本文翻译自：Convert seconds to Hour:Minute:Second
I need to convert seconds to "Hour:Minute:Second". 我需要将秒转换为“小时：分钟：秒”。
For example: "685" converted to "00:11:25" 例如：“685”转换为“00:11:25”
How can I achieve this? 我怎样才能做到这一点？

Just in case anyone else is looking for a simple function to return this nicely formatted (I know it is not the format the OP asked for), this is what I've just come up with. 以防万一其他人正在寻找一个简单的函数来返回这个格式很好的（我知道它不是OP要求的格式），这就是我刚刚提出的。 Thanks to @mughal for the code this was based on. 感谢@mughal的代码，这是基于。
function format_timer_result($time_in_seconds){ $time_in_seconds = ceil($time_in_seconds); // Check for 0 if ($time_in_seconds == 0){ return 'Less than a second'; } // Days $days = floor($time_in_seconds / (60 * 60 * 24)); $time_in_seconds -= $days * (60 * 60 * 24); // Hours $hours = floor($time_in_seconds / (60 * 60)); $time_in_seconds -= $hours * (60 * 60); // Minutes $minutes = floor($time_in_seconds / 60); $time_in_seconds -= $minutes * 60; // Seconds $seconds = floor($time_in_seconds); // Format for return $return = ''; if ($days > 0){ $return .= $days . ' day' . ($days == 1 ? '' : 's'). ' '; } if ($hours > 0){ $return .= $hours . ' hour' . ($hours == 1 ? '' : 's') . ' '; } if ($minutes > 0){ $return .= $minutes . ' minute' . ($minutes == 1 ? '' : 's') . ' '; } if ($seconds > 0){ $return .= $seconds . ' second' . ($seconds == 1 ? '' : 's') . ' '; } $return = trim($return); return $return; }Anyone whose looking for this in the future, this gives the format the initial poster asked for. 任何人在将来寻找这个，这给出了初始海报要求的格式。
$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";Use function gmdate() only if seconds are less than 86400 (1 day) : 仅当秒小于86400 （1天）时才使用函数gmdate() ） ：
$seconds = 8525; echo gmdate('H:i:s', $seconds); # 02:22:05See: gmdate() 请参阅： gmdate（）

The gmtdate() function didn't work for me as I was tracking hours worked on a project and if it's over 24 hours, you get amount left over after 24 hours is subtracted. gmtdate（）函数对我来说不起作用，因为我正在跟踪项目的工作时间，如果超过24小时，则会减去24小时后剩余的金额。 In other words 37 hours becomes 13 hours. 换句话说，37小时变为13小时。 (all as stated above by Glavic - thanks for your examples!) This one worked well: （如上所述，Glavic - 感谢你的例子！）这个很好用：
Convert seconds to format by 'foot' no limit : $seconds = 8525; $H = floor($seconds / 3600); $i = ($seconds / 60) % 60; $s = $seconds % 60; echo sprintf("%02d:%02d:%02d", $H, $i, $s); # 02:22:05
