关于php对象依赖的介绍

1 action = $a; 17 } 18 //通过方法访问类中的私有属性 19 public function getaction() 20 { 21 $this->action->playing();22 } 23 } 24 25 $ply = new play(); 26 $vid = new video($ply); 27 $vid->getaction();//输出I can playing

action = $a; } //通过方法访问类中的私有属性 public function getaction() { return $this->action->playing(); } }$ply = new play();//实例化play类后面做参数 $vid = new video(); $vid->action = $ply;//当访问video为定义的属性值时会调用__set()方法(不懂的可以看看php的魔术方法) $vid->getaction();//输出I can playing
