I've run across an interesting PHP/SOAP error that has me stymied. After searching I have not found a plausible explanation, and I'd appreciate your help. Here's the background:
I have a site built in PHP/CodeIgniter which uses SOAP to communicate over SSL with a back-end system provided by a third party (let's call them "Company X" to protect the innocent) not in my control. In the spirit of good MVC, I put the code specific to interacting with that data source in a separate model (system/application/models/company_x.php). I have been developing locally using MAMP on my Mac, and just about everything was relatively smooth through testing and development; including calling Company X's web service over SSL. I should probably mention that their web service had strange WSDL that PHP 5's SOAP didn't like. Things like required parameters that were not there. It's been a little odd to call SOAP methods very explicitly, but I got it going and it worked through testing. I even deployed it to a test site at Mosso, and I could have sworn that it worked for a time up there too.
Imagine my surprise when every call to the SOAP web service starting producing errors like the following:
A PHP Error was encountered
Severity: Warning
Message: SoapClient::__doRequest() [soapclient.--dorequest]:
WARNING: URL fopen access
Filename: models/company_x.php
Line Number: 86
The error logs didn't give any more information other than the full path to the model file on the server. It works locally, and I thought it worked on Mosso before. Maybe Mosso changed their settings, and disabled SOAP or something. A little phpinfo() later, and they have more than enough. I thought that maybe my Mac is more tolerant of the SSL certificate. After all, it's a GoDaddy *.domain.com cert, maybe fopen is having trouble getting through. I whipped up a test file to connect over SSL, and put it on Mosso and it worked.
I'm wondering why is fopen access suddenly a problem for SOAP? What is it about Mosso that is making this difficult suddenly? Do I need to override some php.ini setting? Could it be, like is so often with unhelpful errors like this, something completely different?
Update: here is the configure command from phpinfo():

Note: My comment below that phpinfo() reports that furl is allowed; weird!
