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.
Flexibility
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.
Maintainability
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!
Community
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.
Stability
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!
Performance
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!
