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呢?

使用DateTime的一个简单方法是:

    $time = 60; //sec.
    $now = time();
    $rep = new DateTime('@'.$now);
    $diff = new DateTime('@'.($now+$time));
    $return = $diff->diff($rep)->format($format);

    //output:  01:04:65

这是一个简单的解决方案,让您能够使用DateTime的格式方法。

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

$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;

}

仅当秒数小于86400(1天)时使用函数gmdate():

$seconds = 8525;
echo gmdate('H:i:s', $seconds);
# 02:22:05

参见: gmdate()

将秒转换为“脚”格式无限制*:

$seconds = 8525;
$H = floor($seconds / 3600);
$i = ($seconds / 60) % 60;
$s = $seconds % 60;
echo sprintf("%02d:%02d:%02d", $H, $i, $s);
# 02:22:05

参见:floor(), sprintf(),算术运算符

DateTime扩展的示例使用:

$seconds = 8525;
$zero    = new DateTime("@0");
$offset  = new DateTime("@$seconds");
$diff    = $zero->diff($offset);
echo sprintf("%02d:%02d:%02d", $diff->days * 24 + $diff->h, $diff->i, $diff->s);
# 02:22:05

参见:DateTime::__construct(), DateTime::modify(), clone, sprintf ()

MySQL示例的结果范围被限制为TIME数据类型,从-838:59:59到838:59:59:

SELECT SEC_TO_TIME(8525);
# 02:22:05

看:SEC_TO_TIME

运行Demo


PostgreSQL的例子:

SELECT TO_CHAR('8525 second'::interval, 'HH24:MI:SS');
# 02:22:05

运行Demo

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

使用DateTime的一个简单方法是:

    $time = 60; //sec.
    $now = time();
    $rep = new DateTime('@'.$now);
    $diff = new DateTime('@'.($now+$time));
    $return = $diff->diff($rep)->format($format);

    //output:  01:04:65
