Symfony is a web framework written in PHP and a set of reusable PHP components / libraries. Symfony was released on October 18, 2005 under the MIT license.

History and philosophy

Symfony has been developed since 2005 under the leadership of Fabien Potencier . It was created parallel to the increasing popularity of Ruby on Rails and the desire for a similar MVC framework based on PHP. Symfony tries to keep the configuration to a minimum. If no configuration is specified for this, the assignment of e.g. B. Models for database tables using the same names in singular and plural ( convention before configuration ). The console application enables simple websites to be developed using rapid application development .

Version 2 was released in July 2011. It is a new implementation that is completely different from version 1. There is no easy way to migrate applications from version 1 to version 2. The framework now consists of modules, so-called bundles , which can run completely independently of one another, but can be seamlessly integrated into the framework process. By using a dependency injection container, the entire application has a modular structure. This makes it easy to test and expand. In addition, namespaces supported. So Symfony 2 requires PHP 5.3 or higher.

Bundles

Bundles are separate units of a web application. A fictitious guest book bundle therefore contains all the data required for the guest book to run completely. This includes not only the required application logic , but also database queries and resources (graphics, scripts, etc.). Developers can publish developed bundles so that other Symfony 2 users can integrate these application units without direct code changes.

layers

The Model-View-Controller design pattern is implemented by Symfony as follows:

model

There are two plugins to choose from ( Doctrine and Propel ) to save the objects . These are libraries for object-relational mapping that store PHP objects in a relational database .

The relationships between different models are determined by so-called associations .

From version 1.1 of Symfony, the previous standard framework Propel has been outsourced to a plug-in and is no longer an integral part of the framework.

View

A view is understood to be the presentation layer of the application. In the view layer, with the help of the controller, content is provided that often includes templates for the output. Any PHP code can be embedded in a template. Symfony brings so-called helpers , which can create or format certain outputs in templates, such as links or forms. For recurring expenses can be seen on partials resort which within the templates iterated are.

Controller

The controller formulates the business logic and provides interfaces in the form of methods that interact with the logic. As in many other frameworks, these interfaces / methods are also called actions . Parameters for the methods can also be passed. The structure of the URLs can be flexibly adapted with the help of routes.
