Php yii2 cron给出的错误为；“未找到PDO”；

我在yii2中运行的应用程序很好。我创建了一个命令控制器/commands/TestController

<?php

namespace app\commands;

use app\models\UserProfile;
use yii\console\Controller;
use app\controllers\AppController;
/**
 * Test controller
 */
class TestController extends Controller
{

    public function actionIndex()
    {
        echo "cron service running";
    }

    public function actionSendBirthdaySms()
    {
        $userProfile = UserProfile::find()
            ->where('MONTH(dob) = MONTH(DATE(NOW()))')
            ->andWhere('DAY(dob) = DAY(NOW()) ')
            ->with('user')
            ->asArray()
            ->all();

        foreach($userProfile as $item){
            $birthdayMessage = "Happy Birthday " . $item['user']['username'];
            //to send sms
            $this->_send_cron_sms($item['mobile'], $birthdayMessage);
        }
    }

我还尝试了查询生成器，但它也没有帮到我。

我通过在php.ini文件中添加这两个扩展名解决了这个问题

extension=pdo.dll
extension=pdo_mysql.dll

我已经问过同样的问题了

extension=pdo.dll
extension=pdo_mysql.dll
