microtime to seconds or hours or min conversion
提问by svk
I have the store start time as microtime() and end time as microtime() into database.
我将商店开始时间作为 microtime() 和结束时间作为 microtime() 进入数据库。
Now I want to calculate how long the script takes the seconds/minutes/hours to execute.
现在我想计算脚本执行需要多长时间的秒/分/小时。
How can I do in PHP?
我可以在 PHP 中做什么？

basically, like this:
基本上，像这样：
echo date("H:i:s",$endtime-$starttime);
$endtime-$starttimegives the duration in seconds, dateis 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.
$endtime-$starttime以秒为单位给出持续时间，日期用于格式化输出。听起来像在数据库中保存和读取不是你的问题，所以我在我的例子中忽略了这一点。请注意，您必须使用microtime(true)才能使其正常工作，因为空格分隔的输出microtime()不能那么容易地进行计算。
EDIT:you coulddo all the calculation on your own, too. it's just basic math like this:
编辑：您也可以自己完成所有计算。这只是像这样的基本数学：
$duration = $endtime-$starttime;
$hours = (int)($duration/60/60);
$minutes = (int)($duration/60)-$hours*60;
$seconds = (int)$duration-$hours*60*60-$minutes*60;

微时间到秒或小时或分钟的转换？
microtime is the name of the php function that return a measure of time in microseconds and basically microseconds can be converted to:
microtime 是 php 函数的名称，它以微秒为单位返回时间度量，基本上微秒可以转换为：
1 milliseconds = 1,000 microseconds
1 second = 1,000,000 microseconds
1 minute = 60,000,000 microseconds
1 hour = 3,600,000,000 microseconds
or
1 microsecond = 0.001 milliseconds
1 microsecond = 0.000001 seconds
1 microsecond = 0.0000000166666667 minutes
1 microsecond = 0.000000000277777778 hours

function formatPeriod($endtime, $starttime)
{
$duration = $endtime - $starttime;
$hours = (int) ($duration / 60 / 60);
$minutes = (int) ($duration / 60) - $hours * 60;
$seconds = (int) $duration - $hours * 60 * 60 - $minutes * 60;
return ($hours == 0 ? "00":$hours) . ":" . ($minutes == 0 ? "00":($minutes < 10? "0".$minutes:$minutes)) . ":" . ($seconds == 0 ? "00":($seconds < 10? "0".$seconds:$seconds));
}

If you have a time Aand a time B, in seconds, then the number of seconds between those two absolute times is:
如果你有一个 timeA和一个 time B，以秒为单位，那么这两个绝对时间之间的秒数是：
B - A
If you want to format this number of seconds, you can use dateto prettify it.
如果要格式化这个秒数，可以使用date美化它。
