Evan Coury has a new post looking at setting up environment specific configurations in a Zend Framework 2 application letting you switch between configs based on an environment variable.
So you're all excited to try out ZF2. You clone the skeleton, install some modules, maybe even follow Rob Allen's excellent ZF2 tutorial, and finally, start building your application. Now, if you're a former ZF1 user or refugee from another framework, you might be troubled at this point by the fact that, at first glance, ZF2 doesn't appear to take into consideration environment-specific configuration values (e.g., development, testing, staging, production). Luckily, this is not the case!
He includes a bit of sample code showing how you can use a simple getenv call to pull in the value from an "APPLICATION_ENV" environment variable and put it into an autoload path.
