apache +php +time limits

[Nichu]

Hello
I set max_execution_t ime to 30 in php.ini file (i also checked in
phpinfo). max_input_time is set to 45.

But when I use in script something like that:

while ( 1 == 1 )
or
for ( $i=0; $i < 100000000000000 000000000000000 00000000000; $i++)

{
echo "\n".$i;
}


it doesn't work - execution of script lasts for unlimited time.

of course I executed it via apache (I read that this limit doesn't work
while executing in console)

is it bug or am i doing something wrong?

regards
nichu

Re: apache +php +time limits

did you restart the server after setting the max execution time?

I suppose you've already checked the most obvious things (restart web
server, run phpinfo() to see if your settings have been applied...).

An alternative could be to use this in the code itself:

<?php
ini_set('max_ex ecution_time', 30); // Seconds
while(TRUE){
}
?>

It works for me where editing php.ini doesn't (e.g. console).

of course I checked phpinfo - i also checked ini_get - and both methods
show me good value (the one I set in php.ini)

ini_set works for me - but i want to limit execution time for all my
users - and rather if I tell them to add this line to their scripts they
won't listen to me ;)

so I need to do it via php.ini

Weird... What OS and server API are you using?

uppps
it was wrong diagnosis :/ sorry for that...
generally limit works but it doesn't last for time specified in php.ini
and it lasts ... well rather quite randomly ...

when I set the limit to lower value (3 seconds) firstly it stopped
script after 7 seconds, 2nd time after ~12 seconds, 3rd time ~9 seconds
and later it last really long (after 25 seconds I stopped it manually)

probably it has something common with caching but generally sometimes it
lets script working for really long time (much longer than limit in
php.ini stands for)

by the way i'm testing it on mandriva, debian and gentoo...

3 seconds does not necessarily mean 3 real-time seconds. It means at
least 3 seconds of cpu time - which varies in real life, depending on
what else is going on in the system.

As I understand it, the execution time limit is in CPU seconds, not
wall clock seconds, and only for the PHP process. So if your script
is doing a lot of stuff that doesn't occupy much CPU (*in PHP*),
such as disk I/O, network I/O, DNS lookups, or database calls, it
may last quite a bit longer.

Pull up that page and search for 'CPU', it's there for sure. Thanks for
a lil bit of knowledge ill need down the road.
