RE: [PHP] checkdate function

I think you're stuck with the extra validation step, but you can do it quite neatly with a replacement function that looks something like this: function myCheckdate ($m, $d, $y, $min = 1900, $max = 2100) { // check whether $y is within allowable range if ($y <= $min || $y >= $max) return false; // the year is OK: checkdate can do its stuff return (checkdate($m, $d, $y)) } You can adjust the default allowable years to match what you usually need, and then override them as necessary. Personally I'd like to see PHP's checkdate() work a bit like the one above, or maybe have checkReasonableDate() and checkImprobableDate(): I'm prepared to believe that some PHP developers need to validate three- and five- digit years, but I can't believe that it's *that* common :-) Cheers Jon -- Need a web or desktop developer in the London area?
