You are fetching array by using get. Replace these two lines with your codes and check. It will fetch only field data values.
$from_date = Experience::
where('user_id','=',$user_id)
->orderBy('exp_from_date','desc')
->take(1)
->pluck('exp_from_date')[0];
$to_date = Experience::
where('user_id','=',$user_id)
->orderBy('exp_to_date','desc')
->take(1)
->pluck('exp_to_date')[0];
Once check this documentation for details about pluck.
