PHP script to Find Days between two Dates!

Today’s script will be much useful to you and i hope interesting as well. ie., PHP Script to find days between two selected dates.

Let’s see the PHP script (find_days() function):

//this function return two main values status (either true or false) and result (which has all the other details)
function find_days($start_date, $end_date) {

    $response = new stdClass();

    //using try catch in case if any invalid date entered
    try {
        //get the entered start date and end date and convert into datetime
        $sdate = new DateTime($start_date);
        $edate = new DateTime($end_date);

        //here is the real deal, diff() is the function which is going to give us the result
        $dateInterval = $edate->diff($sdate);
        $response->status = true;
        $response->result = $dateInterval;
        return $response;
    } catch (Exception $e) {
        $response->status = false;
        $response->result = 'Invalid Date Format';
        return $response;
    }
}

Read the comments in the script to understand it. You can use it in your existing projects as well.

Basically the above function will receive two parameters “$start_date” and “$end_date” and then converts into DateTime object using DateTime(). And diff() will return the difference between two dates.

Here is the demo script shows you how to use the above function:

<?php

//this function return two main values status (either true or false) and result (which has all the other details)
function find_days($start_date, $end_date) {

    $response = new stdClass();

    //using try catch in case if any invalid date entered
    try {
        //get the entered start date and end date and convert into datetime
        $sdate = new DateTime($start_date);
        $edate = new DateTime($end_date);

        //here is the real deal, diff() is the function which is going to give us the result
        $dateInterval = $edate->diff($sdate);
        $response->status = true;
        $response->result = $dateInterval;
        return $response;
    } catch (Exception $e) {
        $response->status = false;
        $response->result = 'Invalid Date Format';
        return $response;
    }
}
?>

            if (isset($_POST['sdate']) && $_POST['sdate']) {

                $end_date = $_POST['edate'];
                //now call the function
                $days_array = find_days($start_date, $end_date);
                if ($days_array->status) {
                    echo "Result: <b>".$days_array->result->days."</b>  Days";
                } else {
                    echo $days_array->result;
                }
            }
            ?>
        </form>
