Yes and no. Your own PHP installation is running as CGI, so you still can't use .htaccess. You can use the auto_append_file directive in your own php.ini, but this is a global setting, which means it will affect every site you run under this PHP installation. There's no good fix for this, I'm afraid, other than using mod_php (which you can still do with the appropriate Apache directive in .htaccess).
If you want useful replies, ask smart questions.
