* Object that represents the removal of array value while performing [[ArrayHelper::merge()]].
*
* Usage example:
*
* ```php
* $array1 = [
* 'ids' => [
* 1,
* ],
* 'validDomains' => [
* 'example.com',
* 'www.example.com',
* ],
* ];
*
* $array2 = [
* 'ids' => [
* 2,
* ],
* 'validDomains' => new \yii\helpers\UnsetArrayValue(),
* ];
*
* $result = \yii\helpers\ArrayHelper::merge($array1, $array2);
* ```
*
* The result will be
*
* ```php
* [
* 'ids' => [
