How can PHP be used to calculate the remaining time in minutes based on a given timestamp?

To calculate the remaining time in minutes based on a given timestamp, you can subtract the current timestamp from the given timestamp and convert the result to minutes. This can be achieved by using the time() function to get the current timestamp and then performing the necessary calculations.

$givenTimestamp = strtotime('2022-01-01 12:00:00'); // Example given timestamp
$currentTimestamp = time(); // Get current timestamp

$remainingTimeInSeconds = $givenTimestamp - $currentTimestamp;
$remainingTimeInMinutes = round($remainingTimeInSeconds / 60);

echo "Remaining time in minutes: " . $remainingTimeInMinutes;
