How to correctly build a query in yii2 so that one record is taken from each category?

Question

Yii

Here is the request:

$query = self::find()->select('id, title, url, img, img_thumb, website_id')->where(['status' => 1])
                ->andWhere(['in', 'website_id', $array_websites])->limit($sum)->orderBy(new Expression('rand()'))->asArray()->all();

$array_websites - here are 10 IDs of different categories, it is necessary that the selection be one entry from each category.
What's the best way?
