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.

Core Concepts

Dependency Injection

The Container is central. Auto-wiring is default.

Bundles

Plugin system.

Attributes

#[Route('/api', name: 'api')] replaces YAML/Annotation configs.

Best Practices (2025)

Do:

• Use Maker Bundle: php bin/console make:controller.
• Use AssetMapper: No Webpack/Node.js required for simple assets.
• Use Messenger: For async message bus (queues).

Don't:

• Don't use YAML for Services: Use PHP attributes and autowiring.
