Assalomu aleykum, in practice, alerts will be in view files, you should use the following pattern

Controller/method

public function actionIndex()
{
    $numero = Yii::$app->db
        ->createCommand("SELECT cantidad FROM productos WHERE 'nombre' = 'paco'")
        ->queryScalar();

    $alertMessage = null;
    if (($numero) <50){
        $alertMessage = 'Falta Stock en paco';
    }
    return $this->render('index',['alertMessage' => $alertMessage]);
}

View file index.php

<?php
/**
* @var string|null $alertMessage
*/
?>
....
<?php if ($alertMessage): ?>
<?php echo  Alert::widget([
     'options' => [
       'class' => 'alert',
     ],
     'body' => $alertMessage
   ]);
?>
<?php endif; ?>
....
