note 29978 added to function.system

I have a question. I am new to php, but know how to program C based languages. I have a question on the system call. The code I am using is: <? system("snortsnarf"); ?> Now, when I run from the command line (This is a Linux system running apache) and type php test.php the code works as expected. When I try to access it from the web, nothing happens, the script snortsnarf does not get executed. Does anyone know why? The script is located in my /usr/sbin/ dircetory. Any help is appreciated. -- http://www.php.net/manual/en/function.system.php http://master.php.net/manage/user-notes.php?action=edit+29978 http://master.php.net/manage/user-notes.php?action=delete+29978 http://master.php.net/manage/user-notes.php?action=reject+29978
