Elegant way to get the count of months between two dates?

There are multiple ways to get the count of months between two dates in PHP, but one elegant way is to use the DateTime class and the diff() method. Here is an example of how to use it:

<?php

$date1 = new DateTime("2022-12-01");
$date2 = new DateTime("2023-01-01");
$interval = $date1->diff($date2);
$months = ($interval->y * 12) + $interval->m;

echo $months;

This will output "1" as the difference between December 2022 and January 2023 is one month.
