如何在PHP中使用OOP框架

composer create-project --prefer-dist laravel/laravel {项目名称}

Route::get('/user', '[email protected]');

class UserController extends Controller
{
    public function index()
    {
        $users = User::all();

        return view('user.index', ['users' => $users]);
    }
}

class User extends Model
{
    // Define the table name
    protected $table = 'users';
}

@foreach ($users as $user)
    {{ $user->name }}
@endforeach

composer create-project symfony/skeleton {项目名称}

$routes->get('/user', 'AppControllerUserController::index');

class UserController extends AbstractController
{
    public function index(EntityManagerInterface $entityManager)
    {
        $users = $entityManager->getRepository(User::class)->findAll();

        return $this->render('user/index.html.twig', ['users' => $users]);
    }
}

class User
{
    
    private $id;
    
    
    private $name;
    
    // ...
}

{% for user in users %}
    {{ user.name }}
{% endfor %}

$route['user'] = 'UserController/index';

class UserController extends CI_Controller
{
    public function index()
    {
        $this->load->model('User_model');
        $data['users'] = $this->User_model->get_users();

        $this->load->view('user/index', $data);
    }
}

class User_model extends CI_Model
{
    public function get_users()
    {
        $this->db->select('*');
        $this->db->from('users');
        $query = $this->db->get();
        
        return $query->result();
    }
}

<?php foreach ($users as $user) { ?>
    <?php echo $user->name; ?>
<?php } ?>
