I Keep getting HTTP 500. How do I effectively debug my app?

I was intrigued by your problems and cut and paste your code into a controller. The Browser displayed this screen:

I run Win7, Php 5.35 and Wamp 2.0.

I played about with the error_reporting and display errors and the same message appeared.

Code:

error_reporting(-1);
  ini_set('display_errors', TRUE);
