What are the advantages of using object-oriented programming principles in PHP to create more secure and maintainable code?

Using object-oriented programming principles in PHP can help create more secure and maintainable code by encapsulating data and functionality within objects, which reduces the chances of accidental data manipulation or unauthorized access. Additionally, OOP allows for code reusability through inheritance and polymorphism, making it easier to maintain and update code in the future. By using classes and objects, developers can organize their code in a more structured and modular way, leading to better readability and easier debugging. 

<?php
// Example implementation of using OOP principles in PHP

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 setUsername($username) {
        $this->username = $username;
    }

    // Additional methods for user authentication and authorization can be added here
}

$user = new User("john_doe", "password123");
echo $user->getUsername();
?>
