I have a script I use to calculate the age of users in my database

PHP Code:


			
<?

function calculate_age ($month, $day, $year) {

$ageTime = mktime(0, 0, 0, $month, $day, $year); // Get the person's birthday timestamp

$t = time(); // Store current time for consistency

$age = ($ageTime < 0) ? ( $t + ($ageTime * -1) ) : $t - $ageTime;

$year = 60 * 60 * 24 * 365;

$ageYears = $age / $year;

$actual=floor($ageYears);

return $actual;

}

?>

When I input something like 12-6-1989 it returns an age of 18 which is correct.

But when I was inputing an age of 12-16-1899 it returns an age of 38. Any idea why?
