In what scenarios would it be more beneficial to use classes with private methods over standalone functions in PHP programming?

Using classes with private methods can be more beneficial in scenarios where you want to encapsulate functionality within a specific class and prevent direct access to certain methods from outside the class. This can help in maintaining code organization, reducing code duplication, and improving code reusability. Private methods in classes can also help in enforcing data encapsulation and ensuring that certain methods are only used within the context of the class. 

class Calculator {
    private function add($a, $b) {
        return $a + $b;
    }

    public function calculateSum($num1, $num2) {
        return $this->add($num1, $num2);
    }
}

$calculator = new Calculator();
echo $calculator->calculateSum(5, 3); // Output: 8
