Symfony is a PHP framework developed by SensioLabs. Symfony 4 was released in November 2017.

Symfony is a PHP web framework first released in July 2011 and was created by SensioLabs. Symfony 4 was released in November 2017. The latest LTS is 4.4.8 released in November 2019 and has support until 2022.

Differences from Symfony 3

  • Symfony Flex automates many of the tasks that previously had to be done manually - it’s based on Symfony Recipes, which are a set of automated instructions.
  • Version 4 also recommends a bundle-less setup, e.g. putting many of the source files directly in /src instead of something like /src/AppBundle.
  • Installing using the Symfony skeleton will create a relative small version of the app. Additional packages need to be added. A more fully-featured version (more similar to the »Symfony Standard Edition« in Symfony 3) is available with the Symfony Demo Application.
  • Minimum PHP 7.1.3

Documentation / Resources

  • Overview: Documentation for current version.
  • Flex: New way to manage Symfony apps.
  • Best Practices: Best practices for developing web apps, esp. the ones using the full-stack Symfony framework.
  • Symfony Recipes Server: Includes official and community recipes.
