facepalm. Php or the frontend interface only for receiving requests from users not executing them. When user makes order, the server replies, "yes we got it", and come up with a script on the backend to process user requests atomically -- trader order, deposit, withdraw... once it's done on the backend, send ajax / websocket responds back to the front end that it's done, etc, or have user refresh it manually if such lazy.
