在java中你可以使用这种方法。

   private String getHmaa(long seconds) {
    String string;
    int hours = (int) seconds / 3600;
    int remainder = (int) seconds - hours * 3600;
    int mins = remainder / 60;
    //remainder = remainder - mins * 60;
    //int secs = remainder;

    if (hours < 12 && hours > 0) {
        if (mins < 10) {
            string = String.valueOf((hours < 10 ? "0" + hours : hours) + ":" + (mins > 0 ? "0" + mins : "0") + " AM");
        } else {
            string = String.valueOf((hours < 10 ? "0" + hours : hours) + ":" + (mins > 0 ? mins : "0") + " AM");
        }
    } else if (hours >= 12) {
        if (mins < 10) {
            string = String.valueOf(((hours - 12) < 10 ? "0" + (hours - 12) : ((hours - 12) == 12 ? "0" : (hours - 12))) + ":" + (mins > 0 ? "0" + mins : "0") + ((hours - 12) == 12 ? " AM" : " PM"));
        } else {
            string = String.valueOf(((hours - 12) < 10 ? "0" + (hours - 12) : ((hours - 12) == 12 ? "0" : (hours - 12))) + ":" + (mins > 0 ? mins : "0") + ((hours - 12) == 12 ? " AM" : " PM"));
        }
    } else {
        if (mins < 10) {
            string = String.valueOf("0" + ":" + (mins > 0 ? "0" + mins : "0") + " AM");
        } else {
            string = String.valueOf("0" + ":" + (mins > 0 ? mins : "0") + " AM");
        }
    }
    return string;
}

任何人在未来寻找这个，这给了最初的海报要求的格式。

$init = 685;
$hours = floor($init / 3600);
$hrlength=strlen($hours);
if ($hrlength==1) {$hrs="0".$hours;}
else {$hrs=$hours;} 

$minutes = floor(($init / 60) % 60);
$minlength=strlen($minutes);
if ($minlength==1) {$mins="0".$minutes;}
else {$mins=$minutes;} 

$seconds = $init % 60;
$seclength=strlen($seconds);
if ($seclength==1) {$secs="0".$seconds;}
else {$secs=$seconds;} 

echo "$hrs:$mins:$secs";

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

在java中你可以使用这种方法。

   private String getHmaa(long seconds) {
    String string;
    int hours = (int) seconds / 3600;
    int remainder = (int) seconds - hours * 3600;
    int mins = remainder / 60;
    //remainder = remainder - mins * 60;
    //int secs = remainder;

    if (hours < 12 && hours > 0) {
        if (mins < 10) {
            string = String.valueOf((hours < 10 ? "0" + hours : hours) + ":" + (mins > 0 ? "0" + mins : "0") + " AM");
        } else {
            string = String.valueOf((hours < 10 ? "0" + hours : hours) + ":" + (mins > 0 ? mins : "0") + " AM");
        }
    } else if (hours >= 12) {
        if (mins < 10) {
            string = String.valueOf(((hours - 12) < 10 ? "0" + (hours - 12) : ((hours - 12) == 12 ? "0" : (hours - 12))) + ":" + (mins > 0 ? "0" + mins : "0") + ((hours - 12) == 12 ? " AM" : " PM"));
        } else {
            string = String.valueOf(((hours - 12) < 10 ? "0" + (hours - 12) : ((hours - 12) == 12 ? "0" : (hours - 12))) + ":" + (mins > 0 ? mins : "0") + ((hours - 12) == 12 ? " AM" : " PM"));
        }
    } else {
        if (mins < 10) {
            string = String.valueOf("0" + ":" + (mins > 0 ? "0" + mins : "0") + " AM");
        } else {
            string = String.valueOf("0" + ":" + (mins > 0 ? mins : "0") + " AM");
        }
    }
    return string;
}

你可以使用gmdate()函数:

echo gmdate("H:i:s", 685);

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)
