To calculate the difference in minutes between two timestamps using Carbon in PHP, you can use the diffInMinutes() method. Here's an example:
use Carbon\Carbon;
$timestamp1 = Carbon::parse('2022-12-31 10:00:00');
$timestamp2 = Carbon::parse('2022-12-31 10:30:00');
$diffInMinutes = $timestamp1->diffInMinutes($timestamp2);
echo $diffInMinutes;
In this example, we have two timestamps, $timestamp1 and $timestamp2. We use the diffInMinutes() method on $timestamp1 and pass $timestamp2 as its argument to calculate the difference in minutes between them.
The result will be the number of minutes between the two timestamps (in this case, it will be 30 minutes).
