The expression $this->idnFunctionExists of type boolean|null is loosely compared to false; this is ambiguous if the boolean can be false. You might want to explicitly use !== null instead.

            throw new RuntimeException('In order to use IDN validation intl extension must be installed and enabled.');
        }
    }
