How can DateTime objects be used for date comparisons in PHP instead of Unix Timestamps?

When comparing dates in PHP, using DateTime objects is a more readable and flexible approach compared to Unix Timestamps. DateTime objects allow for easy manipulation and comparison of dates using built-in methods like `diff()` and `compare()`. To compare dates using DateTime objects, simply create two DateTime objects representing the dates you want to compare, and then use the `diff()` method to calculate the difference between them. 

$date1 = new DateTime('2022-01-01');
$date2 = new DateTime('2022-01-15');

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

if($interval->days > 0) {
    echo "Date 2 is after Date 1";
} elseif($interval->days < 0) {
    echo "Date 2 is before Date 1";
} else {
    echo "Date 1 and Date 2 are the same";
}
