一小时是3600秒，一分钟是60秒，为什么不呢?

<?php

$init = 685;
$hours = floor($init / 3600);
$minutes = floor(($init / 60) % 60);
$seconds = $init % 60;

echo "$hours:$minutes:$seconds";

?>

生产:

$ php file.php
0:11:25

(我没有测试这么多，所以地板可能会有错误)

不知道为什么还没有提出这个建议，但是这里有一个使用DateInterval的变体，它的优点是秒> 86400不是问题(只是不要期望小时< 24)

noteable:该函数返回DateInterval对象，因此输出格式由调用者决定

function seconds2interval($seconds) {
    $s = intval($seconds);
    $hrs = floor($s / 3600);
    $min = floor(($s - ($hrs * 3600)) / 60);
    $sec = $s % 60;
    
    $duration = sprintf('PT%dH%dM%dS', $hrs, $min, $sec);
    $d = new DateInterval($duration);
    
    return $d;
}

$d = seconds2interval(93837.3113);  
echo $d->format('%H:%I:%s'); // 26:03:57

试试这个:

date("H:i:s",-57600 + 685);

仅当秒数小于86400(1天)时使用函数gmdate():

$seconds = 8525;
echo gmdate('H:i:s', $seconds);
# 02:22:05

参见： gmdate（）

将秒转换为“脚”格式无限制*:

$seconds = 8525;
$H = floor($seconds / 3600);
$i = ($seconds / 60) % 60;
$s = $seconds % 60;
echo sprintf("%02d:%02d:%02d", $H, $i, $s);
# 02:22:05

参见:floor()， sprintf()，算术运算符

运行Demo

DateTime扩展的示例使用:

$seconds = 8525;
$zero    = new DateTime("@0");
$offset  = new DateTime("@$seconds");
$diff    = $zero->diff($offset);
echo sprintf("%02d:%02d:%02d", $diff->days * 24 + $diff->h, $diff->i, $diff->s);
# 02:22:05

参见:DateTime::__construct()， DateTime::modify()， clone， sprintf ()

运行Demo

MySQL示例的结果范围被限制为TIME数据类型，从-838:59:59到838:59:59:

SELECT SEC_TO_TIME(8525);
# 02:22:05

看:SEC_TO_TIME

运行Demo

PostgreSQL的例子:

SELECT TO_CHAR('8525 second'::interval, 'HH24:MI:SS');
# 02:22:05

运行Demo

写这样的函数返回一个数组

function secondsToTime($seconds) {

  // extract hours
  $hours = floor($seconds / (60 * 60));

  // extract minutes
  $divisor_for_minutes = $seconds % (60 * 60);
  $minutes = floor($divisor_for_minutes / 60);

  // extract the remaining seconds
  $divisor_for_seconds = $divisor_for_minutes % 60;
  $seconds = ceil($divisor_for_seconds);

  // return the final array
  $obj = array(
      "h" => (int) $hours,
      "m" => (int) $minutes,
      "s" => (int) $seconds,
   );

  return $obj;
}

然后像这样简单地调用函数:

secondsToTime(100);

输出是

Array ( [h] => 0 [m] => 1 [s] => 40 )

给你

function format_time($t,$f=':') // t = seconds, f = separator 
{
  return sprintf("%02d%s%02d%s%02d", floor($t/3600), $f, ($t/60)%60, $f, $t%60);
}

echo format_time(685); // 00:11:25
