What are the potential pitfalls of changing the structure of a class during runtime in PHP?

Changing the structure of a class during runtime in PHP can lead to unexpected behavior, errors, and difficulties in debugging. It can also make the code harder to maintain and understand. To avoid these pitfalls, it is recommended to design classes with a clear and stable structure from the beginning and avoid altering it dynamically. 

// Avoid changing the structure of a class during runtime
// Instead, design classes with a clear and stable structure from the beginning

class MyClass {
    private $property;

    public function __construct($value) {
        $this->property = $value;
    }

    public function getProperty() {
        return $this->property;
    }
}

$instance = new MyClass('Hello');
echo $instance->getProperty(); // Output: Hello
