title: Using Node as REST server alongside PHP
body: <p>I've got a functional site running right now in PHP on apache; PHP and apache are serving the needs of serving the site content quite nicely.  I'm looking to convert my existing PHP API server code to a RESTful interface; most of the design issues are worked out on that front.  PHP doesn't seem like a good fit for a RESTful interface, though; enter Node.js.</p>
  
  <p>I'd like to run my REST API from a node.js server, while still serving my site content from PHP.  Is this a reasonable approach, and are there any potential troubles waiting in the wings?  I'm planning on using express to simplify the process of REST API development.</p>
