Answer 1

If you're using the ws library for node you can get the URL from the second argument to ws.connection which is the request object:

const server = new http.createServer()
const wss = new WebSocket.Server({ server })

wss.on('connection', (ws, req) => {
  console.log(req.url)
})

Answer 2

There isn't a native way to work with websockets in PHP or Node. You'll need to use a library of some sort. Fortunately, there are plenty to choose from:

Node.JS

PHP
