Ребята, привет. Помогите найти детскую ошибку, а то уже извелся весь...
делаю календарь, при добавлении елементов в существующий массив затираются предідущий елементы

$client = Client::find()->asArray()->where(['<', 'status', 4])->all();
        $shedule = [];

                    $shedule['room' . $model['room']] = [];
                }

                if (!array_key_exists(date('d.m.Y', strtotime($model['date_begin'])), $shedule['room' . $model['room']])) {
