Fabien Potencier @fabpotParis, France Sensio CEO (sensiolabs.com) and Symfony lead developer (symfony.com)http://fabien.potencier.org WorkCEO at Sensio AboutFabien discovered the Web in 1994, at a time when connecting to the Internet was still associated with the harmful strident sounds of a modem. Being a developer by passion, he immediately started to build websites with Perl. But with the release of PHP 5, he decided to switch focus to PHP, and created the symfony framework project in 2004 to help his company leverage the power of PHP for its customers. Fabien is a serial-entrepreneur, and among other companies, he created Sensio, a services and consulting company specialized in web technologies and Internet marketing, in 1998. Fabien is also the creator of several other Open-Source projects, a writer, a blogger, a speaker at internatio 9. Fabien Potencier

Publica ainda na rede social dos codificadores vrios repositrios pblicos de projetos 18. https://github.com/fabpot 19. Oficializao do Symfony2... After 12 preview releases, 5 beta versions, and 6 release candidates, I'm very orgulhoso to announce the immediate availability of Symfony 2.0, final version. Since the first preview release, published 18 months ago during the Symfony Live conference, the Symfony community has done an amazing work. The Symfony2 code quality would not have been the same without their outstanding work. Thank you! Symfony 2.0 (http://symfony.com/blog/symfony-2-0)by Fabien Potencier July 28, 2011 20. A comunidade...

  • The involvement of the community for this version of the framework is just incredible. More than 250 developers have contributed in one way or another to this major version through more than 2,000 pull requests

21. Since March 2011, more than 100 new contributors have joined the Symfony2 team (250 vs 150); and more than 250 new bundles have been created on Github (440 vs 170) Symfony 2.0 (http://symfony.com/blog/symfony-2-0)by Fabien Potencier July 28, 2011 22. What is Symfony2?

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

23. Then, based on these components, Symfony2 is also a full-stack web framework 24. Dependendo do seu projeto e de suas necessidades, voc pode escolher alguns dos componentes do Symfony2 e iniciar o projeto com eles, ou voc pode usar tudo do framework e se beneficiar com a integrao que ele proporciona Fabien Potencier publicado em seu blog pessoal (25/10/11) 25. Is Symfony2 an MVC framework?

  • If you look around, every single framework seems to implement the MVC pattern. And most of them are advertised as MVC frameworks... but not Symfony2
    • Porque eu realmente no me importo se o Symfony2 ou NO MVC;
  • And if you like to call Symfony2 an MVC framework, then you should know that Symfony2 is really about providing the tools for the Controller part, the View part, but not the Model part
    • Para voc criar seu modelo faa no brao ou ento use alguma ferramenta ORM, como por exemplo, o Doctrine.
  • I don't like MVC becausethat's not how the web works . Symfony2 is an HTTP framework; it is a Request/Response framework. [...] The fundamental principles of Symfony2 are centered around the HTTP specification

Fabien Potencier publicado em seu blog pessoal (25/10/11) 26. Is Symfony2 an MVC framework?

  • One of the Symfony2 goals is to provide building blocks for other projects. But what do I mean when I say projects? Who are the target users for Symfony2?Everybody : from personal projects to commercial ones; and Open-Source ones

27. Symfony2 is a great framework for bigger projects where tens of developers are involved and where the business logic is more complex. And the Symfony2 components are for people who don't want to use a framework, or for other Open-Source projects thatdon't want to reinvent the wheel Fabien Potencier publicado em seu blog pessoal (25/10/11) 28.

  • Dependency Injection : pattern extensively and it comes with a built-in Dependency Injection Container. It makes Symfony2 very flexible and easily customizable

49. Distributions : A distribution is a pre-configured Symfony2 project with a selection of bundles and sensible defaults. The Symfony Standard Edition also comes with a Web configurator. That makes the installation and configuration of a new Symfony2 project fast and insanely easy 50. Everything is a Bundle in Symfony2 : A bundle is a directory containing a set of files (PHP files, stylesheets, JavaScripts, images, ...) that implement a single feature (a blog, a forum, etc). That changes everything. Share your bundles between your projects or publish them in the wild 51. Symfony2 is Fast : the raw performance of the framework is great, but there is more 52.

  • First:documentation
    • As you all know, code is not everything. Symfony2 also comes with great documentation. The documentation is made of a " Quick Tour " tutorial, aBook , aCookbook ; but also anindex , a http://symfony.com/doc/current/glossary.html glossary , and areferencesection. And for hardcore documentation, you can have a look at the beautifulAPIdocumentation.
