只想问一下简单的facory模式。
我读了描述这些类和接口的文章:
interface Door
{
public function getWidth(): float;
public function getHeight(): float;
}
class WoodenDoor implements Door
{
protected $width;
protected $height;
public function __construct(float $width, float $height)
{
$this->width = $width;
$this->height = $height;
}
public function getWidth(): float
{
return $this->width;
}
public function getHeight(): float
{
return $this->height;
}
}
那里也推了工厂课:
class DoorFactory
{
public static function makeDoor($width, $height): Door
{
return new WoodenDoor($width, $height);
}
}
有什么不同:
$ door = DoorFactory:makeDoor(100,200);
和
$ door = new WoodenDoor(100,200); ?
在此示例中,我无法区分差异和意义。
感谢您的明智回答。
