How can we know the number of days between two given dates using PHP?

Hi,
The code to find the number of days is:
<?php
function numberofdays($startdate, $enddate) {
$start = strtotime($startdate);
$end = strtotime($enddate);
$difference = $end - $start;
return round($difference / 86400);
}
echo numberofdays("2006-04-05", "2006-04-01");
?>
Thanks
