SymfonyLearn basics of Symfony

Symfony is a well-known enterprise PHP framework. Learning and coding Symfony with is easy. Our guide is developed to support all difficulty levels, and with live streams and videos from our community, you’ll have insights into specific projects built on Symfony PHP framework. Join Symfony coders from San Francisco, London, New York, Moscow, Beijing and Sao Paolo.


Introduction to Symfony PHP Framework (Reference)

Symfony is a PHP web application framework for MVC applications. Symfony is free software and released under the MIT license. The website launched on October 18, 2005.

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.

History of Symfony Framework (References)

The first stable Symfony version — 1.0 — was released in the beginning of 2007 and was supported for three years. In mid-2008, version 1.1 was presented, which wasn’t compatible with the previous release, and it was difficult to upgrade any old project to this.

Symfony 1.2 version was released shortly after this, at the end of 2008. Migrating between these versions was much easier, and there were no dramatic changes in the structure. The final versions of Symfony 1’s legacy family was released nearly one year later. Simultaneously, there were two version releases, 1.3 and 1.4. Both were identical, but Symfony 1.4 did not have deprecated features, and it was recommended to start new projects with it. Version 1.4 had 3 years of support.

If you look into the code, version 1.x was very different from version 2. The company that was behind Symfony (the French company, SensioLabs) made a bold move and decided to rewrite the whole framework from scratch.

The first release of Symfony2 web framework wasn’t perfect, but it was very promising. It relied on Git submodules (the composer did not exist back then). The 2.1 and 2.2 versions were closer to the one we use now, although it required a lot of effort to migrate to the upper level. Finally, the Symfony 2.3 was released — the first long-term support version within the 2.x branch. After this version, the changes provided within the next major versions (2.4, 2.5, and 2.6) are not so drastic and usually they do not break compatibility.

Symfony 2.7.0 has been released in May 2015, 2.7 is the new LTS version of Symfony.

Symfony 2.7.0 comes with more than 100 new features and enhancements.

The transition from 2.6 to 2.7 represented new ways of doing things and removing deprecated features in 3.0.

Symfony 2.8.0 has been released in October with a host of bug fixes.

Symfony 3.1.0 has been released on may 30, 2016. As always, backward compatibility means that you should be able to upgrade easily without changing anything in your code.

    A Year With Symfony: Writing healthy, reusable Symfony2 code

    byMatthias Noback

    I've written A Year With Symfony for you, a developer who will work with Symfony2 for more than a month (and probably more than a year). You may have started reading your way through the official documentation ("The Book"), the cookbook, some blogs, or an online tutorial. You know now how to create a Symfony2 application, with routing, controllers, entities or documents, Twig templates and maybe some unit tests. But after these basic steps, some concerns will raise about.

    Projects using Symfony (Reference)

    Symfony is not only a popular framework used by many small and big corporations, but it is also the best platform to build Open-Source projects. Many PHP projects are embedding some of our components or are using the full-stack framework, and we wanted to thank them on our website. Sharing is one of our core value and we like to think about those projects as being part of the Symfony "family".

    Drupal is an open source content management platform powering millions of websites and applications. It's built, used, and supported by an active and diverse community of people around the world. Drupal is open source software maintained and developed by a community of 1,000,000+ users and developers. It's distributed under the terms of the GNU General Public License (or "GPL"), which means anyone is free to download it and share it with others.
