适用于创建相同类型的模型类能使代码更加健壮
举个栗子：车Car --> 奥迪，福特，宝马... 我们要造一辆

重要的是我们不需要引入所有相关类，我们只需要引入一个工厂类即可

interface Car{public function makeCircle();public function makeBody();public function makeEngine();public function makeDecoration();}class Audi{public function makeCircle(){    echo 'make Audi Circle';}public function makeBody(){    echo 'make Audi Body';}public function makeEngine(){    echo 'make Audi Engine';}public function makeDecoration(){    echo 'make Audi Decoration';}public function makeAuto(){}}class Ford{public function makeCircle(){    echo 'make Audi Circle';}public function makeBody(){    echo 'make Audi Body';}public function makeEngine(){    echo 'make Audi Engine';}public function makeDecoration(){    echo 'make Audi Decoration';}public function makeHandle(){}}class BMW{public function makeCircle(){    echo 'make BMW Circle';}public function makeBody(){    echo 'make BMW Body';}public function makeEngine(){    echo 'make BMW Engine';}public function makeDecoration(){    echo 'make BMW Decoration';}public function makeAll(){}}class CarFactory {static public function create($class,$params){if(!class_exists($class)){throw new Exception("class not existis!");}return new $class($params);}}$audi = CarFactory::create('Audi'，’15w‘);$audi->makeCircle();$bmw = CarFactory::create('BMW'，’100w‘);$bmw->makeAll();
