What potential logic errors should be considered when validating date ranges in PHP?

When validating date ranges in PHP, potential logic errors to consider include ensuring that the start date is before the end date, handling edge cases such as leap years or different month lengths, and considering time zones if applicable. To address these issues, you can use PHP's built-in DateTime class to compare and manipulate dates accurately. 

$start_date = new DateTime('2022-01-01');
$end_date = new DateTime('2022-01-31');

if ($start_date < $end_date) {
    echo "Valid date range";
} else {
    echo "Invalid date range";
}
