Update database that has same key with using a new different values

Lets say I have a table like this,

|id|area_id|area_values|
|1 |12     |value 1    |
|2 |12     |value 2    |
|3 |12     |value 3    |
|4 |01     |value 4    |

and I would like to update only those that have an area of 12. My new values is an array $values = ['newvalue1,'newvalue2',newvalue3'];

I have tried using array_map like this.

$ids = Area::where('area_id', 12)->pluck()->toArray();
array_map(function ($id) {
   array_map(function($areaValue){
     Area::find($id)->update(['area_values' => $areaValue]);
   }, $values);
}, $ids)

But the problem I encountered was it's being updated with only the first value of the new array, which is newValue1

What is the best approach on doing that?
