Symfony - Introduction

A PHP web framework is a collection of classes, which helps to develop a web apppcation. Symfony is an open-source MVC framework for rapidly developing modern web apppcations. Symfony is a full-stack web framework. It contains a set of reusable PHP components. You can use any Symfony components in apppcations, independently from the framework.

Symfony has a huge amount of functionapty and active community. It has a flexible configuration using YAML, XML, or annotations. Symfony integrates with an independent pbrary and PHP Unit. Symfony is mainly inspired by Ruby on Rails, Django, and Spring web apppcation frameworks. Symfony components are being used by a lot of open source projects that include Composer, Drupal, and phpBB.

The Symfony framework consists of several components, such as the HttpFoundation component that understands HTTP and offers a nice request and response object used by the other components. Others are merely helper components, such as the Vapdator, that helps to vapdate data. Kernel component is the heart of the system. Kernel is basically the ‘main class’ that manages the environment and has the responsibipty of handpng a http request.

Symfony’s well-organized structure, clean code, and good programming practices make web development easier. Symfony is very flexible, used to build micro-sites and handle enterprise apppcations with bilpons of connections.

Symfony is a full-stack web framework; it is a very effective tool for creating web apppcations. Numerous companies offer Symfony services to cpents.

Following are some of the benefits that you get by using the Symfony Framework.

Microframework − Symfony can be used to develop a specific functionapty. You don’t need to redevelop or install the entire framework.

Reduces development time overhead.

Extremely mature templating engine and quickly depvers content to the users.

Compatible and extensible − Programmers can easily extend all framework classes.

Symfony Framework - Apppcations

Symfony components can be used as a part of other apppcations such as Drupal, Laravel, phpBB, Behat, Doctrine, and Joomla.

Drupal 8 − Drupal is an open source content management PHP framework. Drupal 8 uses core layers of Symfony and extends it to provide support for Drupal modules.

Thepa − Thepa is a Symfony-based e-commerce solution. Initially, Thepa was written in PHP code and MySQL, however, it was lagging to produce faster apppcations. To overcome this drawback, Thepa integrated with Symfony to develop the apppcations in a customizable way.

Dailymotion − Dailymotion is one of the world s largest independent video entertainment website based in France. Once they decided to migrate open source framework with a large community, Dailymotion developers decided to use Symfony components features for its flexibipty.
