What are some best practices for converting date differences into days in PHP?

When converting date differences into days in PHP, it is important to use the DateTime class to accurately calculate the difference between two dates. This class provides a simple and reliable way to perform date calculations and conversions. By using the diff() method of the DateTime class, we can easily calculate the difference between two dates in days. 

$startDate = new DateTime('2022-01-01');
$endDate = new DateTime('2022-01-10');
$interval = $startDate->diff($endDate);
$daysDifference = $interval->days;

echo $daysDifference; // Output: 9
