是否有等同于 C#.NET DateTime.Now.ToString("yyyyMMddHHmmssfff") 的 PHP7?

问题描述

考虑这个 C#.NET 代码:

Considering this C#.NET code:

DateTime.Now.ToString("yyyyMMddHHmmssfff")

，PHP 中是否有等价物?

, is there any equivalent in PHP?

目前，我使用以下内容:

For the moment, I use the following:

$date = new DateTime();
$timestamp = $date->getTimestamp();
$formatted_timestamp = gmdate("YmdHms", $timestamp) . round(microtime(true) * 1000);

但是，它不会输出相同的结果(从秒开始).

However, it doesn't output the same results (from the seconds).

推荐答案

由于您已经在使用 DateTime 对象，您可以简单地对其进行格式化:

Since you're already using a DateTime object, you could simply format it:

$date = new DateTime();
return $date->format('YmdHisv');

'v' 就是您要查找的内容(毫秒).

the 'v' is what you're looking for (milliseconds).

注意:这需要 PHP 7.1，如果您在不带参数的情况下实例化 DateTime()，以获得一些非 0 毫秒(或微)秒.

Caution: this requires PHP 7.1, if you instantiate DateTime() with no arg, in order to obtain some non-0 milli (or micro) seconds.
