What are some alternative methods to PHP sessions for managing user data in a web application?

Using alternative methods to PHP sessions for managing user data in a web application can improve scalability and security. One common alternative is using JSON Web Tokens (JWT) to store user data in a token that is signed and encrypted. This allows for stateless authentication and authorization, making it easier to scale your application across multiple servers. 

// Example of generating a JWT token with user data
use Firebase\JWT\JWT;

$secret_key = "your_secret_key";
$user_data = array(
    "user_id" => 123,
    "username" => "john_doe"
);

$jwt = JWT::encode($user_data, $secret_key);
echo $jwt;
