|
* 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' => [ |
|
* 1, |
|
* 2, |
|
* ], |
