SSL error SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

Question

After upgrading to PHP 5.6 I get an error when trying to connect to a server via fsockopen()..

The certificate on the server (host) is self-signed

Answer 1

Have you tried using the stream_context_set_option() method ?

$context = stream_context_create();
$result = stream_context_set_option($context, 'ssl', 'local_cert', '/etc/ssl/certs/cacert.pem');
$fp = fsockopen($host, $port, $errno, $errstr, 20, $context);

In addition, try file_get_contents() for the pem file, to make sure you have permissions to access it, and make sure the host name matches the certificate.
