In what situations should the date_diff function be used in PHP programming, and what are the common pitfalls to watch out for when using it?

The date_diff function in PHP should be used when you need to calculate the difference between two dates. This can be useful for tasks such as calculating the age of a person, finding the duration between two events, or determining the time elapsed since a specific date. One common pitfall to watch out for when using date_diff is ensuring that the dates are in the correct format and that the function is used correctly. Additionally, be aware of the limitations of the function, such as not being able to calculate differences in years accurately if the dates are not exactly one year apart. 

$date1 = new DateTime('2022-01-01');
$date2 = new DateTime('2022-03-15');

$interval = date_diff($date1, $date2);

echo $interval->format('%R%a days');
