We recently had a very strange php SOAP issue that cropped up right after an upgrade to PHP on a development server took place. It was a basic SOAP call to Fedex webservices that had always worked before.

It was strange, since we could easily CURL a response to the same Fedex HTTPS url without any issue.

//'trace' => 1,
'stream_context' => stream_context_create(array(
'ssl' => array(
'verify_peer' => false,
'verify_peer_name' => false,
'allow_self_signed' => true //can fiddle with this one.
)
))
));
