Thank you all for your collective help. I was very frustrated. This list helped me find the answer quickly and once again PHP is slowly all beginning to make sense. The default values enable safe-mode and that is what Jason was trying to get me to check. Thus when the php.ini wasn't where php thought it was then the engine just used the default values. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] I think this is a bug...cant use exec commands.
May be you can look at exec() function:

I know this doesn't solve the problem but gives you an option to
workaround the problem.
The curious thing about the warning message is: where are the backquotes
in your code??

I can make this script executable via chmod 700 mem.php and run it directly
via the command line. Only then I can get it to work on my redhat 9 machine.
The problem is I call this script from another script to plot out the data

The warning would be applicable if any php.ini file on my system had Safe
Mode enabled. As the bug people said shell_exec() == ``. But that applies
if anywhere on my box safemode was enabled. I have spent 4 solid days
looking and verifying there is no safe mode enabled on my box. It's an
internal monitoring server there is absolutely no need for safe mode. This
is what is in my PHP.ini
; Safe Mode

safe_mode = Off
safe_mode_gid = Off
Can someone tell me if they can run that script on their *nix machine? I'm
running php 4.32 apache 2.0 server on a up-to-date redhat 9 server. I don't
think this script can be run from another program.

I tell you the truth. I have only 1 php.ini. There are other ini files I
have looked at but I have not found anything in them about safe mode.
Everything has been double or triple checked. Still not able run any
shell_exec commands from the command line.
I need the output from free so if I use exec()

Exec complains that free is not in /usr/local/php/bin/ directory. ( I
think that's the directory but whatever it was, it wasn't pointing at the
web directory where my script is.) Really someone should try this script.
It's harmless. 'Free' is a nix command.
