}

class SubmitButton implements Button {
    public function render() {
        echo 'Render Submit Button';
    }
}

class ResetButton implements Button {
    public function render() {
        echo 'Render Reset Button';
    }
}

class SubmitFactory implements GUIFactory {
    public function createButton() {
        return new SubmitButton();
    }
}

class ResetFactory implements GUIFactory {
    public function createButton() {
        return new ResetButton();
    }
}

$submitFactory = new SubmitFactory();
$button = $submitFactory->createButton();
$button->render();

echo '<br/>';

$resetFactory = new ResetFactory();
$button = $resetFactory->createButton();
$button->render();
