<?php function dateDifference($start_date, $end_date) { // calulating the difference in timestamps $diff = strtotime($start_date) - strtotime($end_date); // 1 day = 24 hours // 24 * 60 * 60 = 86400 seconds return ceil(abs($diff / 86400)); } // start date $start_date = "2016-01-02"; // end date $end_date = "2016-01-21"; // call dateDifference() function to find the number of days between two dates $dateDiff = dateDifference($start_date, $end_date); echo "Difference between two dates: " . $dateDiff . " Days "; ?>
