symfony 1 vs. Symfony 2

Same philosophy

Rewritten from scratch



symfony 1 != Symfony2


If you used symfony 1.x

better forget about it.



Symfony 2

“First, Symfony2 is a reusable set of standalone, decoupled, and cohesive PHP components that solve common web

development problems.Then, based on these components, Symfony2 is also a

full-stack web framework.”

a directory structure, a default configuration.
