Are there any specific PHP functions or methods that can help accurately calculate date differences?

When calculating date differences in PHP, you can use the `DateTime` class along with its methods to accurately compute the duration between two dates. The `diff()` method can be used to calculate the difference between two `DateTime` objects, providing a `DateInterval` object that represents the time span. 

$date1 = new DateTime('2022-01-01');
$date2 = new DateTime('2022-01-10');

$interval = $date1->diff($date2);
echo $interval->format('%R%a days');
