Symfony provides a structured architecture based on MVC (Model-View-Controller) principles.

Includes reusable components for routing, forms, security, templating, caching, and more.

Supports rapid development with built-in development tools, debug utilities, and profiler.

Highly extensible via bundles, plugins, and third-party integrations.

Widely used in enterprise-grade PHP applications and open-source projects.
