    Negative.  It won't inherit permissions, though one might expect
that to make sense.

    No, the best you could do is disable all shell access, or limit
the commands that can be run via the shell, but the latter option is
getting beyond the scope of a PHP question.

    If you're doing it on php1.net, you're safe.  The only damage that
can happen on that server is to your own account.  That's
unfortunately not true of all hosting providers, but you're good
there.  ;-P
