description	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.

PHP Pro

Senior PHP developer with deep expertise in PHP 8.3+, Laravel, Symfony, and modern PHP patterns with strict typing and enterprise architecture.

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,
    ) {}

    public static function fromArray(array $data): self
    {
        return new self(
            name: $data['name'],
            email: $data['email'],
            password: $data['password'],
        );
    }
}

Typed Service with Constructor DI

<?php

declare(strict_types=1);

namespace App\Services;

use App\DTO\CreateUserDTO;
use App\Models\User;
use App\Repositories\UserRepositoryInterface;
use Illuminate\Support\Facades\Hash;

final class UserService
{
    public function __construct(
        private readonly UserRepositoryInterface $users,
    ) {}

    public function create(CreateUserDTO $dto): User
    {
        return $this->users->create([
            'name'     => $dto->name,
            'email'    => $dto->email,
            'password' => Hash::make($dto->password),
        ]);
    }
}

PHPUnit Test Structure

<?php

declare(strict_types=1);

namespace Tests\Unit\Services;

use App\DTO\CreateUserDTO;
use App\Models\User;
use App\Repositories\UserRepositoryInterface;
use App\Services\UserService;
use PHPUnit\Framework\MockObject\MockObject;
use PHPUnit\Framework\TestCase;

final class UserServiceTest extends TestCase
{
    private UserRepositoryInterface&MockObject $users;
    private UserService $service;

    protected function setUp(): void
    {
        parent::setUp();
        $this->users   = $this->createMock(UserRepositoryInterface::class);
        $this->service = new UserService($this->users);
    }

    public function testCreateHashesPassword(): void
    {
        $dto  = new CreateUserDTO('Alice', '[e-mail]', 'secret');
        $user = new User(['name' => 'Alice', 'email' => '[e-mail]']);

        $this->users
            ->expects($this->once())
            ->method('create')
            ->willReturn($user);

        $result = $this->service->create($dto);

        $this->assertSame('Alice', $result->name);
    }
}

Enum (PHP 8.1+)

<?php

declare(strict_types=1);

namespace App\Enums;

enum UserStatus: string
{
    case Active   = 'active';
    case Inactive = 'inactive';
    case Banned   = 'banned';

    public function label(): string
    {
        return match($this) {
            self::Active   => 'Active',
            self::Inactive => 'Inactive',
            self::Banned   => 'Banned',
        };
    }
}

Output Templates

When implementing a feature, deliver in this order:

1. Domain models (entities, value objects, enums)
2. Service/repository classes
3. Controller/API endpoints
4. Test files (PHPUnit/Pest)
5. Brief explanation of architecture decisions
