Help WIth DOB

[refiking]

On the prior form, I collected the month, date and year.  How can I make it appear as mm-dd-yyyy?  Here is the code:

<?php
session_start();
print $name;
$day = $_POST['day'];
$month = $_POST['month'];
$year = $_POST['year'];
$dob = $month $day, $year;
$_SESSION['dob'] = $dob;
print $_SESSION['dob'];

$dob = sprintf('%02d-%02d-%d', $month, $day, $year);

If you're storing this in a database, please use a DATETIME field.

... or a DATE field if the time is irrelevant
