Hướng dẫn php microtime to minutes

I have a session which contains microtime(true) value. like below:

Yii::app()->user->setState('portal_logged_time', microtime(true));

Now i want to add 15 minutes in above session, but it should remain in microtime.

$starttime = Yii::app()->user->getState('portal_logged_time');
// Now i want to add microtime of 15 minutes into $starttime
$endtime = // i want to do something like this ($starttime*15*60); 

I have tried this but it is not working $starttime*15*60.

So how to achieve that?

After that i am trying to fetch remaining minutes and seconds:

$duration = $endtime-$starttime;

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

Values provided by microtime() are in seconds. So you should simply do:

$endtime = $starttime + 15*60;

Note that the timestamp returned is "with microseconds", not "in microseconds". This is especially good to know if you pass 'true' as the parameter and then calculate the difference between two float values -- the result is already in seconds; it doesn't need to be divided by a million.

";

echo date('Y-m-d h i s', $temp);

$sum = round($temp) + 900;

echo "
";
echo date('Y-m-d h i s', $sum);

?>

like this:

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

Manually :

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

Try this:

$starttime = round(microtime(true) * 1000);

$endtime = $starttime + 15*60*1000;

From the PHP.net article on date() which is similar to gmdate(), except that the time is returned in GMT:

Since this function only accepts integer timestamps the u format character is only useful when using the date_format() function with user based timestamps created with date_create().

Use something like this instead:

list($usec, $sec) = explode(' ', microtime()); //split the microtime on space
                                               //with two tokens $usec and $sec

$usec = str_replace("0.", ".", $usec);     //remove the leading '0.' from usec

print date('H:i:s', $sec) . $usec;       //appends the decimal portion of seconds

Which prints: 00:00:03.1745569706

If you want you can use round() to round the $usec var even more.

If you use microtime(true) use this instead:

list($sec, $usec) = explode('.', microtime(true)); //split the microtime on .

What is the PHP Microtime function?

The PHP microtime function is the one that returns the current Unix timestamp with microseconds. And interestingly, you can use the said function to get time in other units as well, such as seconds. So, here you’ll see how the PHP microtime works, how you can use the same for converting time units, and which other function returns time in seconds.
