title: Integrate Node.js with Symfony2 or PHP
body: <p>I'm developing a web application with Symfony2. I need to create a push notifications sysmte (like Facebook). When an user publish something, I need some of another users receive a notification.</p>
  
  <p>I saw that Node.js it's the easiest manner to do this. But, I did some simple examples and all works fine, but I don't know how can I integrate this node.js application with my Symfony2 application, or really with a PHP application.</p>
  
  <p>Anybody can help me?</p>
  
  <p>Thanks in advance!</p>
