Question

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?

Answer 1

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;
