[PHP] time() TIMER in seconds or just numbers
what does time();
$t1 = time();
{
do something
}
$t2 = time();
$end_time = $t2 - $t1;
echo $end_time;
what does $end_time represent?
how do you determine the next 5 mins?

The number of seconds it took to do something.
how do you determine the next 5 mins?
Assuming you mean what will time() return in 5 minutes time?...
$five_minutes_time = time() + 300; // 300 seconds in 5 minutes
If you mean something else please try rephrasing the question.

$end_time is not a great name for it: it's the time (number of
seconds) it took to go from $t1 to $t2. $duration might be better.

Eh? time() + 300 is five minutes from now.

Re: [PHP] time() TIMER in seconds or just numbers
When someone does that, it means the execution time between $t1 and $t2...

When someone does that, it means the execution time between $t1 and $t2... Is that for my benefit?

Okey, but you understand the purpouse of it?

Please stop top-posting. I'm fully aware of what it's for == I am aware of its purpose. My point was that time() gives you seconds since the UNIX epoch, whereas microtime(true) will give you more accurate results if you are looking to benchmark a script. If your script takes a few minutes and you don't really care about measuring those milli/micro seconds, then time() should suit your needs just fine. However, if your script can perform an iteration in less than one second, you have already eliminated the usefulness of time() for benchmarks. -- // Todd -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

how do you determine the next 5 mins?
So if you haven't deduced the answer from other replies, this would
probably be more readable:
$start_time = time(); //or microtime()
//do something
$end_time = time(); //or microtime()
$duration = $end_time - $start_time;
echo $duration;

Don't forget--microtime() without the boolean true as an argument
will split the result into two parts. Using true as the argument
(minus quotes, of course) gives you a floating-point representation of
seconds/milliseconds/etc.
