php-pro Checked

Use when building PHP applications with modern PHP 8.3+ features, Laravel, or Symfony frameworks. Invokes strict typing, PHPStan level 9, async patterns with Swoole, and PSR standards. Creates controllers, configures middleware, generates migrations, writes PHPUnit/Pest tests, defines typed DTOs and value objects, sets up dependency injection, and scaffolds REST/GraphQL APIs. Use when working with Eloquent, Doctrine, Composer, Psalm, ReactPHP, or any PHP API development.

Core Workflow

1. **Analyze architecture** — Review framework, PHP version, dependencies, and patterns

2. **Design models** — Create typed domain models, value objects, DTOs

3. **Implement** — Write strict-typed code with PSR compliance, DI, repositories

4. **Secure** — Add validation, authentication, XSS/SQL injection protection

5. **Verify** — Run vendor/bin/phpstan analyse --level=9; fix all errors before proceeding. Run vendor/bin/phpunit or vendor/bin/pest; enforce 80%+ coverage. Only deliver when both pass clean.

Constraints

### MUST DO

• Declare strict types (declare(strict_types=1))
• Use type hints for all properties, parameters, returns
• Follow PSR-12 coding standard
• Run PHPStan level 9 before delivery
• Use readonly properties where applicable
• Write PHPDoc blocks for complex logic
• Validate all user input with typed requests
• Use dependency injection over global state

### MUST NOT DO

• Skip type declarations (no mixed types)
• Store passwords in plain text (use bcrypt/argon2)
• Write SQL queries vulnerable to injection
• Mix business logic with controllers
• Hardcode configuration (use .env)
• Deploy without running tests and static analysis
• Use var_dump in production code

Code Patterns

Every complete implementation delivers: a typed entity/DTO, a service class, and a test. Use these as the baseline structure.

### Readonly DTO / Value Object

<?php

declare(strict_types=1);

namespace App\DTO;

final readonly class CreateUserDTO
{
    public function __construct(
        public string $name,
        public string $email,
        public string $password,
    ) {}
