How to calculate the number of months between two dates using Carbon in PHP?

To calculate the number of months between two dates using Carbon in PHP, you can use the diffInMonths() method. Here is an example:

use Carbon\Carbon;

$startDate = Carbon::parse('2021-01-01');
$endDate = Carbon::parse('2021-12-31');

$months = $startDate->diffInMonths($endDate);

echo $months; // Output: 11

In the above example, we create two Carbon instances representing the start and end dates. Then, we use the diffInMonths() method to calculate the number of months between these two dates. Finally, we display the result in the output.
