# PHP Fullstack Engineer

Skill para desenvolvimento PHP moderno seguindo padrões Descomplicar®.

## Quando Usar

- Criar APIs RESTful
- Implementar autenticação (JWT, OAuth, Sanctum)
- Desenvolver service classes
- Refactorizar código legacy
- Integrar com APIs externas

## Protocolo Obrigatório

### 1. Pesquisa Inicial
```
mcp__memory-supabase__search_memories "[keywords php/laravel]"
mcp__wikijs__search_pages "[framework] best practices"
mcp__context7__get-library-docs para documentação actualizada
```

### 2. Quality Gate 70+
- Funções < 50 linhas
- Classes < 500 linhas
- Cyclomatic complexity < 10
- PHPDoc em todas as funções públicas
- Type hints em parâmetros e retornos

### 3. Assinatura Obrigatória
```php
<?php
/**
 * [Nome do Ficheiro/Classe]
 *
 * @author Descomplicar® Crescimento Digital
 * @link https://descomplicar.pt
 * @copyright 2025 Descomplicar®
 */
```

## Padrões de Código

### PHP 8.1+ Features
```php
// Typed properties
private readonly string $name;

// Constructor promotion
public function __construct(
    private readonly ProductService $service
) {}

// Enums
enum Status: string {
    case Active = 'active';
    case Inactive = 'inactive';
}

// Match expression
$result = match($status) {
    Status::Active => 'Activo',
    Status::Inactive => 'Inactivo',
};

// Named arguments
$this->service->create(
    name: $name,
    price: $price
);
```

### PSR Standards
- **PSR-1**: Basic Coding Standard
- **PSR-4**: Autoloading
- **PSR-12**: Extended Coding Style
- **PSR-7**: HTTP Message Interface
- **PSR-15**: HTTP Handlers

## Segurança (OBRIGATÓRIO)

```php
// SQL - SEMPRE prepared statements
$stmt = $pdo->prepare("SELECT * FROM users WHERE id = ?");
$stmt->execute([$id]);

// Input validation
$email = filter_var($input, FILTER_VALIDATE_EMAIL);

// Output escaping
echo htmlspecialchars($output, ENT_QUOTES, 'UTF-8');

// Password hashing
$hash = password_hash($password, PASSWORD_ARGON2ID);

// CSRF em forms
<input type="hidden" name="_token" value="<?= csrf_token() ?>">
```

## Padrão Laravel

### Controller
```php
<?php

namespace App\Http\Controllers\Api;

use App\Http\Controllers\Controller;
use App\Http\Requests\StoreProductRequest;
use App\Http\Resources\ProductResource;
use App\Services\ProductService;
use Illuminate\Http\JsonResponse;

/**
 * ProductController - API de Produtos
 *
 * @author Descomplicar® Crescimento Digital
 * @link https://descomplicar.pt
 * @copyright 2025 Descomplicar®
 */
class ProductController extends Controller
{
    public function __construct(
        private readonly ProductService $productService
    ) {}

    public function index(): JsonResponse
    {
        $products = $this->productService->paginate();
        return ProductResource::collection($products)->response();
    }

    public function store(StoreProductRequest $request): JsonResponse
    {
        $product = $this->productService->create($request->validated());
        return (new ProductResource($product))
            ->response()
            ->setStatusCode(201);
    }
}
```

### Service
```php
<?php

namespace App\Services;

use App\Models\Product;
use App\Repositories\ProductRepository;
use Illuminate\Pagination\LengthAwarePaginator;

/**
 * ProductService - Lógica de negócio Produtos
 *
 * @author Descomplicar® Crescimento Digital
 * @link https://descomplicar.pt
 * @copyright 2025 Descomplicar®
 */
class ProductService
{
    public function __construct(
        private readonly ProductRepository $repository
    ) {}

    public function paginate(array $filters = []): LengthAwarePaginator
    {
        return $this->repository->paginate($filters);
    }

    public function create(array $data): Product
    {
        return $this->repository->create($data);
    }
}
```

### Repository
```php
<?php

namespace App\Repositories;

use App\Models\Product;
use Illuminate\Pagination\LengthAwarePaginator;

/**
 * ProductRepository - Acesso a dados Produtos
 *
 * @author Descomplicar® Crescimento Digital
 * @link https://descomplicar.pt
 * @copyright 2025 Descomplicar®
 */
class ProductRepository
{
    public function paginate(array $filters = []): LengthAwarePaginator
    {
        return Product::query()
            ->when($filters['category'] ?? null, fn($q, $cat) => $q->where('category_id', $cat))
            ->when($filters['active'] ?? null, fn($q, $active) => $q->where('active', $active))
            ->orderBy('created_at', 'desc')
            ->paginate($filters['per_page'] ?? 15);
    }

    public function create(array $data): Product
    {
        return Product::create($data);
    }
}
```

## Debugging PHP

### Xdebug

```php
// php.ini
zend_extension=xdebug.so
xdebug.mode=debug
xdebug.start_with_request=yes
xdebug.client_host=127.0.0.1
xdebug.client_port=9003
```

### Logging

```php
// Monolog exemplo
use Monolog\Logger;
use Monolog\Handler\StreamHandler;

$log = new Logger('app');
$log->pushHandler(new StreamHandler('logs/app.log', Logger::DEBUG));

$log->info('User logged in', ['user_id' => $userId]);
$log->error('Database error', ['exception' => $e->getMessage()]);
```

### Profiling

```bash
# Com Blackfire
blackfire run php script.php

# Com Xhprof
php -d extension=xhprof.so script.php
```

## Testes Unitários

### PHPUnit

```php
<?php

use PHPUnit\Framework\TestCase;

class ProductServiceTest extends TestCase
{
    private ProductService $service;

    protected function setUp(): void
    {
        $this->service = new ProductService(
            new InMemoryProductRepository()
        );
    }

    public function test_create_product(): void
    {
        $product = $this->service->create([
            'name' => 'Test Product',
            'price' => 99.99
        ]);

        $this->assertInstanceOf(Product::class, $product);
        $this->assertEquals('Test Product', $product->name);
    }
}
```

### Pest (alternativa moderna)

```php
<?php

test('creates product', function () {
    $product = app(ProductService::class)->create([
        'name' => 'Test',
        'price' => 99.99
    ]);

    expect($product)
        ->toBeInstanceOf(Product::class)
        ->name->toBe('Test');
});
```
