WebRTC Signaling in PHP (Codeigniter) application

I have a working Codeigniter application and I want to add live Video chat over WebRTC. The video chat will only be accessible to authenticated users (this part will not be covered in this project). I need code for the signaling (managing) process involved when working with RTCPeerConnection. The application runs on a MySQL database. I don't need the code to be written for Codeigniter (I can do this myself), just PHP. The code needs to handle just 2 peers at a time. The winner will only be paid after I test the code and it's fully working. I will answer any questions over a PM.
