echo $interval->format('%R%a days');
?>

Days Difference Between two dates in PHP

<?php
$daysLeft = 0;
$fromDate = "2019-02-25";
$curDate = date('Y-m-d');
$daysLeft = abs(strtotime($curDate) - strtotime($fromDate));
$days = $daysLeft/(60 * 60 * 24);

printf("Days difference between %s and %s = %d", $fromDate, $curDate, $days);
 ?>
output : Days difference between 2019-02-25 and 2019-03-01 =4
