Calculate days difference in PHP

To calculate the number of days between two dates in PHP, you can use the DateTime class and the diff() method, which returns a DateInterval object representing the difference between two dates. Here’s an example:

$date1 = new DateTime('2022-02-22');
$date2 = new DateTime('2023-02-22');

$interval = $date1->diff($date2);
$days = $interval->days;
echo "The number of days between the two dates is: $days";

In this example, we create two DateTime objects, $date1 and $date2, using the new keyword. We then use the diff() method to calculate the difference between the two dates, which returns a DateInterval object. We can access the number of days in the interval using the days property of the DateInterval object, and store it in a variable $days. Finally, we print the number of days using the echo statement.

This example assumes that the two dates are in the “YYYY-MM-DD” format. If your dates are in a different format, you can use the createFromFormat() method of the DateTime class to create the DateTime objects with the correct format.

here’s another way to calculate the number of days between two dates in PHP using the strtotime() function:

$date1 = '2022-02-22';
$date2 = '2023-02-22';

$diff = strtotime($date2) - strtotime($date1);
$days = floor($diff / (60 * 60 * 24));
echo "The number of days between the two dates is: $days";

In this example, we use the strtotime() function to convert the date strings to Unix timestamps, and…
