Not quite sure we need array_find(). If we can have in_array() set
the array pointer to point to the entry found, one can get the key
by using key(). If in_array() also searches from the pointer onwards,
one can find all entries with the value by doing:

while (in_array($val, $arr)) {
        $keys[] = key($arr);

I would prefer this rather then adding array_find() I think. If we
add array_find() I want similar functionality there. If not, I would
like an option for returning an array with all entries with the value.
