You will usually have access to .htaccess, though some hosts will not allow the use of mod_rewrite or other modules that they perceive as costing them too much time/money in "customer support." You will almost never have access to httpd.conf, since this is where the "sharing" of the host is set up. I'm not sure about php.ini, but if that is typically done at the server level, then you won't have access to it, either.
