How to get values ​​of all fields from DB in related tables?

Question

Yii

Please tell me how to be?
I have a table with products, properties and another table links them.
I want to do as in the video from Maxim Timofeev about the Select2 extension.
In the video he selects via ArrayHelper:map i.e. key and value.
Everything would be fine, but I need this drop-down list to contain not just "id" and "name", but also the value of other fields. How can I do that?

Answer 1

If I understand the problem correctly, then:

ArrayHelper::map($array, 'id', function ($element){
    return $element['name']. ' ' . $element['paramName'];
});
