这个函数是有用的，你可以扩展它:

function formatSeconds($seconds) {

if(!is_integer($seconds)) {
    return FALSE;
}

$fmt = "";

$days = floor($seconds / 86400);
if($days) {
    $fmt .= $days."D ";
    $seconds %= 86400;
}

$hours = floor($seconds / 3600);
if($hours) {
    $fmt .= str_pad($hours, 2, '0', STR_PAD_LEFT).":";
    $seconds %= 3600;
}

$mins = floor($seconds / 60 );
if($mins) {
    $fmt .= str_pad($mins, 2, '0', STR_PAD_LEFT).":";
    $seconds %= 60;
}

$fmt .= str_pad($seconds, 2, '0', STR_PAD_LEFT);

return $fmt;}

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

这个函数是有用的，你可以扩展它:

function formatSeconds($seconds) {

if(!is_integer($seconds)) {

    $fmt .= $days."D ";
    $seconds %= 86400;

return $fmt;}

$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;

}

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。

这是一种很好的方法:

function time_converter($sec_time, $format='h:m:s'){
      $hour = intval($sec_time / 3600) >= 10 ? intval($sec_time / 3600) : '0'.intval($sec_time / 3600);
      $minute = intval(($sec_time % 3600) / 60) >= 10 ? intval(($sec_time % 3600) / 60) : '0'.intval(($sec_time % 3600) / 60);
      $sec = intval(($sec_time % 3600) % 60)  >= 10 ? intval(($sec_time % 3600) % 60) : '0'.intval(($sec_time % 3600) % 60);

      $format = str_replace('h', $hour, $format);
      $format = str_replace('m', $minute, $format);
      $format = str_replace('s', $sec, $format);

      return $format;
    }
