Symfony

Symfony v7.1 (2025) is the bedrock of modern PHP (Drupal, Laravel components). It emphasizes Attributes (Annotations) and strict typing.

When to Use

• Enterprise PHP: Complex business logic, long-term stability (LTS).
• Components: Using standalone libraries (Console, HttpFoundation) in other apps.
• DDD: Well-suited for complex domain modeling.
