php设计模式-工厂方法模式

<?php
header('Content-Type:text/html;charset=utf-8');
interface people{
    public function say();
}
// man类 继承people
class man implements people{
    public function say(){
        echo "man-1";
    }
}
// woman类 继承people
class woman implements people{
    public function say(){
        echo "woman-1";
    }
}

// 创建对象类
// 将对象的创建抽象成了一个接口
interface createPeople{
    public function create();
}
// 用于创建man对象的工厂类 继承createpeople
class FactoryMan implements createPeople{
    public function create(){
        return new man();
    }
}
// 用于创建woman对象的工厂类 继承createpeople
class FactoryWoman implements createPeople{
    public function create(){
        return new woman();
    }
}

// 具体操作类
class Client{
    public function test(){
        $factory = new FactoryMan();
        $man = $factory->create();
        $man->say();

        $factory = new FactoryWoman();
        $woman = $factory->create();
        $woman->say();
    }
}

$result = new Client;
$result->test();
