cat.php

<?php

namespace vendor\animal;
use \yii\base\Component;//组件
use \yii\base\Event;//
class myEvent extends Event{
 public $message;
}
class Cat extends Component{
 public function shout(){

Dog.php

 }
}

Mouse.php

<?php

class Mouse{
 public function run($e)

}

controllers/AnimalController.php 调用第三方类库
