class User { public $username; public $password; public $email; function __construct($username, $password, $email) { $this->username = $username; $this->password = $password; $this->email = $email; } } $user = new User("john_doe", "password123", "john_doe@email.com");
class User { private $username; private $password; private $email; function __construct($username, $password, $email) { $this->username = $username; $this->password = $password; $this->email = $email; } public function getUsername() { return $this->username; } public function setUsername($username) { $this->username = $username; } } $user = new User("jane_doe", "password456", "jane_doe@email.com"); $user->setUsername("jane_doe_new_username"); echo $user->getUsername(); // outputs "jane_doe_new_username"In this example, we create a new User object with a username "jane_doe", a password "password456", and an email address "jane_doe@email.com". We then create two public methods, getUsername() and setUsername(), that allow us to access and modify the username property of the User object. We demonstrate this by setting and getting the username property of the instantiated user object. The package library used in this code may vary depending on the overall application, but it may include packages such as PHPUnit for testing, PHPMailer for handling email, and an ORM such as Doctrine for interacting with a database.
