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

To calculate the number of working days between two dates using the Carbon library in PHP, you can use the diffInWeekdays() method. Here's an example:

First, make sure you have installed the Carbon library via Composer:

composer require nesbot/carbon

Then in your PHP code:

use Carbon\Carbon;

$startDate = Carbon::createFromDate(2022, 1, 1); // Set the start date
$endDate = Carbon::createFromDate(2022, 12, 31); // Set the end date

$workingDays = $startDate->diffInWeekdays($endDate); // Calculate the number of working days

echo "Number of working days: " . $workingDays;

In this example, Carbon::createFromDate() is used to create Carbon instances for the start and end dates. Then, the diffInWeekdays() method is called on the start date, passing the end date as the argument to calculate the difference in working days between the two dates.

Finally, the result is echoed to the output.
