[PHP-INST] PHP in selected directories?

[Thomas 'Moreaulf' Gullgården]

Hi there.

I rather quick question for someone who knows hopefully.
I got a apache webserver running PHP (with other irrelevant stuff too) and I
want to be able to deny PHP-scripts to be served ("executed"). I know I can
use the doc_root option in php.ini but then I must use directories outside
that path.

Can I somehow make, for example, no php-scripts runable from the directory
/home/username/public_html/ ?
(What I want is that some users should be able to mess around with php and
some not :)

Thanks in advance,
/Thomas
