Implementing node.js and socket.io alongside my PHP website

Question

I've been learning node.js and socket.io, but I can't see how to use it without transferring everything over to node, which I'm not keen on doing. So my question is, is it at all possible to use node.js alongside PHP?

For example, say I wanted 99.9% of my site to be done in PHP, but I want to use node to display the current number of users online at the top of the page. Is this at all possible, how would I do it?

print the Socket.io code(javascript) to the page and it must connect to node.js, then starting sending data to keep a track of who is online.. but this would open like 1000connections if 1000 users are online.. if you want only that feature, try caching on php side and some ajax requests — Gntem

See that's what I'm not really understanding here. The only way I know how to connect to node is on an entirely different page (with a different port). I don't understand how to combine it with say my index.php page which connects to apache on port 80. I have to go to a specific url with the port number to view anything I've done in node. — Ian

socket.io is not related with apache, on php side you just print javascript with which you open a websocket on node.js which in turn listens on a different port — Gntem

Oh, thank you. All the tutorials I've come across have been displaying content on the node server which has made learning how to use it for practical applications problematic for me. This helps a lot. — Ian

I had a similar task for certain extent. Running multiple Node applications with other stuff, no matter static, PHP, Python or something else, on one domain. I consider the best approach is to use Nginx as a web server with appropriate configuration. Here are some details and my configuration example: http://skovalyov.blogspot.com/2012/07/deploy-multiple-node-applications-on.html
