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? Any help is appreciated, thank you.
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
