PHP 8 Patterns for Modern Applications
Practical PHP 8+ patterns for cleaner architecture, safer input handling, and maintainable backends.
PHP 8+ is an excellent foundation for robust web backends when used with discipline.
Prefer strict typing
Enable declare(strict_types=1); and use typed properties, return types, and enums where they clarify intent.
Keep boundaries clean
Separate request validation, domain logic, and presentation. Thin controllers. Explicit services. Predictable data flow.
Security by default
Sanitize early, escape late, verify CSRF tokens, rate-limit sensitive endpoints, and never trust client input.
Ship with observability
Structured logs, meaningful errors, and health checks turn production surprises into manageable events.
