How to convert microtime to seconds in 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.

Definition and Usage

The microtime() function returns the current Unix timestamp with microseconds. By default, this function returns a string value which contains microseconds and seconds separated by space (msec sec).

Syntax

microtime($get_as_float)

Parameters

Return Values

PHP microtime() function returns the current Unix timestamp. By default this returns a string value in the form msec sec. If you pass the boolean value true as a parameter to this method, it returns the current time in seconds since the Unix epoch accurate to the nearest microsecond.

PHP Version

This function was first introduced in PHP Version 4 and, works with all the later versions.

Example

Following example demonstrates the usage of the microtime() function −

Live Demo

<?php
   $time = microtime();
   print($time);
?>

This will produce following result −

0.60664200 1589305212

Example

Lets try to set the get_as_float value to true −

Live Demo

<?php
   $time = gettimeofday(true);    
   print_r($time); 
?>

This will produce following result −

1589298812.5101

Example

Live Demo

<?php
   $time_start = microtime(true);
   usleep(100);
   
   $time_end = microtime(true);
   $time = $time_end - $time_start;
   
   echo "Did nothing in $time seconds\n";
?>

This produces the following result −

Did nothing in 0.0018141269683838 seconds
