php - 精确秒到 "day/month/year - minutes : hours : seconds"转换

Question

我正在尝试将秒数转换为日期。这是我目前拥有的(在 php 中):

function secondsToTime($inputSeconds) {
    $secondsInAMinute = 60;
    $secondsInAnHour  = 60 * $secondsInAMinute;
    $secondsInADay    = 24 * $secondsInAnHour;
    $secondsInAMonth = 30 * $secondsInADay;
    $secondsInAYear = 12 * $secondsInAMonth;

    $years = floor($inputSeconds / $secondsInAYear);

    $monthSeconds = $inputSeconds % $secondsInAYear;
    $months = floor($monthSeconds / $secondsInAMonth);

    $daySeconds = $monthSeconds % $secondsInAMonth;
    $days = floor($daySeconds / $secondsInADay);

    $hourSeconds = $daySeconds % $secondsInADay;
    $hours = floor($hourSeconds / $secondsInAnHour);

    $minuteSeconds = $hourSeconds % $secondsInAnHour;
    $minutes = floor($minuteSeconds / $secondsInAMinute);

    $remainingSeconds = $minuteSeconds % $secondsInAMinute;
    $seconds = ceil($remainingSeconds);

    $obj = array(
        'years' => (int) $years,
        'months' => (int) $months,
        'days' => (int) $days,
        'hours' => (int) $hours,
        'minutes' => (int) $minutes,
        'seconds' => (int) $seconds
    );
    return $obj;
}

但这不够准确，因为它没有考虑到月份的不同长度......是否有已知的算法或其他东西可以正确地做到这一点？？

提前致谢

编辑:

对不起，英语不是我的语言......我说我需要转换为日期，但我实际上做的是两个日期之间的差异，我在几秒钟内得到结果，我需要年、月、日、小时、分钟和秒的数量

我想这就是您要找的:

适用于 PHP >= 5.3.0

function secondsToTime($inputSeconds) {
  $then = new DateTime(date('Y-m-d H:i:s', $inputSeconds));
  $now = new DateTime(date('Y-m-d H:i:s', time()));
  $diff = $then->diff($now);
  return array('years' => $diff->y, 'months' => $diff->m, 'days' => $diff->d, 'hours' => $diff->h, 'minutes' => $diff->i, 'seconds' => $diff->s);
}

适用于 PHP >= 5.2.0

function secondsToTime($inputSeconds) {
  $then = new DateTime(date('Y-m-d H:i:s', $inputSeconds));
  $now = new DateTime(date('Y-m-d H:i:s', time()));
  $years_then = $then->format('Y');
  $years_now = $now->format('Y');
  $years = $years_now - $years_then;

  $months_then = $then->format('m');
  $months_now = $now->format('m');
  $months = $months_now - $months_then;

  $days_then = $then->format('d');
  $days_now = $now->format('d');
  $days = $days_now - $days_then;

  $hours_then = $then->format('H');
  $hours_now = $now->format('H');
  $hours = $hours_now - $hours_then;

  $minutes_then = $then->format('i');
  $minutes_now = $now->format('i');
  $minutes = $minutes_now - $minutes_then;

  $seconds_then = $then->format('s');
  $seconds_now = $now->format('s');
  $seconds = $seconds_now - $seconds_then;

  if ($seconds < 0) {
    $minutes -= 1;
    $seconds += 60;
  }
  if ($minutes < 0) {
    $hours -= 1;
    $minutes += 60;
  }
  if ($hours < 0) {
    $days -= 1;
    $hours += 24;
  }
  $months_last = $months_now - 1;
  if ($months_now == 1) {
    $years_now -= 1;
    $months_last = 12;
  }
  // Thank you, second grade. ;)
  if ($months_last == 9 || $months_last == 4 || $months_last == 6 || $months_last == 11) {
    $days_last_month = 30;
  }
  else if ($months_last == 2) {
    if (($years_now % 4) == 0) {
      $days_last_month = 29;
    }
    else {
      $days_last_month = 28;
    }
  }
  else {
    $days_last_month = 31;
  }
  if ($days < 0) {
    $months -= 1;
    $days += $days_last_month;
  }
  if ($months < 0) {
    $years -= 1;
    $months += 12;
  }
  return array('years' => $years, 'months' => $months, 'days' => $days, 'hours' => $hours, 'minutes' => $minutes, 'seconds' => $seconds);
}
