Script timeout

shawjames

I have a complex script that we run once per day. I have re-wrote it many times trying to optimize. Sometimes it runs just fine, other times it times out. The script is run from a browser (IE6), and after 45 seconds it stops loading.

I have tried setting the:

set_time_limit ();

to something high, like 600... but it still times out at 45 seconds. I only need it to run for about 60 seconds.

Is this a browser issue?

I have tried sending output every few seconds... but it still times out at 45 seconds.

any ideas?

You can try:

set_time_limit(0);

Tried this, but same result. Times out at 45 seconds.

That's interesting. Okay, try this script:

<?php
set_time_limit(50);
for ($i = 0;; ++$i)
{
    echo $i . "<br />\n";
    sleep(1);
}
?>

If it still times out at 45 seconds, then perhaps you are running in safe mode, or it is a browser problem (I tested with Firefox 2.0.0.14).

well that test script worked, it actually kept running past 500... I do not think the time on the sleep command counts toward the max exec. time (http://us.php.net/manual/en/function.set-time-limit.php#75557)

Must be a problem with my script. There are quite a few large SQL data pulls, would this cause a timeout?

hmm... yes, the results differed when I switched to test on Linux.

Unlike the case for sleep(), the PHP manual makes it clear that that would not cause a timeout:
"Any time spent on activity that happens outside the execution of the script such as system calls using system(), stream operations, database queries, etc. is not included when determining the maximum time that the script has been running."
