What are the potential drawbacks of using a self-modifying code approach like the one demonstrated in the PHP class?

Potential drawbacks of using self-modifying code include decreased readability, increased complexity, and potential security vulnerabilities. Additionally, self-modifying code can make debugging and maintenance more challenging as the code's behavior may change dynamically. 

// Instead of using self-modifying code, consider using a more structured and maintainable approach such as creating separate functions or classes to handle dynamic behavior. This can improve readability, maintainability, and security of the code.

// Example of using a separate function to handle dynamic behavior
function calculate($operation, $num1, $num2) {
    switch ($operation) {
        case 'add':
            return $num1 + $num2;
        case 'subtract':
            return $num1 - $num2;
        case 'multiply':
            return $num1 * $num2;
        case 'divide':
            return $num1 / $num2;
        default:
            return 'Invalid operation';
    }
}

// Usage
$result = calculate('add', 10, 5);
echo $result; // Output: 15
