What are the advantages of using the DateTime class in PHP for date and time calculations compared to traditional date functions?

When working with date and time calculations in PHP, using the DateTime class provides a more object-oriented approach compared to traditional date functions like strtotime() or date(). The DateTime class offers a more intuitive and flexible way to manipulate dates, as well as built-in methods for common operations such as adding or subtracting time intervals. Additionally, the DateTime class handles timezones more effectively, making it easier to work with dates in different time zones. 

// Using DateTime class for date and time calculations
$startDate = new DateTime('2022-01-01');
$endDate = new DateTime('2022-12-31');
$interval = $startDate->diff($endDate);
echo $interval->format('%a days');
