How to display data from related table using Arrayelper::index?

The problem I have is that I was able to bring the data below are grouped by date. Just do not understand how to display data from related data
In the controller
$comment = Comment::find()->addSelect(['DATE(date) as just_date','TIME(date) as time','comment','id_user'])->where(['id_zakaz' => $id])->asArray()->all();
 $comment = ArrayHelper::index($comment, null, 'just_date');

In the view
<?php foreach ($comment as $key=-->$com){
 echo Yii::$app->formatter->asDate($key, 'php:j M Y').'<br>';
 foreach ($com as $value=>$name){
 echo Yii::$app->formatter->asTime(ArrayHelper::getValue($name, 'time'), 'php:H:i').' '.ArrayHelper::getValue($name, 'comment').' '.ArrayHelper::getValue($name, 'id_user').'<br>';
 } ?>

That is, I need id_user->idUser->name. Just a thought I had to make another request, it would be logical in the query to make another query

load related data by using joinWith and then choose what You need
And if you use with() it does not matter what is used it is not joinWith? - Waylon_Kub commented on June 14th 19 at 20:46
for Your task it's best to use joinWith - bryana.Renn commented on June 14th 19 at 20:49
