php将秒转换为小时：分钟：秒

我需要将秒转换为“小时：分钟：秒”。

例如：“685”转换为“00:11:25”

我怎样才能做到这一点？

第一种方法：

你可以使用这个gmdate()功能：

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

第二种方法：format_time

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

第三种方法：自定义函数

   /** 
     * Convert number of seconds into hours, minutes and seconds 
     * and return an array containing those values 
     * 
     * @param integer $inputSeconds Number of seconds to parse 
     * @return array 
     */ 

    function secondsToTime($inputSeconds) {

        $secondsInAMinute = 60;
        $secondsInAnHour  = 60 * $secondsInAMinute;
        $secondsInADay    = 24 * $secondsInAnHour;

        // extract days
        $days = floor($inputSeconds / $secondsInADay);

        // extract hours
        $hourSeconds = $inputSeconds % $secondsInADay;
        $hours = floor($hourSeconds / $secondsInAnHour);

        // extract minutes
        $minuteSeconds = $hourSeconds % $secondsInAnHour;
        $minutes = floor($minuteSeconds / $secondsInAMinute);

        // extract the remaining seconds
        $remainingSeconds = $minuteSeconds % $secondsInAMinute;
        $seconds = ceil($remainingSeconds);

        // return the final array
        $obj = array(
            \'d\' => (int) $days,
            \'h\' => (int) $hours,
            \'m\' => (int) $minutes,
            \'s\' => (int) $seconds,
        );
        return $obj;
    }
