Implementation Guidelines

Coding Style (PSR Standards)

  • PSR-12: Enforce 4-space indentation and opening braces on same line for functions/methods.
  • Organization: One class per file; use statements follow namespace. Run PHP CS Fixer with PSR-12 preset.
  • Naming Conventions: Use PascalCase (UserService) for classes, camelCase (getUserById) for methods/variables, and SNAKE_CASE (MAX_RETRIES) for class constants.

SOLID Principles in PHP

  • SRP: Single Responsibility Principle — extract each into its own focused class; keep classes under ~200 lines.
  • Dependency Inversion: inject via constructor with interface type-hints. Inject dependencies via constructor for testability. Favor composition over deep inheritance chains.
  • Separation of Concerns: Use Interfaces for decoupling integrations and logic.

Logic & Performance

  • Guard Clauses: Return early for error conditions (e.g., if (!$user) return null); no else after return to reduce nesting depth.
  • Traits: Define trait HasTimestamps (e.g., use HasTimestamps) for cross-cutting behavior. Keep traits focused and lightweight.
  • Helper Functions: Avoid global-namespace logic; organize in classes.

Anti-Patterns

  • No monolithic classes: Each class one responsibility (SRP).
  • No hardcoded magic numbers: Define as named class constants.
  • No deep nesting: Use guard clauses to return early.
  • No echo in services: Return data; let controller output.
