The ServerGrove blog has a new post today in their Symfony2 component spotlight series, this time focusing on the Config component.

After a few weeks, we continue with the Symfony2 components series. This time we are going to be talking about the Config component, which helps you to load and validate configuration values, regardless of their source.

They show how it can be used to parse YAML files and give a basic overview of its architecture. Sample code is included for a "blog generator" example that parses the given YAML structure and a loader to pull in the file. The component also includes caching functionality for larger configurations and allows you to define multiple loaders for different sources.
