In PHP, how do I deep copy objects in Laravel?

In Laravel, deep copying objects can be done using the `clone` keyword. This allows you to create a new instance of an object that is a copy of the original. However, you need to ensure that any nested objects are also cloned to create a complete deep copy. Below is an example of how to achieve this:


        // Sample class to demonstrate deep copying
        class Address {
            public $city;
            public $state;

            public function __construct($city, $state) {
                $this->city = $city;
                $this->state = $state;
            }
        }

        class Person {
            public $name;
            public $address;

            public function __construct($name, Address $address) {
                $this->name = $name;
                $this->address = $address;
            }

            // Method to deep copy the person instance
            public function deepCopy() {
                return new Person($this->name, clone $this->address);
            }
        }

        // Create a new Person object
        $original = new Person('John Doe', new Address('New York', 'NY'));

        // Deep copy the original object
        $copy = $original->deepCopy();

        // Modify the copy's address
        $copy->address->city = 'Los Angeles';

        // Original object remains unchanged
        echo $original->address->city; // Outputs: New York
        echo $copy->address->city; // Outputs: Los Angeles
