Alas, the rapid prototyping is a trap I fall into all the time. Spinning up an ol' Symfony 1.4 application to mock-up a REST API so I have something to build a Backbone.js app against is the practice that keeps leaving me tethered to PHP.
If there were something that would allow me to spin up local application and work with my existing, already running Apache processes, I could move away from PHP.
Then I just invoke it with "shotgun rest.rb" and hit http://localhost:9393/ and I'm up and running. It's not running through Apache, but it's not really significantly more difficult than PHP prototyping.
