Symfony is the leading PHP framework for building websites and web applications. The Symfony community is made up of 600,000 developers located in more than 120 countries, committed to helping all colleagues overcome every challenge.
Symfony's philosophy is to embrace and promote professionalism, best practices, standardization, and application interoperability.
If you are a beginner, the best option for you will be Laravel, for these reasons:
“Both PHP Laravel and Symfony PHP are built on the MVC architecture, but in terms of component reuse and code modularity, Symfony has an advantage over Laravel in this regard. It structures the program in an organized way and becomes the perfect fit for larger and more complex projects”, they explained on the Reach Studios portal.
