How can the issue of session management be addressed in PHP applications following REST architecture?

Issue: In PHP applications following REST architecture, session management can be addressed by using tokens or JWT (JSON Web Tokens) for authentication and authorization instead of relying on traditional session management with cookies. Code snippet:

<?php
// Generate JWT token for authentication
function generateJWT($user_id) {
    $payload = array(
        "user_id" => $user_id,
        "exp" => time() + 3600 // Token expires in 1 hour
    );
    $jwt = JWT::encode($payload, 'secret_key');
    return $jwt;
}

// Verify JWT token for authorization
function verifyJWT($jwt) {
    try {
        $decoded = JWT::decode($jwt, 'secret_key', array('HS256'));
        return $decoded->user_id;
    } catch (Exception $e) {
        return null;
    }
}

// Example of generating and verifying JWT token
$jwt = generateJWT(123);
$user_id = verifyJWT($jwt);

echo "JWT token: " . $jwt . "\n";
echo "User ID: " . $user_id . "\n";
?>
