To start with, let's define what the framework is. A framework is a platform for the development of software applications. In other words, it is a basement for web application development. Because, let's agree, if you want a beautiful kitchen in it, you first need a house to build the kitchen in.
We all know that PHP is the king of web development. Even though more and more programming languages are becoming popular nowadays, something needs to stay classic. That's about PHP development.
Symfony was created in 2005 and made it best to gain the reputation of the most reliable, stable, feature-rich PHP framework. Symfony was released in 2005 and has made a long way to win the reputation of the most mature and reliable PHP framework. If you need a trustable web application development framework — you need to turn to the Symfony.
Symfony has a significant advantage — it is commercially supported. SensioLabs, the company-creator and sponsor, actively contributes to its reputation. Every update is making the process of web development much easier. The latest, Symfony 5, was released on November 21th 2019.
— The new Symfony brings automation to the next level
Symfony 5 integrates seamlessly with Symfony Flex to automate the most common tasks performed by applications. The automation leverages the Symfony Recipes, which contain instructions to integrate hundreds of third-party bundles and packages into Symfony applications.
— Leaner, Faster, Symfony 5
The Symfony 5 source code has 37,000 fewer lines of code and runs 7% faster than the previous Symfony 4.x version.
— New Components
Symfony 5 includes a new String component that provides an object-oriented API to work with UTF-8 Strings using bytes, code points, and grapheme clusters.
— Rocking framework for the star business
The Symfony 5 framework is built with the latest version of the Symfony Components, the most popular set of libraries in PHP's history. Battle-tested in all popular PHP projects and with billions of downloads.
The framework using is not 100% necessary while developing a web application. But if you can make it better and more effective, who will not do it?
And there are a couple of reasons to integrate Symfony as soon as possible:
Symfony can adapt to every need you have while developing. Its dependency injector and the Event Dispatcher make it entirely configurable, with each of the bricks being fully independent.
While Symfony is one of the few commercially supported by SensioLabs, there is also an entire ecosystem that has grown up around Symfony since its launch and the many other service companies that have invested in the framework.
Like many other platforms, Symfony passed fire water and copper pipes. And it has proven its reliability while others failed. It's a plus to the framework if such huge players like phpBB, Drupal, Magento, and eZ Publish use its components (both for the platforms and their websites).
Symfony is there for you. It is everything you expect from a framework: speed, flexibility, reusable components, etc. This framework is always striving for better and learning from the community.
While other frameworks might not support the oldest versions, Symfony provided 3-year support for major versions. The release principle allows ensuring compatibility between all minor versions.
Suppose you already have a web application and you made a decision to migrate to Symfony. In that case, you might not even have to rewrite the whole application, but to move the functionality with the special tools. The Symfony is ready to make your web development process safe and sound. And it can be life-saving in the good hands of the talented development team.
