What are some best practices for documenting PHP classes?

When documenting PHP classes, it is important to provide clear and comprehensive descriptions of the class itself, its properties, methods, and any parameters or return values. Use PHPDoc comments to document each element within the class, including data types, descriptions, and any relevant information. Additionally, follow a consistent naming convention for class names, properties, and methods to make the code easier to understand and maintain. 

/**
 * Class User
 * Represents a user in the system.
 */
class User {
    /**
     * @var int The unique identifier for the user.
     */
    private $id;

    /**
     * @var string The username of the user.
     */
    private $username;

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

    /**
     * Get the user's unique identifier.
     * @return int The user's unique identifier.
     */
    public function getId(): int {
        return $this->id;
    }

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