Organize phpDoc for __get property where property is an instance of a class, how?

Question

PHP

Hello everyone!
Something does not come out correctly to write phpDoc so that autocomplete would work in phpstorm.
Below is the code itself.
P.S. The code is not mine, I don’t want to rewrite it, since there are many projects on this engine.
Base.php

<?php
/**
 * Class Base
 * @property $config
 * @property $request
 * @property $db
 */
Class Base {

   
  private $classes = array(
    'config'     => 'Config',
    'request'    => 'Request',
    'db'         => 'Database'
  );
  
  private static $objects = array();
  
  public function __get($name)
  {
    // Если такой объект уже существует, возвращаем его
    if(isset(self::$objects[$name]))
    {
      return(self::$objects[$name]);
    }

    // Если запрошенного API не существует - ошибка
    if(!array_key_exists($name, $this->classes))
    {
      return null;
    }

    // Определяем имя нужного класса
    $class = $this->classes[$name];

    // Подключаем его
    include_once(dirname(__FILE__).'/'.$class.'.php');

    // Сохраняем для будущих обращений к нему
    self::$objects[$name] = new $class();

    // Возвращаем созданный объект
    return self::$objects[$name];
  }
}

config.php

<?php

require_once('Base.php');

class Config
{

  private $vars = array();
  public function __construct()
  {
    //....
  }
  //....
}

Database.php

<?php
require_once('Base.php');

class Database extends Base
{
  private $mysqli;
  private $res;

  public function __construct()
  {
    parent::__construct();
    $this->connect();
  }
  
  public function connect() {/*....*/}
  
  public function query() {/*....*/}
  
  public function placehold() {/*....*/}
  
  //....
}

Request.php

<?php
require_once('Base.php');

class Request extends Base
{

  public function __construct()
  {
    parent::__construct();

    //....

  }
  
  public function method($method = null) {/*....*/}
  
  private function stripslashes_recursive($var) {/*....*/}
  //....
  
}

Thank you for your attention, I will be grateful for your help.

Answer 1

/**
 * Class Base
 * @property Config $config
 * @property Request $request
 * @property Database $db
 */

Or I didn't quite understand what you are asking.
