如何在 PHP 中将毫秒数格式化为分钟：秒：毫秒？

How do I format an amount of milliseconds into minutes:seconds:milliseconds in PHP?

提问by designvoid

I have a total ammount of milliseconds (ie 70370) and I want to display it as minutes:seconds:milliseconds ie 00:00:0000.

我有总毫秒数（即 70370），我想将其显示为分钟：秒：毫秒，即 00:00:0000。

How can I do this in PHP?

我怎样才能在 PHP 中做到这一点？

Don't fall into the trap of using date functions for this! What you have here is a time interval, not a date. The naive approach is to do something like this:

不要陷入为此使用日期函数的陷阱！您在这里拥有的是时间间隔，而不是日期。天真的方法是做这样的事情：

date("H:i:s.u", $milliseconds / 1000)

but because the date function is used for (gasp!) dates, it doesn't handle time the way you would want it to in this situation - it takes timezones and daylight savings, etc, into account when formatting a date/time.

但是因为日期函数用于（喘气！）日期，它在这种情况下不会按照您希望的方式处理时间 - 在格式化日期/时间时需要考虑时区和夏令时等。

Instead, you will probably just want to do some simple maths:

相反，您可能只想做一些简单的数学运算：

$input = 70135;

$uSec = $input % 1000;
$input = floor($input / 1000);

$seconds = $input % 60;
$input = floor($input / 60);

$minutes = $input % 60;
$input = floor($input / 60); 

// and so on, for as long as you require.

If you are using PHP 5.3 you can make use of the DateIntervalobject:

如果您使用的是 PHP 5.3，则可以使用该DateInterval对象：

list($seconds, $millis) = explode('.', $milliseconds / 1000);
$range = new DateInterval("PT{$seconds}S");
echo $range->format('%H:%I:%S') . ':' . str_pad($millis, 3, '0', STR_PAD_LEFT);

why bother with date()and formatting when you can just use math ? if $msis your number of milliseconds

date()当您可以只使用数学时，为什么还要麻烦和格式化？如果$ms是你的毫秒数

echo floor($ms/60000).':'.floor(($ms%60000)/1000).':'.str_pad(floor($ms%1000),3,'0', STR_PAD_LEFT);

Try this function to display amount of milliseconds the way you like:

试试这个函数以你喜欢的方式显示毫秒数：

<?php
function udate($format, $utimestamp = null)
{
   if (is_null($utimestamp)) {
       $utimestamp = microtime(true);
   }

   $timestamp = floor($utimestamp);
   $milliseconds = round(($utimestamp - $timestamp) * 1000000);

   return date(preg_replace('`(?<!\\)u`', sprintf("%06u", $milliseconds), $format), $timestamp);
}

echo udate('H:i:s.u'); // 19:40:56.78128
echo udate('H:i:s.u', 654532123.04546); // 16:28:43.045460
?>

I believe there's no built-in function for formatting miliseconds in PHP, you'll need to use maths.

我相信 PHP 中没有用于格式化毫秒的内置函数，您需要使用数学。

As mentioned in the manual:

正如手册中提到的：

u Microseconds (added in PHP 5.2.2) Example: 654321

u 微秒（PHP 5.2.2 中新增） 示例：654321

We have a 'u' parameter for the date() function

我们有一个用于 date() 函数的 'u' 参数

Example:

例子：

if(($u/60) >= 60)
{
$u = mktime(0,($u / 360));
}
date('H:i:s',$u);

convert milliseconds to formatted time

将毫秒转换为格式化时间

<?php
/* Write your PHP code here */
$input = 7013512333;

$uSec = $input % 1000;
$input = floor($input / 1000);

$seconds = $input % 60;
$input = floor($input / 60);

$minutes = $input % 60;
$input = floor($input / 60);

$hour = $input ;

echo sprintf('%02d %02d %02d %03d', $hour, $minutes, $seconds, $uSec);
?>
