/**抽象原型类
 * Class Prototype

abstract class Prototype
{
   abstract function cloned();
}

/**具体原型类
 * Class Plane
 */
class Plane extends Prototype
{

    public $color;

    function Fly()
    {
        echo 飞机飞啊飞!
;
    }

    function cloned()
    {
        return clone $this;
    }
}

//------------------------原型模式测试代码------------------
require_once ./Prototype/Prototype.php;

$plane1=new Plane();
$plane1->color=Blue;

$plane2=$plane1->cloned();

$plane1->Fly();
$plane2->Fly();

echo plane1的颜色为：{$plane1->color}
;
echo plane2的颜色为：{$plane2->color}
