php - 还剩几秒？

Question

我试图格式化一个日期来表示还剩多少时间（以可读的格式）：

<?php
    $seconds = 23414;
    $date = new DateTime();
    $date->setTime(0, 0, $seconds);
    echo $date->format('z G:i:s');
?>

这个例子可能输出类似：344 11:46:45不是我想要的。它应该显示类似于 6 days, 4:12:36 的内容。我只是在这里没有看到任何内容： http://www.php.net/ Manual/en/function.date.php 这将帮助我正确格式化它。有想法吗？

我不知道任何内置的东西，但它很容易编写：

function formatSeconds($secondsLeft) {

  $minuteInSeconds = 60;
  $hourInSeconds = $minuteInSeconds * 60;
  $dayInSeconds = $hourInSeconds * 24;

  $days = floor($secondsLeft / $dayInSeconds);
  $secondsLeft = $secondsLeft % $dayInSeconds;

  $hours = floor($secondsLeft / $hourInSeconds);
  $secondsLeft = $secondsLeft % $hourInSeconds;

  $minutes= floor($secondsLeft / $minuteInSeconds);

  $seconds = $secondsLeft % $minuteInSeconds;

  $timeComponents = array();

  if ($days > 0) {
    $timeComponents[] = $days . " day" . ($days > 1 ? "s" : "");
  }

  if ($hours > 0) {
    $timeComponents[] = $hours . " hour" . ($hours > 1 ? "s" : "");
  }

  if ($minutes > 0) {
    $timeComponents[] = $minutes . " minute" . ($minutes > 1 ? "s" : "");
  }

  if ($seconds > 0) {
    $timeComponents[] = $seconds . " second" . ($seconds > 1 ? "s" : "");
  }

  if (count($timeComponents) > 0) {
    $formattedTimeRemaining = implode(", ", $timeComponents);
    $formattedTimeRemaining = trim($formattedTimeRemaining);
  } else {
    $formattedTimeRemaining = "No time remaining.";
  }

  return $formattedTimeRemaining;

}

我还没有彻底测试它，但我运行的测试运行良好。在使用它之前，您可能想自己测试一下。

类似于：

$SECONDS_IN_MINUTE = 60;
$SECONDS_IN_HOUR = $SECONDS_IN_MINUTE * 60;
$SECONDS_IN_DAY = $SECONDS_IN_HOUR * 24;

$days = 0;
$hours = 0;
$minutes = 0;
$seconds = 23414;

while ($seconds > $SECONDS_IN_DAY) {
   $days++;
   $seconds -= $SECONDS_IN_DAY;
}
while ($seconds > $SECONDS_IN_HOUR) {
   $hours++;
   $seconds -= $SECONDS_IN_HOUR;
}
while ($seconds > $SECONDS_IN_MINUTE) {
   $minutes++;
   $seconds -= $SECONDS_IN_MINUTE;
}

echo ($days > 0 ? $days . ' day' . ($days > 1 ? 's' : '') . ', ' : '') . 
     $hours . ':' . str_pad($minutes, 2, '0',  STR_PAD_LEFT) . ':' . str_pad($seconds, 2, '0',  STR_PAD_LEFT);

很脏，但应该可以用。
