    public function setName($name) {
        if ($this->validateAttribute($name)) {
            $this->name = $name;
        } else {
            echo "Invalid name format";
        }
    }

    private function validateAttribute($attribute) {
        // Add your validation logic here
        // For example, checking if the attribute is not empty
        if (!empty($attribute)) {
            return true;
        } else {
            return false;
        }
    }
}

$user = new User();
$user->setName("John"); // Valid name
$user->setName(""); // Invalid name format
