Loïc Faugeron has posted another in his "ultimate guide" series of posts around components in the Symfony framework. In this latest post he gives an example of using the command line component with the Console component.

In this guide we've explored the main standalone libraries (also known as "Components") provided by Symfony to help us build applications: HTTP Kernel and HTTP Foundation, Event Dispatcher, Routing and YAML, Dependency Injection and Console. We've also seen how HttpKernel enabled reusable code with Bundles, and the different ways to organize our application tree directory.

Finally we've started to put all this knowledge in practice by creating a "fortune" project with: an endpoint that allows us to submit new fortunes, a page that lists all fortunes. In this article, we're going to continue the "fortune" project by creating a command that prints the last fortune.

He walks through the use of an example repository as a base and shows:

• the creation of the command class
• the matching tests to ensure it's working correctly
• building out the logic to pull in the latest fortunes

They enter the fortunes via the web interface and use the command line to output them as as simple text.
