In the provided code snippets, what are the best practices for ensuring proper communication between classes and objects to avoid errors like "Trying to get property of non-object"?

When trying to access properties or methods of an object in PHP, it's important to ensure that the object exists before attempting to access its properties. To avoid errors like "Trying to get property of non-object", you can use conditional checks to verify the object's existence before accessing its properties. 

// Check if the object exists before accessing its properties
if ($object instanceof ClassName) {
    $value = $object->property;
    // Do something with $value
} else {
    // Handle the case where the object does not exist
}
