From http://php.net/manual/en/function.fsockopen.php#115405:

It appears that in PHP 5.6.0 (at least the version in Debian jessie, with openssl 1.0.1h-3), this function *is* now validating SSL certificates (in a variety of ways). First, it appears to fail for untrusted certificates (i.e. no matching CA trusted locally), and secondly, it appears to fail for mismatched hostnames in the request and certificate.

Assuming alBert2000 is testing with a 5.6+ PHP, it sounds like we might add "tests for expired certificates" to this list.
