How to update a list of data using Relationships in Laravel?

Question

Laravel

Hello!

In Laravel, I create a list of data using hasMany :

$user = User::find($id);
        $user->phones()->createMany($myArray);

What method can be used to update that list in Laravel?
I look at the docks, there is no updateMany method there. It is necessary to add a new data list $myNewArray to phones(), at the same time, so that those elements that are in the new list and already in the table are not added to the table, and those remaining elements that are present in the table, but not in the new list, remove from the table, well, add all new elements to the table.
