What are the implications of using closures in PHP for accessing and modifying private properties of a class instance?

When using closures in PHP to access and modify private properties of a class instance, it is important to be cautious as it can potentially violate encapsulation and lead to unexpected behavior. One way to address this issue is to create public getter and setter methods within the class to properly encapsulate the private properties and control their access. 

class MyClass {
    private $privateProperty;

    public function getPrivateProperty() {
        return $this->privateProperty;
    }

    public function setPrivateProperty($value) {
        $this->privateProperty = $value;
    }
}

$instance = new MyClass();
$closure = function() use ($instance) {
    $instance->setPrivateProperty('new value');
};

$closure();
echo $instance->getPrivateProperty(); // Output: new value
