first page (form.html):

<FORM ACTION="year.php" METHOD="get">
Your age: <INPUT TYPE="text" NAME="age"><BR>
<INPUT TYPE="submit" VALUE="Send it in">
</FORM>

second page (year.php):

<?
$thisyear = date("Y"); // returns 4 digit year;
$bornyear = $thisyear - $age; // $age was defined by passing it from form.html
echo "You were born in " . $bornyear;
?>
