What are the advantages of using DateTime functions in PHP compared to manual date calculations?

When working with dates and times in PHP, using DateTime functions provides several advantages over manual date calculations. DateTime functions handle timezones, daylight saving time, leap years, and other complexities automatically, making it easier to work with dates accurately. Additionally, DateTime functions offer a wide range of formatting options and methods for modifying dates, simplifying date manipulation tasks. 

// Example of using DateTime functions to calculate the difference between two dates

$date1 = new DateTime('2022-01-01');
$date2 = new DateTime('2022-02-01');
$interval = $date1->diff($date2);
echo $interval->format('%R%a days');
