Setting up a Push server on existing PHP code
Hi,
I'm new to the Ratchet framework and facing some issue understanding how the architecture is designed. I have set up a basic Ratchet server and webSocket connection is being established from an Android client. Now, I have another PHP server that takes care of existing functionalities. I want to integrate both of these. So, the code base can be same or I would have to setup the Ratchet codebase as a separate application. 
Another issue is that how would I setup push messages from existing server. Would I have to run another PHP script on the Ratchet server or this would be sufficient?

Sorry if these questions sound naive, but pls help me..
Thanks,
