$datetime1 = new DateTime('2009-10-11');
$datetime2 = new DateTime('2009-10-13');
$interval = $datetime1->diff($datetime2);
echo $interval->format('%R%a days');

$datetime1 = date_create('2009-10-11');
$datetime2 = date_create('2009-10-13');
$interval = date_diff($datetime1, $datetime2);
echo $interval->format('%R%a days');

function DateDiff($strDate1,$strDate2)
{
return (strtotime($strDate2) - strtotime($strDate1))/ ( 60 * 60 * 24 ); // 1 day = 60*60*24
