将秒转换为更具体格式的便捷方法

Question

有没有什么方便的方法可以将秒转换成更具体的格式。

例如：

我想改信

559 seconds

至

9 min 19 sec

Answer 1

可以使用

echo gmdate("H:i:s", 559 );

Answer 2

$seconds = 559;

$minutes = floor($seconds / 60);  // 9
$seconds = $seconds % 60;         // 19

Answer 3

请参阅http://dev.kafol.net/2008/09/php-calculating-time-span-duration.html

 $days = floor($seconds/60/60/24);
 $hours = $seconds/60/60%24;
 $mins = $seconds/60%60;
 $secs = $seconds%60;

 $duration='';
 if($days>0) $duration .= "$days days ";
 if($hours>0) $duration .= "$hours hours ";
 if($mins>0) $duration .= "$mins minutes ";
 if($secs>0) $duration .= "$secs seconds ";
