What are the best practices for handling date comparisons in PHP to avoid issues with transitioning between months?

When comparing dates in PHP, it's important to consider the varying number of days in each month. To avoid issues with transitioning between months, it's best to use PHP's built-in DateTime class along with the diff() method to accurately calculate the difference between two dates. 

$date1 = new DateTime('2022-01-31');
$date2 = new DateTime('2022-02-01');

$interval = $date1->diff($date2);

if($interval->format('%R%a') > 0) {
    echo "Date 2 is after Date 1";
} elseif($interval->format('%R%a') < 0) {
    echo "Date 2 is before Date 1";
} else {
    echo "Dates are the same";
}
