YII框架实现自定义第三方扩展操作示例

本文实例讲述了YII框架实现自定义第三方扩展操作。分享给大家供大家参考，具体如下：

cat.php

<?php
/**
 * Created by PhpStorm.
 * Date: 2016/5/25
 * Time: 15:23
 */
namespace vendoranimal;
use yiibaseComponent;//组件
use yiibaseEvent;//
class myEvent extends Event{
  public $message;
}
class Cat extends Component{
  public function shout(){
    echo "miao miao miao<br ";
    //$this- trigger('miao');//事件命名
    $me = new myEvent();
    $me- message = "hello my Event<br ";
    $this- trigger('miao',$me);
  }
}

Dog.php

<?php
/**
 * Created by PhpStorm.
 * Date: 2016/5/25
 * Time: 17:00
 */
namespace vendoranimal;
use frontendbehaviorsbehavior1;
use yiibaseComponent;//让一个类拥有接收行为的能力
class Dog extends Component{
  public function behaviors(){
    return [
      Behavior1::className(),
    ];
  }
  public function look()
  {
    echo "I am looking!<br ";
  }
}

Mouse.php

<?php
/**
 * Created by PhpStorm.
 * Date: 2016/5/25
 * Time: 15:23
 */
namespace vendoranimal;
class Mouse{
  public function run($e)
  {
    echo $e- message;
    echo "I am running!<br ";
  }
}

controllers/AnimalController.php 调用第三方类库

<?php
/**
 * Created by PhpStorm.
 * Date: 2016/5/25
 * Time: 15:27
 */
//YII事件绑定
namespace frontendcontrollers;
use yii;
use yiiwebController;
use vendoranimalCat;
use vendoranimalMouse;
use vendoranimalDog;
use yiibaseEvent;//类级别的事件绑定必须
use frontendbehaviorsBehavior1;//对象的混合
class AnimalController extends Controller{
  public function actionIndex(){
    $cat = new Cat();
    $mouse = new Mouse();
    $dog = new Dog();
    //对象级别的事件绑定
    $cat- on('miao',[$mouse,'run']);
    $cat- on('miao',[$dog,'look']);
//
//    $cat- off('miao',[$dog,'look']);//取消关注
    //类级别的事件绑定
//    Event::on(Cat::className(),'miao',[$mouse,'run']);//所有的老鼠都会监听这个miao事件
//    Event::on(Cat::className(),'miao',function(){
//      echo "miao event has triggerd!<br ";
//    });
    $cat- shout();
    //Yii::$app是YII实现的单例模式
//    Yii::$app- on(yiibaseApplication::EVENT_AFTER_REQUEST,function(){
//      echo "event after request";
//    });
  }
  public function actionBehavior()//类的混合
  {
    /*板块1
     * $dog = new Dog();
    $dog- look();
    $dog- eat();*/
    $dog=new Dog();
    $dog- trigger("wang");
  }
  public function actionObject()//对象的混合
  {
    $dog = new Dog();
    $behavior1 = new Behavior1();
    $dog- attachBehavior('beh1',$behavior1);//取个别名，防止冲突
    //$dog- detachBehavior('beh1');//移除对象
    $dog- eat();
  }
}
