你可以使用gmdate()函数:

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

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

$given = 685;

 /*
 * In case $given == 86400, gmdate( "H" ) will convert it into '00' i.e. midnight.
 * We would need to take this into consideration, and so we will first
 * check the ratio of the seconds i.e. $given:$number_of_sec_in_a_day
 * and then after multiplying it by the number of hours in a day (24), we
 * will just use "floor" to get the number of hours as the rest would
 * be the minutes and seconds anyways.
 *
 * We can also have minutes and seconds combined in one variable,
 * e.g. $min_sec = gmdate( "i:s", $given );
 * But for versatility sake, I have taken them separately.
 */

$hours = ( $given > 86399 ) ? '0'.floor( ( $given / 86400 ) * 24 )-gmdate( "H", $given ) : gmdate("H", $given );

$min = gmdate( "i", $given );

$sec = gmdate( "s", $given );

echo $formatted_string = $hours.':'.$min.':'.$sec;

将其转换为函数:

function getHoursFormat( $given ){

 $hours = ( $given > 86399 ) ? '0'.floor( ( $given / 86400 ) * 24 )-gmdate( "H", $given ) : gmdate("H", $given );

 $min = gmdate( "i", $given );

 $sec = gmdate( "s", $given );

 $formatted_string = $hours.':'.$min.':'.$sec;

 return $formatted_string;

}

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（）

运行Demo

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

<?php
$time=3*3600 + 30*60;


$year=floor($time/(365*24*60*60));
$time-=$year*(365*24*60*60);

$month=floor($time/(30*24*60*60));
$time-=$month*(30*24*60*60);

$day=floor($time/(24*60*60));
$time-=$day*(24*60*60);

$hour=floor($time/(60*60));
$time-=$hour*(60*60);

$minute=floor($time/(60));
$time-=$minute*(60);

$second=floor($time);
$time-=$second;
if($year>0){
    echo $year." year, ";
}
if($month>0){
    echo $month." month, ";
}
if($day>0){
    echo $day." day, ";
}
if($hour>0){
    echo $hour." hour, ";
}
if($minute>0){
    echo $minute." minute, ";
}
if($second>0){
    echo $second." second, ";
}

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
