I see what you're getting at, but in my opinion the WTF factor is
too high on this one -- the change from inspecting the outermost
elements to those a level down is too much to load on to a single
extra parameter in my opinion.
However, I do wonder if a related name may not be the way to go,
since it is similar in that both are extracting values from the
array -- perhaps:
array_inner_values($array, $key);
or
array_subvalues($array, $key);
Also, I wonder if there might be scope for multiple $key parameters,
to extract values from defined positions at even lower levels, so
that, for example:
array_whatever($array, 'colour', 'orange');
would return all sub-elements addressed as $array['colour']['orange'];
(Also, also: how would you see this proposal in relation to the
one for array_part(), should some version of that gain approval?)
Cheers!
Mike
