Secrets of the mainstream PHP8 framework that you must know

#PHP8 mainstream framework revealed: you must understand these frameworks!

With the release of PHP8, many new features and improvements make PHP a more powerful and efficient programming language. This has also led to many mainstream frameworks successively updating and adapting to the changes in PHP8. In this article, we will explore some of the mainstream PHP8 frameworks worth paying attention to and provide some specific code examples. These frameworks not only make it easier for you to develop PHP applications, but also take full advantage of PHP8.

1. Laravel 8
   Laravel is one of the most popular PHP frameworks currently, and the updated version under PHP8, Laravel 8, makes full use of the new features of PHP8. The most notable of these are Jetstream and Livewire. Jetstream is Laravel's new user authentication and management scaffolding, which uses Tailwind CSS as the default front-end framework. Livewire is a front-end development framework similar to Vue.js and React. It uses Blade templates and can write interactive components directly in PHP.

Code sample:

// Jetstream用户注册
use IlluminateFoundationAuthUser;

class RegisterController extends Controller
{
    public function store(Request $request)
    {
        $validator = Validator::make($request->all(), [
            'name' => ['required', 'string', 'max:255'],
            'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
            'password' => ['required', 'confirmed', Password::defaults()],
        ]);

        if ($validator->fails()) {
            throw new ValidationException($validator);
        }

        User::create($validator->validated());

        return redirect(RouteServiceProvider::HOME);
    }
}

// Livewire数据绑定
use LivewireComponent;

class Counter extends Component
{
    public $count = 0;

    public function increment()
    {
        $this->count++;
    }

    public function decrement()
    {
        $this->count--;
    }

    public function render()
    {
        return view('livewire.counter');
    }
}

2. Symfony 5
   The Symfony framework has also been updated in time to adapt to the new version of Symfony 5 for PHP8. Symfony 5 brings many new features, such as route auto-registration, caching improvements, form themes, etc. In addition, Symfony 5 also improves code readability and maintainability by using a new property injection mechanism and property inference.

Code sample:

// 路由自动注册
use SymfonyComponentRoutingAnnotationRoute;

#[Route('/user')]
class UserController extends AbstractController
{
    #[Route('/', name: 'user_list')]
    public function list(): Response
    {
        // ...
    }

    #[Route('/{id}', name: 'user_show')]
    public function show(int $id): Response
    {
        // ...
    }
}

// 属性注入和属性推断
class HomeController extends AbstractController
{
    private UserRepository $userRepository;

    public function __construct(UserRepository $userRepository)
    {
        $this->userRepository = $userRepository;
    }
    
    // ...
}

3. Yii 3
   Yii is another popular PHP framework, and the Yii 3 version has also been released, fully compatible with PHP8. Yii 3 introduces a new DI container and event mechanism, making application component management more flexible and efficient. In addition, Yii 3 also strengthens support for RESTful APIs and Microservices, providing better performance and security.

Code sample:

// DI容器和事件机制
class UserController
{
    private UserRepository $userRepository;

    public function __construct(ContainerInterface $container)
    {
        $this->userRepository = $container->get(UserRepository::class);
    }

    public function create(Request $request): Response
    {
        // ...

        $this->userRepository->save($user);

        $event = new UserCreatedEvent($user);
        $this->eventDispatcher->dispatch($event);

        // ...
    }
}

// RESTful API支持
class UserController extends Controller
{
    public function actionIndex(): array
    {
        return $this->userRepository->findAll();
    }

    public function actionView(string $id): ?User
    {
        return $this->userRepository->findOneById($id);
    }

    public function actionCreate(Request $request): void
    {
        $user = new User();

        $user->load($request->getBodyParams(), '');
        $this->userRepository->save($user);
    }
}

The above are a few mainstream frameworks worthy of attention under PHP8. They take full advantage of the new features and improvements of PHP8 to provide a more efficient, flexible and secure development method. By understanding and using these frameworks, you can develop PHP applications more easily and take full advantage of PHP8. Whether you are a newbie or an experienced developer, these frameworks are worth a try!
