Symfony2 revealed
The document provides a history and overview of the Symfony framework. It describes the initial release of Symfony 1.0 in 2007 and key updates through 1.4 in 2009. It then introduces Symfony 2 as a next generation version with a new low-level architecture built for PHP 5.3. The document provides examples of how configuration, routing, and controllers work in Symfony 2 through PHP code snippets and configuration files. It highlights improvements in Symfony 2 like increased flexibility in configuration through the dependency injection container.

Symfony2 revealed
- 1.
- 2. A bit ofhistory
- 3. symfony 1.0 –January 2007 • Started as a glue between existing Open-Source libraries: – Mojavi (heavily modified), Propel, Prado i18n, … • Borrowed concepts from other languages and frameworks: – Routing, CLI, functional tests, YAML, Rails helpers… • Added new concepts to the mix – Web Debug Toolbar, admin generator, configuration cascade, …
- 4. symfony 1.2 –November 2008 • Based on decoupled but cohesive components – Forms, Routing, Cache, YAML, ORMs, … • Controller still based on Mojavi – View, Filter Chain, …
- 5. symfony 1.4 –November 2009 • Added some polish on existing features • Removed the support for deprecated features • Current LTS release, maintained until late 2012
- 6. Symfony Components YAML Dependency Injection Container Event Dispatcher Templating Routing Console Output Escaper Request Handler …
- 7.
- 8. Symfony 2 isthe next version of the symfony framework… except Symfony now takes a S instead of a s
- 9. Talk about Symfony 2 or symfony 1
- 10. To make itclear: Symfony 1 does not make any sense
- 11. symfony 2 does notmake more sense
- 12.
- 13. Same philosophy, just better
- 14.
- 15. hmmm, now that Ithink about it…
- 16. …it’s now probablymore a Fabien’s style framework than anything else
- 17. Highly configurable Highly extensible Same Symfony Components Same great developer tools Full-featured
- 18. Ok, but whya major version then?
- 19. Symfony 2 has a brand new low-level architecture
- 20.
- 21.
