class Person { public $name; public $age; } $person = new Person(); $person->name = "John"; $person->age = 25;
class User { private $username; private $password; public function __construct($username, $password) { $this->username = $username; $this->password = $password; } public function getUsername() { return $this->username; } public function getPassword() { return $this->password; } } $user1 = new User("john", "1234"); $user2 = new User("jane", "5678");This code creates a User class with private properties for username and password. It also has a constructor method to set these properties when a new instance is created. It also has getter methods to retrieve these properties. Two instances of the User class are then created with different username and password values. As for determining package library, it depends on what specific library or framework the code is being used in. The code examples above are just using basic PHP object-oriented programming and do not require any external libraries. However, if you are using a popular PHP framework like Laravel or Symfony, you may need to use their built-in object creation methods or rely on third-party libraries like Composer to handle object instantiation.
