note 17428 added to function.mktime

You can calculate age using the code below. This code accounts for the UNIX Epoch and leap years. All you need to do is provide it a date in the m/d/yyyy format. <?php $birthday = "7/4/1960"; //must be as m/d/yyyy $bday = explode("/", $birthday); //parse $b_mm = $bday[0]; //birthday month $b_dd = $bday[1]; //birthday day $b_yyyy = $bday[2]; //birthday year //compare timestamps of mm/dd for birthday and today $bday_mm_dd = mktime(0,0,0,$b_mm,$b_dd,0); $today_mm_dd = mktime(0,0,0,date("m"),date("d"),0); $age = date("Y", time()) - $b_yyyy; if ($bday_mm_dd > $today_mm_dd) { //birthday hasn't arrived yet, so subtract a year $age = $age - 1; } print $age; //age equals 41 (on date of this note) ?> Of course this code assumes the client and server machines exist in the same day. -DON -- http://www.php.net/manual/en/function.mktime.php http://master.php.net/manage/user-notes.php?action=edit+17428 http://master.php.net/manage/user-notes.php?action=delete+17428 http://master.php.net/manage/user-notes.php?action=reject+17428
