I am facing a problem here which I could not find a good solution for it. I am developing a mobile web app using php and I need a rule based inference engine (open source) - expert system. The only one I could find was Pyke in Python. So I need to integrate Pykes' source code with my php implementation. My service provider is not allowing any commands such as exec for security reasons. I tried PiP (Python to PHP module) but it has a lot of bugs.
I'm not familiar with Pyke; but when this type of situation arises for me, I usually end up wrapping the Python code with a web-service.  I then use PHP to make SOAP or cURL calls to the webservice.
