Symfony2 Standard Edition welcome page
|Initial release||October 22, 2005|
|Stable release||2.3.7 / November 14, 2013|
|Type||Web application framework|
Symfony should not be confused with Symphony CMS.
Symfony aims to speed up the creation and maintenance of web applications and to replace repetitive coding tasks.
Symfony has a low performance overhead used with a bytecode cache.
Symfony is aimed at building robust applications in an enterprise context, and aims to give developers full control over the configuration: from the directory structure to the foreign libraries, almost everything can be customized. To match enterprise development guidelines, Symfony is bundled with additional tools to help developers test, debug and document projects.
Symfony makes heavy use of existing PHP open-source projects as part of the framework, including:
- Propel or Doctrine as Object Relational Mapping layers
- PDO Database abstraction layer (1.1, with Doctrine and Propel 1.3)
- PHPUnit, a unit testing framework
- Twig, a templating engine
- Swift Mailer, an e-mail library
Symfony also makes use of its own components, which are freely available on the Symfony Components site for various other projects:
- Symfony YAML, a YAML parser based upon Spyc
- Symfony Event Dispatcher
- Symfony Dependency Injector, a Dependency Injector
- Symfony Templating, a templating engine
- script.aculo.us, for visual effects
- lessphp, a LESS to CSS converter
- TinyMCE or CKEditor, for Rich Text Editing
- TCPDF, a PHP library for generating PDF documents
Symfony is sponsored by SensioLabs, a French software developer and professional services provider. The first name was Sensio Framework, and all classes were prefixed with sf. Later on when it was decided to launch it as open source framework, the brainstorming resulted in the name symfony (being renamed to Symfony from version 2 and on), the name which depicts[clarification needed] the theme and class name prefixes.
Symfony is used by the open-source Q&A service Askeet and many more applications, including Delicious and the 20 million users of Yahoo! Bookmarks. As of February 2009, Dailymotion.com has ported part of its code to use Symfony, and is continuing the transition. Symfony2 is used by OpenSky, a social shopping platform, and the Symfony framework is also used by the massively multiplayer online browser game eRepublik, and by the content management framework eZ Publish in version 5. Drupal 8 also has incorporated components of Symfony in its next release.
|Red||Release no longer supported|
|Green||Release still supported|
Symfony manages its releases through a time-based model; a new Symfony release comes out every six months: one in May and one in November.
This release process has been adopted as of Symfony 2.2, and all the "rules" explained in this document must be strictly followed as of Symfony 2.4.
