php基础求助~~~~
有个问题是关于继承和接口的?~~~~~~~

我有个class person implements ispeak{public function speak(){echo "人说话";}}类,
鸟类class bird implements ispeak{public function speak(){echo "鸟叫";}}类 
 接口ispeak{public function speak();}

我一个艺人类 yrPerson extends person {} 
因为艺人可以学鸟叫 我现在想让艺人也可以鸟叫 但不要重复写代码public function speak(){echo "鸟叫";}


高手给讲讲!!!!急呀 经理总说我代码重复率太高了~~~~~


------解决方案--------------------
忘了要继承person类,小改一下

PHP code
class yrPerson extends person{    //添加口技方法...    public function show($a){        $func=Factory::func($a);        return $func->speak();    }}$person=new yrPerson();$person->speak();        //自己说话$person->show('dog');    //学狗叫$person->show('bird');    //学鸟叫//接着学...<div class="clear">
                 
              
              
        
            </div>
