Oops I catted the wrong file. But the file is exactly the same as mem.php.
[EMAIL PROTECTED] swap]# cat mem.php
<?php
exec("free -b", $data, $result);
$data = str_replace(' ',' ',$data);
$data = str_replace(' ',' ',$data);
$data = str_replace(' ',' ',$data);
$data = str_replace(' ',' ',$data);
$dataArray = explode(' ',$data);
$total = $dataArray[16];
$used = $dataArray[17];
echo $used.chr(10);
echo $total.chr(10);
?>

Subject: RE: [PHP] I think this is a bug...cant use exec commands.
Ok here is my php.ini. directly from /etc/php.ini
; Safe Mode
;
safe_mode = Off
; By default, Safe Mode does a UID compare check when
; opening files. If you want to relax this to a GID compare,
; then turn on safe_mode_gid.
safe_mode_gid = Off
; When safe_mode is on, UID/GID checks are bypassed when
; including files from this directory and its subdirectories.
; (directory must also be in include_path or full path must
; be used when including)
safe_mode_include_dir =
; When safe_mode is on, only executables located in the safe_mode_exec_dir
; will be allowed to be executed via the exec family of functions.
safe_mode_exec_dir = /var/www/html/swap/
I am on a redhat 9.0 machine so I use the locate command after a fresh
updatedb andf this is all the ini files I was talking about.
[EMAIL PROTECTED] swap]# updatedb
[EMAIL PROTECTED] swap]# locate php.ini
/etc/php.ini
/etc/php.ini.rpmsave
/root/php-4.3.4/php.ini-recommended
/root/php.ini.rpmsave
/home/bduke/downloads/php/php-4.3.5/pear/tests/php.ini.tst
/home/bduke/downloads/php/php-4.3.5/php.ini-recommended
/home/bduke/downloads/php/php-4.3.5/php.ini-dist
The php-4.3.5 in not installed yet. I just downloaded it and untarred the
contents in my download directory. We run the program via the web it's for
MRTG graphs. I was using an example I found on the web. Here is the result
when I change line 1 using exec()
[EMAIL PROTECTED] swap]# cat swap.php
<?php
exec("free -b", $data, $result);
$data = str_replace(' ',' ',$data);
$data = str_replace(' ',' ',$data);
$data = str_replace(' ',' ',$data);
$data = str_replace(' ',' ',$data);
$dataArray = explode(' ',$data);
$total = $dataArray[16];
$used = $dataArray[17];
echo $used.chr(10);
echo $total.chr(10);
?>
[EMAIL PROTECTED] swap]# php mem.php
sh: line 1: /usr/local/php/bin/free: No such file or directory
[EMAIL PROTECTED] swap]# pwd
/var/www/html/swap
[EMAIL PROTECTED] swap]# ls ./free
./free
[EMAIL PROTECTED] swap]#
The MRTG will call the program via a cgi script. It calls this program only
when the data is requested that way we save on cycle time.

What are these other ini files you've looked at?
How are you executing this script? Via a webserver or directly using the php
executable? If the former use phpinfo() to find out where php thinks it's
php.ini should be found, if the latter use "php -i". Once you've determined
where your php.ini should be examine its safe_mode settings.
