I used wamp, so the path is base on the installing path of wamp application.

Go to
[your wamp root path, something like D:\wamp]\apps\phpmyadmin[version id, something like 2.11.6]\config.inc.php
example:

D:\wamp\apps\phpmyadmin2.11.6\config.inc.php

After each $i++, admin can add a new remote database server for local access.

I guess normally we keep the first one for localhost database.
