problem with this age validator - workarounds?

[Julia Briggs]

Hello, I am trying to find a workaround for the Unix date issue to
calculate ages based on a persons birthdate and the current date. Here
is the code I am working with now,

<?php

$dob = "10 July 1981";
$dob = strtotime($dob);

$today1 = strtotime ('now');
$today=date("d.m.Y",$today1);
$f_date1 = $person_dob;
$f_date=date("d.m.Y",$f_date1);

$difference = intval(((($f_date1 - $today1)/86400+1)*-1)/365);

print $difference;

?>

This obvisouly will work, until I start inputting birthdates pre-1970.
Is there something better (that is accurate) which will calculate &
accept the long birthdate format I am using here?

I noticed that Message-ID:
<11**********************@z14g2000cwz.googlegroups .com> from Julia
Briggs contained the following:

Not tested.

$dob = "21 Feb 1965";
$dob = strtotime($dob);
$difference = intval(abs($dob-time())/31536000);
echo $difference ."\n";
