To create a timestamp from a date using the Carbon PHP package, you can use the parse method to create a Carbon instance from the date string, and then use the timestamp method to get the timestamp value. Here's an example:
use Carbon\Carbon;

$dateString = '2022-03-15'; // Example date string
$carbonDate = Carbon::parse($dateString); // Create a Carbon instance from the date string
$timestamp = $carbonDate->timestamp; // Get the timestamp value

echo $timestamp; // Output: 1647331200

In this example, we first define a date string (in the format YYYY-MM-DD) and then use the parse method to create a Carbon instance from the date string. We then use the timestamp method to get the timestamp value, which represents the number of seconds since January 1, 1970, at 00:00:00 UTC. Finally, we output the timestamp value using echo.
