yii ActiveRecord 输出运行sql语句

代码如下

<?php

namespace appcontrollers;

use Yii;
use yiiwebController;
use yiimodels;
use appmodelsUsers;

class UserController extends yiiwebController
{
    public function actionIndex(){
        $user= new Users;

        $data=$user::find()->joinWith("userGroup")->asArray()->all();
        echo $user::find()->joinWith("userGroup")
				        ->createCommand()
				        ->getRawSql();
        echo "<pre>";
        print_r($data);
    }
    

}
