What are the potential issues with accessing private properties in PHP classes for JSON serialization?

When accessing private properties in PHP classes for JSON serialization, the properties may not be directly accessible outside the class, leading to serialization errors. To solve this, you can create public getter methods for the private properties that need to be serialized. 

class MyClass {
    private $privateProperty = 'value';

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

$obj = new MyClass();
echo json_encode(['privateProperty' => $obj->getPrivateProperty()]);
