Core / View / TestView.php：

<?php

  namespace Core\View;
  use Core\Components as Components;

  class TestView
  {

    public function renderView()
    {
      $Component=Components\TestComponent();
      echo $Component->renderComponent();
    }

  }

?>

  namespace Core\Components;

  class TestComponent
  {

    public function renderComponent()
    {
      echo "Core component here."
    }

  }

?>

---

App / Components / TestComponent.php：

<?php

  namespace App\Components;

  class TestComponent extends \Core\Components\TestComponent
  {

    public function renderComponent()
    {
      echo "App component here."
    }

  }

?>

<?php

  use App\Components as Components;

是否有任何合适的方法来获取上述应用以在此处呈现“ App组件”-即，让扩展类使用扩展文件中的命名空间？还是通过工厂功能实现此目标的唯一方法？
