我想得到的是<代码>时间(),但应当准确无误:
2010-11-15 21:21:00:987
是否在PHP中这样做?

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` , $milliseconds, $format), $timestamp);
}
echo udate( Y-m-d H:i:s:u ); // 2010-11-15 21:21:00:987
http://de.php.net/microtime"rel=“noreferer”>microtime,将其改为milliseconds:
$millitime = round(microtime(true) * 1000);
使用<代码>microtime()功能。
见手册网页:。
[EDIT] 根据要求获得年度/月/日/日/小时/分钟/秒/秒/秒的产出:
类似情况:
list($usec, $sec) = explode(" ", microtime());
$output = date( Y/m/d H:i:s ,$sec). " /" . $usec;
关于<代码>microtime()的工程详情,见手册网页。
这是我的方法。
list($usec, $sec) = explode(" ", microtime());
$time = date("Y-m-d H:i:s:",$sec).intval(round($usec*1000));
echo $time;
自PHP 7.3hrtime
以来,已备妥。
这意味着,在无任何微观问题的情况下,你可以在纳米秒中使用高分辨率的时间。 (例如,测试之间变化的系统锁)
因此,现在,你可以在64个轨道平台上可靠地获得武器,这些平台有:
intval( hrtime(true) / 1000000 ); //Convert nanosecond to ms
先前答复中描述的格式。
