How to add days to a date using Carbon in PHP?

To add days to a date using Carbon in PHP, follow these steps:

1. Install Carbon if you haven't already. You can do this using Composer by running the following command in your terminal:

   composer require nesbot/carbon

2. Import the Carbon class at the beginning of your PHP file:

   use Carbon\Carbon;

3. Create an instance of the Carbon class and parse the initial date. You can pass the initial date as a string or use a predefined format:

   $date = Carbon::parse('2022-10-15'); // or $date = Carbon::createFromFormat('Y-m-d', '2022-10-15');

4. Use the addDays() method to add the desired number of days to the date. This method modifies the instance itself and returns a new instance of Carbon:

   $newDate = $date->addDays(7); // adds 7 days to the date and returns a new Carbon instance

5. Format and display the new date using the format() method, if needed:

   echo $newDate->format('Y-m-d'); // prints the new date in the specified format

That's it! You have successfully added days to a date using Carbon in PHP.
