Alias does not work with php

[tapir]

can I then use other scripts from /path/to/otherscript

my document root looks like this:

phpbb/
wordpress/
phpmyadmin/
piwik/

but I only want wordpress to be accessible from the mydomain.com. Others
should be accessible from mydomain.com/phpbb and so on...

maybe I should have asked this from the start :) how can I achieve this?
