date functions for verifying user input?

[afullcup]

I am collecting a date on a form and want it to be entered as MM/DD/YY - what's the best way to verify in my PHP that it is a correct date?

thanks!

Something i've used:

/**
* We use this to ensure a valid date is entered
*
* @param string Date to be checked.
* @return boolean
*/
function is_valid_date($date)
{
// Expects mm/dd/yyyy
// eg: 08/26/2006
if (preg_match('#[0-9]{2}\/[0-9]{2}\/[0-9]{4}#', $date))
{
$date = explode('/', $date);

// www.php.net/checkdate
if (checkdate($date[0], $date[1], $date[2]))
{
return true;
}
}
return false;
}
