How can PHP code be optimized for efficiency when calculating date differences?

When calculating date differences in PHP, it's important to optimize the code for efficiency to avoid unnecessary processing time. One way to do this is by using built-in PHP functions like `DateTime` to perform the date calculations. By utilizing these functions, you can streamline the code and improve its performance. 

$startDate = new DateTime('2022-01-01');
$endDate = new DateTime('2022-12-31');

$interval = $startDate->diff($endDate);
$daysDifference = $interval->days;

echo "The difference in days between the two dates is: " . $daysDifference;
