My first suggestion would be to warn these users that this is not 
allowed and ban them from the system if they persist.

There are a couple of things you can try, First you can use apache 
directives to deny access to the file. To do that add the following text 
to the httpd.conf file:

<Files ~ "\.inc$">
   Order allow, deny
   Deny from all
</Files>

This would prevent all files with the .inc extension from being viewed 
via the web.

The second thing I would suggest is to disable access to the system() 
function unless you really really need it. You can do that in the 
php.ini file by using the disable_functions directive. It allows you to 
define a comma-delimited list of functions to be disabled within PHP.

Hope this helps.
