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);
}

其他解决方案使用gmdate，但在超过86400秒的边缘情况下会失败。为了解决这个问题，我们可以自己简单地计算小时数，然后让gmdate将剩余的秒计算为分/秒。

echo floor($seconds / 3600) . gmdate(":i:s", $seconds % 3600);

输入:6030 输出:1:40:30

输入:2000006030 输出:555557:13:50

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 )

我已经在这里解释过了 把答案也粘贴到这里

在23:59:59小时之前，您可以使用PHP默认函数

echo gmdate("H:i:s", 86399);

只会返回结果直到23:59:59

如果你的秒数大于86399 在@VolkerK的帮助下回答

$time = round($seconds);
echo sprintf('%02d:%02d:%02d', ($time/3600),($time/60%60), $time%60);

将是使用…的最佳选择。

$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;

}
