What alternative methods, such as using DateTime, can be used to calculate time differences in PHP instead of mktime()?

When calculating time differences in PHP, an alternative method to using mktime() is to utilize the DateTime class. DateTime provides a more object-oriented approach to working with dates and times, making it easier to calculate time intervals between two dates. 

// Example using DateTime to calculate time difference
$datetime1 = new DateTime('2022-01-01 12:00:00');
$datetime2 = new DateTime('2022-01-02 12:00:00');
$interval = $datetime1->diff($datetime2);
echo $interval->format('%d days %h hours %i minutes');
