What resources or documentation should be provided by PHP classes to ensure successful implementation?

To ensure successful implementation of PHP classes, it is important to provide clear and comprehensive documentation. This documentation should include information on the purpose of the class, its properties and methods, any dependencies or requirements, and examples of how to use the class in different scenarios. Additionally, providing code examples, tutorials, and API references can also be helpful for developers.

/**
 * Class User
 * Represents a user object with properties and methods for managing user data.
 */
class User {
    private $username;
    private $email;

    /**
     * Constructor for User class
     * @param string $username The username of the user
     * @param string $email The email of the user
     */
    public function __construct($username, $email) {
        $this->username = $username;
        $this->email = $email;
    }

    /**
     * Get the username of the user
     * @return string The username of the user
     */
    public function getUsername() {
        return $this->username;
    }

    /**
     * Get the email of the user
     * @return string The email of the user
     */
    public function getEmail() {
        return $this->email;
    }
}

// Example usage of the User class
$user = new User("john_doe", "john.doe@example.com");
echo "Username: " . $user->getUsername() . "<br>";
echo "Email: " . $user->getEmail();
