In Symfony, to deep copy objects, you can utilize the `clone` keyword along with implementing the `__clone()` method in your class to ensure that all properties are properly duplicated. Here is an example of how to achieve a deep copy of an object:
city = $city;
$this->postcode = $postcode;
}
}
class User {
public $name;
public $address;
public function __construct($name, Address $address) {
$this->name = $name;
$this->address = $address;
}
public function __clone() {
// Deep clone the Address object
$this->address = clone $this->address;
}
}
// Creating an original User object
$originalUser = new User('John Doe', new Address('New York', '10001'));
// Cloning the original User object to create a deep copy
$clonedUser = clone $originalUser;
// Modifying the cloned user's address
$clonedUser->address->city = 'Los Angeles';
// Outputting cities to show the effects of deep copy
echo "Original User City: " . $originalUser->address->city; // New York
echo "Cloned User City: " . $clonedUser->address->city; // Los Angeles
?>
