We can get the days between two dates by below code.
<?php $today= date('d-m-Y'); // get today's date // here you can also change today's date according to your requirement $timestamp= date('Y-m-d',strtotime($fetch['timestamp'])); // here timestamp value has been retrieved from database $datetime1 = new DateTime("$timestamp"); $datetime2 = new DateTime("$today"); $difference = $datetime1->diff($datetime2); // compare both dates $days= 'Difference: '.$difference->days.' days'; // get the days difference in a variable echo $days; // Print the days where you want to show // You can also get the difference in year, months // to get the year difference, use below code $years= 'Difference: '.$difference->y.' years'; echo $years; // to get the month difference, use below code $months= 'Difference: '.$difference->m.' months'; echo $months; ?>
