Yes, but look at his site. He's trying to create an online PHP executor
for people to use. Your suggestions won't help there - it's impossible
to use them to limit access to the files from user-developed code
(evidently executed with eval()) while still making it available to the
installed code.
And limiting things like file functions in his php.ini file will not
only limit the functions for user-developed code, but for the code on
the site itself.
