What best practices should be followed when passing arrays of objects between classes in PHP?

When passing arrays of objects between classes in PHP, it is important to ensure that the objects are properly serialized and deserialized to avoid any loss of data or unexpected behavior. One common approach is to use PHP's built-in serialization functions like serialize() and unserialize() to convert the array of objects into a string representation that can be easily passed between classes. 

class MyClass {
    public function passObjects(array $objects) {
        // Serialize the array of objects
        $serializedObjects = serialize($objects);

        // Pass the serialized objects to another class
        $anotherClass = new AnotherClass();
        $anotherClass->receiveObjects($serializedObjects);
    }
}

class AnotherClass {
    public function receiveObjects(string $serializedObjects) {
        // Unserialize the string back into an array of objects
        $objects = unserialize($serializedObjects);

        // Process the array of objects
        foreach ($objects as $object) {
            // Do something with each object
        }
    }
}
