Symfony is a complete framework designed to optimize the development of web applications by way of several key features. For starters, it separates a w eb application’s business rules, server logic, and presentation views. It contains numerous tools and classes aimed at shortening the development time of a complex web application. Additionally, it automates common tasks so th at the developer can focus entirely on the specifics of an application. The end result of these advantages means there is no need to reinvent the w heel every time a new web application is built!
