Few days short of 30 days). We average about 100K hits per day and resulting in 200-300 transactions per day. Without warning, the usage of file_get_contents just died. Our work around was to go to curl, thanks for that part. We had to revert back to 5.4 (from 5.6.4) which the version we have is not PCI compliant, so I am anxious for a fix for this. We use PHP on our Windows servers. Thank you.

The original offending code was reverted for 5.6.3 (so the issue was "fixed" at that time). New updates have been pushed upstream to resolve the original bug the problematic code attempted to fix:

Please post a new report if similar behavior is observed going forward.
