SF4C3 | Extending & Hacking Symfony 4

  • This training leads you to the greatest Symfony 4 level and helps you improve and confirm your current knowledge of the Symfony 4 framework! The training focuses on how to easily hack and extend some parts of the Symfony framework thanks to the dependency injection container. You'll also learn how to master some advanced tools such as the form and validation components, as well as the event dispatcher system to decouple your code.

  • Prerequisites

    Mastering Symfony 4

  • Goals

    In two days only and thanks to our expert instructors, you'll be able to improve your current Symfony skills. This training helps you to better understand how Symfony works under the hood and how you can easily hack and extend the configuration layer, the HTTP kernel, the form and validator components as well as the authentication and authorization layers. Be prepared to effectively master Symfony and its internals!
