PUN+ PHP API

I'm not able to find anything on this, but our players are able to join other players via our website at worldtobuild.com. We'd like to be able to get information from photon about rooms and lobbies from our php server. Are there any solutions that make this possible? We've thought of having an instance of Unity run on the server simply to grab the information and relay it to our server, but that seems a bit complex for just retrieving a bit of information. Are their any web API available for PUN+?
