One can also take another tack and use a series of statements like

next if not proper_year($year); next if not proper_month($month_nr); next if not proper_day($day_in_month, $month_nr, $year);

which might be said to offer the best of both concision (it's self-documenting, or can be made so) and encapsulation (annual, monthly and daily proprieties defined in one place in their respective validation functions). This sort of approach is what I usually prefer if I have the opportunity to take a second pass at a program and consolidate.

Then there's the OO approach...

    Yes, you are right, this is probably better. As I said earlier, my example was not given as a proper way to validate dates, but only as an example of rules that are self-documenting or obvious to anyone and thus don't really need any comments
