你可以使用gmdate()函数:

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

function timeToSecond($time){
    $time_parts=explode(":",$time);
    $seconds= ($time_parts[0]*86400) + ($time_parts[1]*3600) + ($time_parts[2]*60) + $time_parts[3] ; 
    return $seconds;
}

function secondToTime($time){
    $seconds  = $time % 60;
    $seconds<10 ? "0".$seconds : $seconds;
    if($seconds<10) {
        $seconds="0".$seconds;
    }
    $time     = ($time - $seconds) / 60;
    $minutes  = $time % 60;
    if($minutes<10) {
        $minutes="0".$minutes;
    }
    $time     = ($time - $minutes) / 60;
    $hours    = $time % 24;
    if($hours<10) {
        $hours="0".$hours;
    }
    $days     = ($time - $hours) / 24;
    if($days<10) {
        $days="0".$days;
    }

    $time_arr = array($days,$hours,$minutes,$seconds);
    return implode(":",$time_arr);
}

下面的代码可以准确地显示总小时加上分和秒

$duration_in_seconds = 86401;
if($duration_in_seconds>0)
{
    echo floor($duration_in_seconds/3600).gmdate(":i:s", $duration_in_seconds%3600);
}
else
{
    echo "00:00:00";
}

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

这段代码尽可能地避免了乏味的函数调用和逐条的字符串构建，以及人们为此而创建的大而笨重的函数。

它返回格式为“1h05m00s”的输出，并使用前导零表示分和秒，只要在它们之前有另一个非零时间组件。

它还跳过所有空的前导组件，以避免给你无用的信息，如“0h00m01s”(相反，它将显示为“1s”)。

示例结果：“1s”、“1m00s”、“19m08s”、“1h00m00s”、“4h08m39s”。

$duration = 1; // values 0 and higher are supported!
$converted = [
    'hours' => floor( $duration / 3600 ),
    'minutes' => floor( ( $duration / 60 ) % 60 ),
    'seconds' => ( $duration % 60 )
];
$result = ltrim( sprintf( '%02dh%02dm%02ds', $converted['hours'], $converted['minutes'], $converted['seconds'] ), '0hm' );
if( $result == 's' ) { $result = '0s'; }

如果你想让代码更短(但可读性更差)，你可以避免$转换数组，而是直接将值放在sprintf()调用中，如下所示:

$duration = 1; // values 0 and higher are supported!
$result = ltrim( sprintf( '%02dh%02dm%02ds', floor( $duration / 3600 ), floor( ( $duration / 60 ) % 60 ), ( $duration % 60 ) ), '0hm' );
if( $result == 's' ) { $result = '0s'; }

在上面的两个代码段中，持续时间必须为0或更高。不支持负持续时间。但是你可以使用下面的代码来处理负持续时间:

$duration = -493; // negative values are supported!
$wasNegative = FALSE;
if( $duration < 0 ) { $wasNegative = TRUE; $duration = abs( $duration ); }
$converted = [
    'hours' => floor( $duration / 3600 ),
    'minutes' => floor( ( $duration / 60 ) % 60 ),
    'seconds' => ( $duration % 60 )
];
$result = ltrim( sprintf( '%02dh%02dm%02ds', $converted['hours'], $converted['minutes'], $converted['seconds'] ), '0hm' );
if( $result == 's' ) { $result = '0s'; }
if( $wasNegative ) { $result = "-{$result}"; }
// $result is now "-8m13s"

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)
