德国酒店
class Hotel
{
private $dbSocket;
public function setSocket(DBSocketInterface $dbSocket)
{
$this->dbSocket = $dbSocket;
}

}
}
适配器(插头转换 接口转换)
class SocketAdatper implements DBSocketInterface
{
private $gbSocket;
public function __construct(GBSocketInterface $gbSocket)
{
$this->gbSocket = $gbSocket;
}
public function powerWithTwoRound()
{
$this->gbSocket->powerWithThreeRound;
}
}
测试
$gbSocket = new GBSocket();
$hotel = new Hotel();
$socketAdapter = new SocketApapter($gbSocket);
$hotel->setSocket($socketApapter);
$hotel->charge();
