In this course, we’re going to kick off your Symfony journey by building an events application. To sweeten the deal, you’ll also be mastering the most important concepts used across all frameworks and web apps in general, because Symfony builds on the shoulders of other giants. Through building with Symfony, you’ll also be learning general programming best practices. Through these tutorials, you will start a new project using Symfony 2, and explore the core areas, like routing, controllers, requests, responses and templating, along with a few additional tools like Doctrine. This first lesson gives a quick overview of what Symfony is and why you would use it.
