Are there any built-in PHP functions or classes that can simplify the calculation of time differences between DateTime values?

Calculating time differences between DateTime values in PHP can be simplified by using the DateTime and DateInterval classes. By subtracting one DateTime object from another, you can obtain a DateInterval object representing the difference in time. This object can then be formatted or used to extract specific values like days, hours, minutes, and seconds. 

$datetime1 = new DateTime('2022-01-01 12:00:00');
$datetime2 = new DateTime('2022-01-02 14:30:00');

$interval = $datetime1->diff($datetime2);

echo $interval->format('%d days, %h hours, %i minutes, %s seconds');
