How can logical operators like != be used to improve date comparison in PHP?

When comparing dates in PHP, logical operators like != can be used to easily check if two dates are not equal. This can be useful when comparing dates from different sources or when checking if a certain date is not equal to today's date. By using logical operators, you can streamline the date comparison process and make the code more readable. 

$date1 = '2021-10-15';
$date2 = '2021-10-16';

if ($date1 != $date2) {
    echo 'The dates are not equal.';
} else {
    echo 'The dates are equal.';
}
