    //reg
    $errors = array();
    
    if(R::count('users', "email = ?", array($data['user_Email'])) > 0) {
        $errors[] = 'already reg';
    }
    
    if(empty ($errors)) {
        $user = R::dispense('users');
        $user->email = $data['user_Email'];
        $user->birthsday = $data['user_birthsday'];
        $user->password = password_hash($data['user_pass'], PASSWORD_DEFAULT);
        R::store($user);
    } else {
        $error = array_shift($errors);
        return $error;
    }
    $reg = R::findOne('users', 'email = ?', array($data['user_Email']));
    $_SESSION['reg_user'] = $reg; 
    header('Location: /other_page');
    die();
}
