Connecting Multiple Classes with the Use Command in OOP in PHP

If you need to connect several classes, each of them is connected with its own use command:

/users/page.php<?php
  namespace Users;
  use \Core\Admin\Data1; // connect the class
  use \Core\Admin\Data2; // connect the class
  
  class Page extends Controller
  {
    public function __construct()
    {
      $data1 = new Data1; // call simply by name
      $data2 = new Data2; // call simply by name
    }
  }
?>

php<?php
  namespace Project;
  
  class Test
  {
    public function __construct()
    {
      $model = new \Core\Admin\Model;
      $data  = new \Core\Users\Storage\Data;
    }
  }
?>
