PHP Coding Style

This file extends the common coding style rule with PHP specific content.

Standards

• Follow PSR-12 formatting and naming conventions.
• Prefer declare(strict_types=1); in application code.
• Use scalar type hints, return types, and typed properties everywhere new code permits.

Immutability

• Prefer immutable DTOs and value objects for data crossing service boundaries.
• Use readonly properties or immutable constructors for request/response payloads where possible.
• Keep arrays for simple maps; promote business-critical structures into explicit classes.

Formatting

• Use PHP-CS-Fixer or Laravel Pint for formatting.
• Use PHPStan or Psalm for static analysis.
