Symfony 6.4 Back-End – Web Development

Master Symfony 6.4 to build secure web apps, REST APIs, and data-driven back-end systems

Building a robust web application requires much more than just knowing PHP. Symfony imposes a structure, conventions, and a rich ecosystem—which can be intimidating at first, but become powerful allies once you master them. This training covers the entire application development process with Symfony 6.4: routing, forms, databases, security, APIs, testing, and deployment. A comprehensive path, from a blank project to production.
