毫秒到秒或小时或分钟的转换 [英] microtime to seconds or hours or min conversion

问题描述

我在数据库中存储的开始时间为microtime()，结束时间为microtime().

I have the store start time as microtime() and end time as microtime() into database.

现在，我想计算脚本执行秒/分钟/小时所花费的时间.

Now I want to calculate how long the script takes the seconds/minutes/hours to execute.

如何使用PHP?

推荐答案

基本上是这样的:

echo date("H:i:s",$endtime-$starttime);

$endtime-$starttime给出持续时间(以秒为单位)，使用日期格式化输出.听起来像是保存到数据库或从中读取不是您的问题，因此我在示例中忽略了这一点.请注意，您必须使用microtime(true)才能使它正常工作，由于microtime()的空格分隔输出，您无法轻松地进行计算.

$endtime-$starttime gives the duration in seconds, date is used to format the output. sounds like saving to and reading from a database isn't your problem here, so i left that out in my example. Note that you'll have to use microtime(true) to get this working, with the space-seperated output of microtime() your can't do calculations that easy.

编辑:您也可以自行进行所有计算.只是这样的基本数学:

you could do all the calculation on your own, too. it's just basic math like this:

$duration = $endtime-$starttime;
$hours = (int)($duration/60/60);
$minutes = (int)($duration/60)-$hours*60;
$seconds = (int)$duration-$hours*60*60-$minutes*60;
