Problem short (theoretical) : is it possible to send a flag from one php script to running php script that is used as websocket server to notice about database change?
Problem long (theoretical) : The current app is using websocket already - when user sends a new data (lets assume - message) in client.html it is sent to server server.php, aggregated and written back to the socket. Now the problem occurs: another users sends in data to json.php that does processing and insert|update database table. After that has been done the json.php should warn server.php about the DB change and server.php should send (socket write) to client.html.
