考虑到 PHP 中的日期戳,我如何计算持续时间?我在日期之间使用的日期格式是“Ymd H:i:s”,
我的工作代码只能计算时间之间的持续时间而不考虑日期。
下面是我的代码:
$assigned_time = "2012-05-21 22:02:00";
$completed_time= "2012-05-22 05:02:00";
function hmsDiff ($assigned_time, $completed_time) {
$assigned_seconds = hmsToSeconds($assigned_time);
$completed_seconds = hmsToSeconds($completed_time);
$remaining_seconds = $assigned_seconds - $completed_seconds;
return secondsToHMS($remaining_seconds);
}
function hmsToSeconds ($hms) {
$total_seconds = 0;
list($hours, $minutes, $seconds) = explode(":", $hms);
$total_seconds += $hours * 60 * 60;
$total_seconds += $minutes * 60;
$total_seconds += $seconds;
return $total_seconds;
}
function secondsToHMS ($seconds) {
$minutes = (int)($seconds / 60);
$seconds = $seconds % 60;
$hours = (int)($minutes / 60);
$minutes = $minutes % 60;
return sprintf("%02d", abs($hours)) . ":" .
sprintf("%02d", abs($minutes)) . ":" .
sprintf("%02d", abs($seconds));
}
