    2、编写代码：

    <?php

require 'vendor/autoload.php';

use Carbon\Carbon;

$year = 2023;
$month = 2;

// Get the first day of the month.
$firstDayOfMonth = Carbon::create($year, $month, 1)->startOfMonth();

echo 'First day of the month: ' . $firstDayOfMonth->format('Y-m-d') . PHP_EOL;

// Get the last day of the month.
$lastDayOfMonth = Carbon::create($year, $month, 1)->endOfMonth();

// Print the first day and last day of the month.
echo 'Last day of the month: ' . $lastDayOfMonth->format('Y-m-d') . PHP_EOL;

?>
