What is the difference between using $event->__toArray() and (array) $event to convert an object to an array in PHP?

Using `$event->__toArray()` is a specific method call that expects the object to have a `__toArray()` method defined, which may not be a standard PHP convention. On the other hand, `(array) $event` is a type casting technique that converts the object into an array using the properties of the object. If the object does not have a `__toArray()` method but has public properties, using `(array) $event` is a more general and reliable way to convert the object to an array.

// Using (array) $event to convert an object to an array
$array = (array) $event;
