I don't see anythign wrong with using that one or that way of installing it, but I was just saying that the method names and parameters are different from the older extension and to just be aware of that. Old extension: http://us2.php.net/manual/en/book.memcache.php New extension: http://us2.php.net/manual/en/book.memcached.php The naming confusion is unnecessary but it exists so there's not really too much you can do about it :P
