Yaay, I'm 45 now :).

Here is another nifty piece of code I found. How does this work? What is 
31556926?

function calculateAge($birthday){
    return floor((time() - strtotime($birthday))/31556926);
}

echo calculateAge('1965-10-17');

--------------------------
$birthday = '1965-08-30';

//calculate years of age (input string: YYYY-MM-DD)

  function birthday ($birthday){
    list($year,$month,$day) = explode("-",$birthday);
    $year_diff  = date("Y") - $year;
    $month_diff = date("m") - $month;
    $day_diff   = date("d") - $day;
#  if ($day_diff < 0 || $month_diff < 0)
    if (($month_diff == 0 && $day_diff < 0) || $month_diff < 0)
      $year_diff--;
    return $year_diff;
  }

echo birthday ($birthday);
