setToken($token); function generateToken() { return bin2hex(random_bytes(32)); } ?>
setToken($_POST['token']); if ($user->validateToken()) { // Token is valid, allow access to restricted page } else { // Token is invalid, deny access to restricted page } ?>In this example, we retrieve the token value from the $_POST superglobal and call the setToken() function to set it in the user session. Then, we call the validateToken() function to check if the token is valid. If it is valid, we allow access to a restricted page, otherwise, we deny access. The package library for the User setToken() function is likely a custom PHP class or framework developed by the application's developers. There are also many third-party PHP libraries that provide similar functionality, such as the PHPJWT library for JSON Web Tokens.
