And a notice that you are "Trying to get property of non-object". If
you don't see this you should probably turn notices on since they can
help a lot.
You need to avoid accessing $key->option when the $key is 'all'.

It's possible that you want
$newarray[array_keys($obj->option)[0]] = array_values($obj->option)[0];
but, if not, please give the actual values you'd like to see in
$newarray. Also note that you will have to deal with the 'all' case as
I mentioned above.

This bit I don't follow. You can do that for every array.
