Convert microtime to seconds php

I have the store start time as microtime[] and end time as microtime[] into database.

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

How can I do in PHP?

basically, like this:

echo date["H:i:s",$endtime-$starttime];

$endtime-$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-separated output of microtime[] your can't do calculations that easy.

EDIT: 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;

microtime to seconds or hours or min conversion?

microtime is the name of the php function that return a measure of time in microseconds and basically microseconds can be converted to:

    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 A and a time B, in seconds, then the number of seconds between those two absolute times is:

B - A

If you want to format this number of seconds, you can use date to prettify it.
