What are the considerations for using NowJS with PHP for real-time updates in a chat application?

When using NowJS with PHP for real-time updates in a chat application, one consideration is to ensure that the server-side code can handle the communication between the client-side JavaScript and the PHP backend. This can be achieved by setting up a Node.js server to handle the real-time communication while using PHP for other server-side operations. 

// PHP code snippet for setting up a Node.js server with NowJS for real-time updates in a chat application

// Install NowJS using npm
// npm install now

// Create a Node.js server
var http = require('http');
var server = http.createServer().listen(8080);

// Include NowJS module
var nowjs = require('now');

// Attach NowJS to the server
var everyone = nowjs.initialize(server);

// Define NowJS functions for real-time updates
everyone.now.sendMessage = function(message) {
    // Handle the message and send it to other clients
    everyone.now.receiveMessage(message);
};
