Clean Architecture

This example demonstrates clean architecture with separation between Domain and Infrastructure layers, using AbstractRepository and PHP 8 attributes.

What This Example Shows

• Pure domain entities (no framework dependencies)
• Table definitions using PHP 8 attributes (#[Table], #[Column])
• Repository extending AbstractRepository for data access
• Building tables with AttributeTableBuilder

Files

• example.php - Main example code
• Domain/User.php - Pure domain entity
• Infrastructure/Schema/UserTable.php - Table definition with attributes
• Infrastructure/Repository/UserRepository.php - Repository using AbstractRepository

Running the Example

php example.php

Expected Output

The example demonstrates how domain entities remain framework-agnostic while infrastructure handles database operations using attributes and AbstractRepository.
