note 32979 added to function.date

Wrote a function to figure out age. Watch out though, it doesn't (AFAIK) compute leapyears. function age( $birthyear, $birthmonth, $birthday) { // This function does not take into account leapyears - aie! $todayyear = date("Y"); $todaymonth = date("m"); $todayday = date("d"); // First subtract days $ageday = $todayday - $birthday; $agemonth = $todaymonth - $birthmonth; $ageyear = $todayyear - $birthyear; // Of course, these values could come out negative, and that would // be a bad thing. So we will use php's broken time features // to normalize the date this // We do this by adding our time to 1970. Of course, PHP's date // is broken, so we'll add only the remainder of 50 years $fifties = floor($ageyear/50); $fiftymod = $ageyear % 50; $agesince1970 = mktime(0,0,0, $agemonth, $ageday, $fiftymod+1970); return $fifties * 50 + (date("Y", $agesince1970)-1970); } ---- Manual Page -- http://www.php.net/manual/en/function.date.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+32979 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+32979&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+32979&report=yes
