} ?>> I don't think it's *terribly* verbose, as it has good sentence structure to it, but your version is certainly more efficient, hence I've swapped to that. Any other takers? ;) Rich: How about? switch (1) { case $allow_fraction: $filter['flags'] = FILTER_FLAG_ALLOW_FRACTION; break; case $allow_thousand: $filter['flags'] = FILTER_FLAG_ALLOW_THOUSAND; break; case $allow_scientific: $filter['flags'] = FILTER_FLAG_ALLOW_SCIENTIFIC; break; } Would that not work?
