Anybody know of any reason not to save a little typing with
empty($array['foo'])
They're different comparisons, array_key_exists will return true if
there is an element with that key *even if it is null or some other
empty() value* (and the logic is reversed, you need !empty()),
isset($array['foo']) is closer but will return false if the value is null.
