Extending Symfony2: ParamConverter

Symfony2 is an extremely extendable framework, everything is extendable or overwritable through the Dependency Injection Container. The problem developers face is knowing about the extension points and when to use them. If you don’t know the extension points, your Symfony application will end up with code duplication, too much inheritance and very little unit-testable code.

This blog post will be the first in a series, describing Symfony2 extension points that help you achieve clean and duplicateless code. In my experience, using Symfony extension points to avoid code duplication helps you avoid writing thousands of lines of code in your controllers.
