Implementation Guidelines

• PSR-12: Follow PSR-12 for coding style (indent, braces, space).
• Autoloading: Use PSR-4 via Composer.
• Namespacing: Map namespaces to directory structure.
• PascalCase: Use for all class names.
• camelCase: Use for methods and variables.
• SNAKE_CASE: Use for class constants.
• DRY Logic: Extract repetitive logic into traits/methods.
• SOLID: Use interfaces for decoupling and SRP adherence.

Anti-Patterns

• God Classes: No Monoliths: Avoid classes with multiple responsibilities.
• Magic Numbers: No Hardcoding: Use class constants for config values.
• Deep Nesting: No Nesting: Guard clauses over nested if/else.
• Direct Output: No Echo: Return data; let controller handle response.
