Zend Date — day difference

Question

I have the below line of codes

$day1 = new Zend_Date(\'2010-03-01\', \'YYYY-mm-dd\');
$day2 = new Zend_Date(\'2010-03-05\', \'YYYY-mm-dd\');
$dateDiff = $da         


        

Answer 1

number of days between date of registration (later) and date of purchase (before)

// $datePurchase instanceof Zend_Date
// $dateRegistration instanceof Zend_Date
if($datePurchase && $dateRegistration) {
   $diff = $dateRegistration->sub($datePurchase)->toValue();
   $days = ceil($diff/60/60/24)+1;
 }
