當渲染 $members 數組并以 html 格式輸出此代碼時，該數組變為 0123456，而不是我在存儲庫中請求的值?？刂破鳎簆ublic function getMembers(UserRepository $userRepository){        $members = $userRepository->getAllMembers();        $entitiyManager=$this->getDoctrine()->getManager();           return $this->render('leaderboard/leaderboard_Rankings.html.twig',['members' => $members]);    }存儲庫：public function getAllMembers(): array     {        $entityManager = $this->getEntityManager();        $query = $entityManager->createQuery(            'SELECT m.mem_name, m.mem_surname, m.mem_id             FROM App\Entity\Member m            ORDER BY m.mem_name ASC'        );        // returns an array of Product objects        return $query->getResult();    }    /**     * @return User[] Returns an array of User objects     */HTML：<table><tr><td>   {% for key, item in members %}     {{ key }}{% endfor %}   </td>   <td>   {{members.mem_name}} //Does not work   </td>  </tr></table>錯誤是：Key "mem_name" for array with keys "0, 1, 2, 3, 4, 5, 6" does not exist.或者該值打印 0123456
