好些个action中的代码是重复的，应该怎么优化调用呢？让代码更加简化 [ 求助交流 ]

	 public function actionOrder($id=1)
   {
        $query = Km1::find();
        $count = $query->count();
        $pager = new Pagination(['totalCount' => $count, 'pageSize' => '1']);
        $model = $query->offset($pager->offset)->limit($pager->limit)->all();
        //评论部分
        $id = $model[0]->courid;
        $comments = new Km1Comments();
        if($comments->load(Yii::$app->request->post()) && $comments->saveComments() ){
            return $this->refresh();
        }
        $findcomment = Km1Comments::find()->where("cour_id=:id",[":id"=>$id])->orderBy(['order_id'=>SORT_DESC,'created_time'=>SORT_DESC]);
        $pages = new Pagination(['totalCount' => $findcomment->count(), 'pageSize' => '5']);
        $discuss = $findcomment->offset($pages->offset)->limit($pages->limit)->all();

        $title = '顺序练习';
        //下一题
        $url =  Yii::$app->request->getHostInfo().Yii::$app->request->url.'?page=2&per-page=1';
        $this->layout = 'practice';
        return $this->render('practice',['courses' => $model, 'pager' => $pager,'count'=>$count,'title'=>$title,'comments'=>$comments,'discuss'=>$discuss,'pages'=>$pages,'url'=>$url]);
	  }

下面的另外一个方法

   public function actionRander($id=1)
    {
        $query = Km1::find();
        $count = $query->count();
        $arr = $query->select(['courid'])->column();
        $pager = new Pagination(['totalCount' => $count, 'pageSize' => '1']);

        $result = array_rand($arr,1);
        $model = Km1::findAll($result);

        //评论部分
        $id = $model[0]->courid;
        $comments = new Km1Comments();
        if($comments->load(Yii::$app->request->post()) && $comments->saveComments() ){
            return $this->refresh();
        }
        $findcomment = Km1Comments::find()->where("cour_id=:id",[":id"=>$id])->orderBy(['order_id'=>SORT_DESC,'created_time'=>SORT_DESC]);
        $pages = new Pagination(['totalCount' => $findcomment->count(), 'pageSize' => '5']);
        $discuss = $findcomment->offset($pages->offset)->limit($pages->limit)->all();

        $title = '随机练习';
        //下一题
        $url =  Yii::$app->request->getHostInfo().Yii::$app->request->url.'?page=2&per-page=1';
        $this->layout = 'practice';
        return $this->render('practice',['courses' => $model, 'pager' => $pager,'count'=>$count,'title'=>$title,'comments'=>$comments,'discuss'=>$discuss,'pages'=>$pages,'url'=>$url]);
    }

考虑到有多个这种方法，希望能做一个模板，然后进行调用，这样代码的数量会简化很多。只是网上找了好久都没找到类似的简化方法。。
