IMHO what you have described is a bug in PHP, and if I were you, I'd report it as
such. If it's not a bug it at least has a very high WTF factor. Having to use the
cumbersome:
is_array($foo['one']['two']) && array_key_exists('three', $foo['one']['two'])
instead of:
isset($foo['one']['two']['three'])
seems kinda silly to me. I doubt that this is the intended behavior.
