The syntax $arrKstDB[$key]['kostenstellennr']['kostenstellenbez'] implies that we are accessing a nested array within the $arrKstDB array. It suggests that we are trying to retrieve the value stored in the 'kostenstellenbez' key within the 'kostenstellennr' key of the array located at the $key index of $arrKstDB.
