# Symfony

> Symfony is a mature, modular PHP framework built from independent, reusable components, used to create large, scalable web applications.

**Symfony** is a mature, open-source [framework](https://nodea.io/en/glossary/framework) for the [PHP](https://nodea.io/en/glossary/php) language, created by SensioLabs and first released in 2005. Its distinctive feature is a design based on independent, reusable components, which can be used together as a full framework or individually in any PHP project. Symfony is one of the pillars of the PHP ecosystem — its components form the foundation of many other tools, including parts of [Laravel](https://nodea.io/en/glossary/laravel).

## How Symfony works

Symfony organizes an application around the MVC pattern and emphasizes clean architecture and good software-engineering practices. At the framework's heart are components — standalone libraries responsible for specific tasks:

- **HttpFoundation and Routing** — handling requests, responses and URL mapping;
- **Doctrine ORM** — mapping the database to PHP objects;
- **Twig** — a secure and efficient templating engine;
- **Dependency Injection** — a container that organizes the application's structure;
- **Console** — building commands run from the command line.

Symfony's philosophy is configurability and predictability. The framework imposes fewer ready-made solutions than some competitors, giving the developer full control over the architecture, which is an advantage in large, long-maintained systems.

## Practical application

Symfony is most often chosen for building large enterprise applications, SaaS platforms, CRM and ERP systems, high-traffic portals and APIs. Popular content management systems such as Drupal are also built on its components. The framework works well where scalability, stability and long-term support matter — Symfony has a clear release policy with LTS versions.

A Symfony application is deployed on a server with PHP support, most often together with [PHP-FPM](https://nodea.io/en/glossary/php-fpm) and a [MySQL](https://nodea.io/en/glossary/mysql), MariaDB or PostgreSQL database. Full control over the PHP version, caching and queue configuration comes from a [VPS](https://nodea.io/en/glossary/vps) or a managed server, where the environment can be tuned to the project's needs. Extensive documentation, an active community and a rigorous approach to code quality keep Symfony one of the most important PHP frameworks.

### How is Symfony different from Laravel?

Symfony is a set of independent, highly configurable components — some of which Laravel itself builds on. It emphasizes flexibility and control, which suits large enterprise systems. Laravel, by contrast, ships ready-made solutions with minimal configuration and prioritizes development speed.

### What are the hosting requirements for a Symfony application?

Symfony needs a server with a currently supported PHP version and a full set of extensions, the Composer dependency manager and, most often, a MySQL, MariaDB or PostgreSQL database. For efficient work it benefits from CLI access and the ability to configure caching. A VPS or a managed server with full control over the PHP environment works best.
