The expression $info of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using empty($expr) instead to make it clear that you intend to check for an array without elements.

            throw new \RuntimeException("Could not fetch info from APCu");

The call to Table::render() has too many arguments starting with $output.
