How can timestamps be effectively used in PHP to calculate time differences?

To calculate time differences using timestamps in PHP, you can subtract the timestamps representing the start and end times to get the difference in seconds. You can then convert this difference into minutes, hours, or days as needed using PHP's date and time functions. 

$start_time = strtotime('2022-01-01 12:00:00');
$end_time = strtotime('2022-01-01 14:30:00');

$time_diff_seconds = $end_time - $start_time;

$minutes = floor($time_diff_seconds / 60);
$hours = floor($time_diff_seconds / 3600);
$days = floor($time_diff_seconds / 86400);

echo "Time difference in minutes: $minutes\n";
echo "Time difference in hours: $hours\n";
echo "Time difference in days: $days\n";
