No E_NOTICE at all.

There's no clear example stating this, but:

echo "$array[key]";

Is EXACTLY the same as:

echo "{$array['key']}";

With no notices being generated (I know since I always debug using E_ALL).
It's probably faster too, since I guess { "activates" a more complex parser.

Of course, that's the same as:

echo $array['key'];
