        if(is_array($keys)) return false;
        foreach (array(' ', '&nbsp;', '\n', '\t', '\r', '"','\'','_') as $strip)
            $keys = str_replace($strip, '', (string) $keys);
        $keys = trim(preg_replace('/\W+/', '-', $keys), '-');
        $keys = strtolower(str_ireplace('input','',$keys));

It seems like str_ireplace('input', '', $keys) can also be of type array; however, parameter $string of strtolower() does only seem to accept string, maybe add an additional type check?

        return $keys;
    }

            $key = call_user_func($callable,$key);
            $map[$key] = $value;
        }
        return $map;
