Calculate the number of days between two dates in PHP

 

<?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 ";
