What are some alternative methods for finding information on date differences in PHP if the search function is not working?

If the search function is not working to find information on date differences in PHP, an alternative method is to manually calculate the date difference using the DateTime class. You can create two DateTime objects with the dates you want to compare and then use the diff() method to get the difference in days, months, or years. 

$date1 = new DateTime('2022-01-01');
$date2 = new DateTime('2022-01-15');
$interval = $date1->diff($date2);
echo $interval->format('%R%a days');
