im assusing your talking about php with apache if so use php_admin_value 
openbase_dir, i would also use php-exec-dir patch, to block all executables 
so they cant jump outside to other dirs with normal binarys.

However, when browsing the web, I found an article
which said that "it requires an expert to lockdown
php" (Sorry, but I can't quite recall the URL).
While I am not a novice, I am defintely not an
expert either - expecially on security issues.
So, I'd like to ask the members of this list - how
difficult is it to secure php ? Do you really need
a security "expert" to do this ?
P.S. The few hundred students mentioned above are
IT students ;-)
I think one thing worth mentioning is that in
*most* PHP installations, the PHP code will be
executed as the web server user.
This means that the several hundred IT students
will be able to read each other's code and write
to each other's datastores. Most students will
have to chmod a+w any files or directories
that will be modified by their PHP code.
There are several ways around this, but it does
take more configuration and security smarts to
implement. This "vulnerability" (if you can call
it that) exists in just about every multi-user web
system out there, so it's probably worth your time
to investigate different security mechanisms.
