As Richard [Q...] implies, the only people who are going to be able
to "open[ing] a terminal window" to your site are those you've given
that level of access to. A "user" only has access to the
server-parsed php files (whether they are using a browser or
telnetting directly to port 80). They don't have filesystem access.

Now, if you have open/poorly secured ftp/sftp/scp/telnet/ssh ...
access, someone who can utilize that route will have fairly
unconstrained access to your site and its contents. However, that's
basic access control security and not a php-specific issue.

If it's contractors/co-workers who have filesystem access to the
site, in order to manage content, then you have a trust issue. 

If your concern is with others "on the site" (e.g., a shared hosting
environment) then you have a basic hosting security issue, and
problems well beyond the control/scope of anything php.
