What are the benefits of working with classes in PHP?

Working with classes in PHP allows for better organization and structure of code, making it easier to manage and maintain. Classes also promote code reusability, as you can create instances of a class and use them in multiple parts of your application. Additionally, classes enable you to encapsulate data and behavior, leading to more secure and modular code. 

class User {
    private $username;
    
    public function setUsername($username) {
        $this->username = $username;
    }
    
    public function getUsername() {
        return $this->username;
    }
}

$user = new User();
$user->setUsername('john_doe');
echo $user->getUsername(); // Output: john_doe
