How to add more data to an object?

Question

Yii

Good afternoon,
I need to get such an array

[
    0 => [
        1 => app\models\UserModel#1
        (
            [yii\db\BaseActiveRecord:_attributes] => [
                'id' => '2199'
                'created' => '2015-12-14 13:12:51'
                'modified' => '2015-12-14 13:12:51'
                'days' => '1'
                'xxx_id' => [
                    0 => 19
                    1 => 20
                ]
                'is_active' => 1
            ]
            [yii\db\BaseActiveRecord:_oldAttributes] => [
                'id' => '2199'
                'created' => '2015-12-14 13:12:51'
                'modified' => '2015-12-14 13:12:51'
                'days' => '1'
                'xxx_id' => '20'
                'is_active' => 1
            ]
            [yii\db\BaseActiveRecord:_related] => []
            [yii\base\Model:_errors] => null
            [yii\base\Model:_validators] => null
            [yii\base\Model:_scenario] => 'default'
            [yii\base\Component:_events] => []
            [yii\base\Component:_behaviors] => []
        )
        2 => app\models\UserModel#2
        (
            [yii\db\BaseActiveRecord:_attributes] => [
                'id' => '2183'
                'created' => '2015-12-14 13:12:51'
                'modified' => '2015-12-14 13:12:51'
                'days' => '2'
                'xxx_id' => '1'
                'is_active' => 1
            ]
            [yii\db\BaseActiveRecord:_oldAttributes] => [
                'id' => '2183'
                'created' => '2015-12-14 13:12:51'

                'xxx_id' => '1'
                'is_active' => 1
            ]
            [yii\db\BaseActiveRecord:_related] => []
            [yii\base\Model:_errors] => null

            [yii\base\Component:_events] => []
            [yii\base\Component:_behaviors] => []
        )
        3 => app\models\UserModel#3
        (....)

How to do it in foreach

$models = UserModel::findAll(['user_id' =>  \Yii::$app->user->identity->getId()]);
        foreach ($models as $key => $value) {
            $model[$value->days] = $value;
//            $model[$value->days]->xxx_id[] = $value->xxx_id; - так не пашет
            }
//        $model[1]->availability_id = ['19', '20'];  -- мне надо вот так добавить только в фориче по каждому

// $model[1]->availability_id = ['19', '20']; -- I need to add like this only in the forich for each

Answer 1

You iterate over an array of $models objects, and in a loop you assign a value to some $model, i.e. $model is not defined at all. This is the first. Secondly, if the found records are needed not in the form of objects of the UserModel class, but in the form of arrays, use asArray () (please google it yourself), and of course it would not be bad to make sure that the elements were found at all before using foreach.
