Question

I’m executing a PHP script that takes about a minute to finish and although the default time limit is set to 30 seconds, the script continues its execution after that limit.
I found out, that the limit only affects the time that is spent inside the script itself and not the time spent in library functions like database queries etc.

Is there a way to find out the time that is actually spent inside the script? I tried to use getrusage, but it doesn’t seem to return the appropriate values for this problem.

Example:

<?php
$time = microtime(TRUE);
sleep(100);
echo 'Time: ', microtime(TRUE) - $time;
?>

The script waits for 100 seconds and does not terminate after the time limit of 30 seconds.
According to the documentation of set_time_limit, the time that is spent inside the sleep function (100 seconds) is not involved in the calculation of the execution time, because it’s an external (library) function.

Answer 1

I just want to know how much of the execution time is spent inside my script and how much is spent in library functions.

Use XDebug Profiler for it.
