How can PHP developers efficiently handle date/time differences in queries without relying on Unix timestamps?

When handling date/time differences in queries without relying on Unix timestamps, PHP developers can use the DateTime class to work with dates and times in a more flexible and readable manner. By creating DateTime objects for the dates involved, developers can easily calculate the differences between them using the diff() method. This approach allows for more precise date/time calculations without the need to convert dates to Unix timestamps.

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

$interval = $date1->diff($date2);
echo $interval->format('%R%a days');
