 Symfony app development

What is Symfony?

Symfony is a web application development open-source PHP framework and a set of reusable PHP components. It was firstly introduced in 2011 by Fabien Potencier and is backed by SensioLabs. This framework is responsible for the whole backend of a web application. Building an application means that it will be delivered fast and with excellent quality because of the built-in Symfony components such as form management, limiting tedious activities during development. It also leads to a more accessible work environment for developers and your future self! Symfony is most often used for large projects. However, we also have smaller projects made using it.

Why Symfony?

Symfony is used for many reasons, but mainly because of its benefits. Please take a look at them!

Rapid and quality development

Rapid and quality development

Symfony's components make creating web applications really fast! Instead of tediously rewriting lines of code, the PHP developer can use Symfony libraries, which allow to implement elements and focus on the essential things quickly. Such a solution lowers the development cost too! Many other competing Frameworks, such as Laravel , are based on Symfony components which only shows how valuable those are.



Symfony is built in a modular way, which means that it integrates easily with extensions (bundles) and has its PHP code libraries. Such a large number of additional modules allows you to create both large web applications for enterprises and smaller ones for SMEs / startups because there will always be a solution. Moreover, your application can be easily edited because it will be created on independent elements. That's what is called flexibility! With Symfony, you can build a whole complex system, make your framework or replace only a given element in an existing project.



The Symfony structure: Model View Controller allows for much better maintenance after the end of web development. It is because MVC divides the application into a business structure and a visible structure. Changes in given systems will not interfere with each other. Moreover, it is easier for developers to cooperate thanks to such architecture because everything is nicely broken up. Updating an application written in Symfony is a pleasure!



According to the official Symfony website, the Symfony PHP framework is already used by 600k developers. Symfony trumps any other PHP frameworks communities! Thanks to such a large technological community, it is constantly developing, and you can be sure that it will be supported for many years to come. Creating web applications using Symfony will always be successful from the technical point of view because we are great PHP experts. We are also supported by a multitude of materials provided every day by Symfony users.



Symfony is the perfect choice for your long-term needs, that's because it was developed by SensioLabs and is still backed by it. Thanks to that fact, Symfony comes in with guaranteed 3-year support for all the major versions, while security-related issues are supported for life! Taking all this into account, you can be sure that once created, Symfony web solutions will stay with you for a long time!



Nowadays, speed is crucial to keep the user with you. The bounce rate jumps by up to 30% with each subsequent second of loading! Fortunately, Symfony is considered to be one of the fastest PHP frameworks on the market. If you want the user to be satisfied with the performance of your application, Symfony is a good choice!

Frequently asked questions

Symfony is a PHP framework based on components. It utilizes the model-view-controller (MVC) pattern. Let's start with Symfony's heart - PHP; it is an open-source backend programming language used to write web pages and accounts for up to 80% of websites in the world! Frameworks offer many preprogrammed modules that make development faster. Developers no longer have to code each line themselves or search through libraries such as jQuery separately but can implement them right away into their projects without delay. Symfony business logic pattern - MVC. It divides the application into three separate sections: M (model) for data, V (view) as an interface to view and modify this information, and C (controller), which are operations that can be performed on our web applications. This structure ensures less clutter in your code, so you have more stability with high-performance levels. The components in the Symfony framework are nothing more than free and reusable PHP code libraries that cut down the routine coding tasks. Interestingly many PHP solutions are built on Symfony components.

As said before, SensioLabs developed Symfony, and, firstly, the initial release was in the year 2007. The name "Symfony" was created during brainstorming when the company decided to launch the open-source framework and needed to change its name from Sensio Framework.

Before version 5.0, developers could use both the Twig templating engine and PHP for templating. With the arrival of Symfony 5.0, PHP templating is no longer supported, and Twig has become the main engine. PHP templating was replaced with Twig because developers can write more readable templates and friendly web designers. These templates also offer many advantages over PHP templating languages because they're easier for developers to use and work with during the design process. Moreover, according to Symfony's official page, Twig is "{...}in several ways, more powerful than PHP templates."

It is an excellent question, and the answer to it is straightforward - tests. When writing the lines of code, we consider that there may be an error somewhere, so we carry out both unit testing and functional testing. That way, we are always sure that everything works at full throttle.

There are many PHP frameworks on the market, but the Symfony framework is one of the most popular. Symfony has many features that translate into its business benefits and more accessible work for developers (for example, PHP components that improve workflow and reduce repetitive code). The popularity of this framework is evidenced by the fact that a lot of books have been published about it. One of the oldest is "Symfony 1.3 Web Application Development" by Tim Bowler and Wojciech Bancer.

Symfony is used across many different web app projects, but the biggest ones include Spotify, Blablacar, Trivago, or Dailymotion. The world is full of Symfony-based Web Applications, and it is estimated that over 36k companies use this framework all across the globe.
