That's the only thing browsers can open.

You can NOT get PHP, cgi, jsp, sql, or any other server side files. They
execute on the server and output html. Httrack does not convert anything.

If you actually got php, the server was returning the files instead of
executing them, and they probably shutdown the site to fix the problem.

Just update, the php will be deleted and replaced with html
