Slim 3 was released 3 months ago and it was significant. It is one of the first frameworks to integrate the latest standards and concepts in its core.
[...] While PSR-7 and middlewares are very interesting, what's more useful for us is the use of container-interop. That means Slim 3 can work with any dependency injection container. It is very easy to replace the default container (Pimple) with PHP-DI, but today we are releasing a "PHP-DI - Slim" bridge that goes a little further.
They then show how to use their new bridge to create controllers as services in the container and pass them parameters. The post ends with the instructions on getting the PHP-DI bridge installed and how to use it to replace the default
AppSlim creation of your application.
