PHP is responding that the variable has not been defined (Undefined variable). Use isset to verify that the variable was created. 

if( isset( $nome ) )
{
    if( $nome == '' OR strlen( $nome ) < 4 )
    {
        echo 'menor que 4';
    }
}

OBS 1. $nome == '' and $nome === '' have a different result depending on the typing of the variable, see operators .

OBS2. strlen does not return the exact string size when it has special characters. Prefer to use mb_strlen to work with strings.

If you want to get a form field, use $_POST['nome_do_campo'] . NEVER use extract in form data. Imagine the scenario below with a user injecting a <input name="pdo" /> 

<form method="post">
     <input name="pdo" />
</form>

$PDO = new PDO( ... );
extract($_POST);

You will lose your PDO instance.
