The term 'column' makes a lot of sense for PDO working with database
columns, but there is no concept of a 'column' in the array structure or
PHP as a whole, outside of database related functions.
In the case of this addition, I do indeed like array_pluck as well, as
column feel like an overloaded term.
While casting around for other array_* names, I remembered that
array_keys() can take a second (and third) argument. With it, the
function returns all keys indexing a given value.
What we're discussing here is basically a dual to that: return all
values indexed by a given key.[*]
If the duality is continued, then what we get is
array_values(array $input[, mixed $key])
(A third $strict argument would probably do more harm than good: the key
can only be an integer or a non-numeric string, and using the same type
coercion rules would smooth out differences in the $key argument.)
[*] Yes, I know the symmetry isn't perfect, and why; the question is
whether the difference is more likely to result in "Well, duh!" or "WTF?!".
