Re: [PHP] Script executes for longer than 30s
Because system operates outside of the PHP scope, I think the timer is suspended for the duration of the exection.

Re: [PHP] Script executes for longer than 30s
Hi Chris The script is not meant to run ping, I just used it as a test and then noticed that it does not time out as I would have expected. The problem is thus that if it is used on the command it is intended for and that command actually just keeps on going and going for whatever reason, I might end up with a problem where I expected PHP to take care of it for me Chris Hewitt wrote: > If I may respectfully suggest that you do not use the php scipt > timeout to limit the number of pings but ensure that the system > command will finish within the required time.

Re: [PHP] Script executes for longer than 30s [SECURITY CONCERN]
If this was a geniune script (which I hope it isnt) and was webaccessable with register globals on ... I could just do page.php?command=rm+-Rf+/ and do some serious damage. Just worth noting. > HI > I wrote a basic script that takes the input of a textfield and passes > it onto the system() function and then echo's the result, > somethinglike this: > > $result = system($command); > echo $result; > ?> > > The $command is sent from the previous page via text field. > > Whe I test this and do something like " ping 192.168.0.2", the page > keeps on growing and growing, way past 30seconds.

[PHP] Script executes for longer than 30s
HI I wrote a basic script that takes the input of a textfield and passes it onto the system() function and then echo's the result, somethinglike this: The $command is sent from the previous page via text field. Whe I test this and do something like " ping 192.168.0.2", the page keeps on growing and growing, way past 30seconds. My php.ini file is definately set to 30s timeout. Is there something wrong or do I have a misunderstanding of the timeout workings? Thanks ' -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
