有些情况下我们需要根据不同的选择逻辑提供不同的构造工厂，而对于多个工厂而言需要一个统一的抽象工厂：
<?phpclass System{}class Soft{}class MacSystem extends System{}class MacSoft extends Soft{}class WinSystem extends System{}class WinSoft extends Soft{}/** * AbstractFactory class[抽象工厂模式] * @author ITYangs<ityangs@163.com> */interface AbstractFactory { ???public function CreateSystem(); ???public function CreateSoft();}class MacFactory implements AbstractFactory{ ???public function CreateSystem(){ return new MacSystem(); } ???public function CreateSoft(){ return new MacSoft(); }}class WinFactory implements AbstractFactory{ ???public function CreateSystem(){ return new WinSystem(); } ???public function CreateSoft(){ return new WinSoft(); }}//@test:创建工厂->用该工厂生产对应的对象//创建MacFactory工厂$MacFactory_obj = new MacFactory();//用MacFactory工厂分别创建不同对象var_dump($MacFactory_obj->CreateSystem());//输出：object(MacSystem)#2 (0) { }var_dump($MacFactory_obj->CreateSoft());// 输出：object(MacSoft)#2 (0) { }//创建WinFactory$WinFactory_obj = new WinFactory();//用WinFactory工厂分别创建不同对象var_dump($WinFactory_obj->CreateSystem());//输出：object(WinSystem)#3 (0) { }var_dump($WinFactory_obj->CreateSoft());//输出：object(WinSoft)#3 (0) { }PHP设计模式 - 抽象工厂模式
