Use of undefined constant

Good was with the same problem of this question, gave an answer to use define('ROOT_PATH', dirname(__FILE__));, (my problem without using this solution) but in mine it does not work.
the following error appears:

Warning: Use of undefined constant directory-assumed 'Directory' (this will throw an Error in a future version of PHP) in C:\wamp64\www\php_pdo\view\sign-in.php online 27

Index.php:

    <php   
    define('DIRETORIO', dirname(__DIR__));
    ...

Sign-in.php:

<?php
    if($_POST){
        $usuario = filter_input(INPUT_POST, 'usuario', FILTER_SANITIZE_STRING);
        $senha = filter_input(INPUT_POST, 'senha', FILTER_SANITIZE_STRING);

        require_once DIRETORIO . '/controller/logincontroller.php'; // linha 27
        LoginController::logar($usuario, $senha);

    }

I tried to do what this answer suggests, but it did the same.

Sign-in.php

<?php
    if($_POST){
        $usuario = filter_input(INPUT_POST, 'usuario', FILTER_SANITIZE_STRING);
        $senha = filter_input(INPUT_POST, 'senha', FILTER_SANITIZE_STRING);
        require_once '../index.php';
        require_once DIRETORIO . '/controller/logincontroller.php'; // linha 27
        LoginController::logar($usuario, $senha);

    }
