What is the best approach to compare dates and times in PHP, especially when dealing with database entries?

When comparing dates and times in PHP, especially when dealing with database entries, it is recommended to use the DateTime class. This class provides methods for comparing dates and times accurately, taking into account timezones and daylight saving time. By using the DateTime class, you can ensure that your date and time comparisons are reliable and accurate.

$date1 = new DateTime($date_from_database);
$date2 = new DateTime($current_date);

if ($date1 > $date2) {
    // Date from database is later than current date
} elseif ($date1 < $date2) {
    // Date from database is earlier than current date
} else {
    // Dates are equal
}
