Yii2 display serialized data in gridview - php

Question

I have some data stored in serialized format.
I can pull the data and show it in view like this for the logged in user:
$user_id = Yii::$app->user->identity->id;
$kids=unserialize($model->kids);
$children =\app\models\UserChildren::find()->where(['user_id' =>$user_id])->andwhere(['id'=>$kids])->all();
?>
<?php foreach ($children as $child): ?>
<table class="table table-bordered table-hover">
<tr>
<th><?php echo Yii::t('app', 'Kids Name')?> : </th>
<td><?php echo $child->child_name?> </td>
<th><?php echo Yii::t('app', 'Kids Birth Date')?> : </th>
<td><?php echo $child->child_birth_date?> </td>
<th><?php echo Yii::t('app', 'Kids Gender')?> : </th><td><?php echo $child->child_gender?> </td>
</tr>
</table>
<?php endforeach; ?>
The kids data is stored in order table like this, which is linked to the table userchildren.
s:0:"";
a:4:{i:0;s:2:"10";i:1;s:2:"11";i:2;s:2:"25";i:3;s:2:"26";}
a:2:{i:0;s:2:"10";i:1;s:2:"11";}
I have tried to display the same in gridview, but couldn't make out how I can achieve this:
like for example if I am using
[
'label'=> 'Child',
'value' => function($data){
return $data->order->kids;
}
],
I am getting the same data as I have shown.
I also tried foreach, but I am getting invalid argument foreach.

Answer 1

Not sure If I have done correctly, but it appears to have the correct data.
The code I am using is like below:
[
'label'=> 'Child',
'value' => function($data){
$kids=((unserialize($data->order->kids)));
$children1=ArrayHelper::map(\app\models\UserChildren::find()->where(['id'=>$kids])->all(),'id','child_name');
return implode(', ',$children1);
}
],
