            [UpdatedBy] => 0
        )
    );

what is the best way to do this , thank you very much…………..

Answer 1

You can easily use array_map to do this, with unset to remove the index. Example:

$your_array = array_map(
  function($array) {
     unset($array['ProfilePrivacySettingDefaultID']);
  },
  $your_array
);
