In cases where session variables are not displaying or being passed correctly, what alternative methods or approaches can be used to ensure the variables are accessible in subsequent PHP scripts?

If session variables are not displaying or being passed correctly, an alternative approach is to use cookies to store and retrieve the necessary data. Cookies can be set with the `setcookie()` function and accessed using the `$_COOKIE` superglobal in subsequent PHP scripts.

// Set a cookie with the desired data
setcookie('variable_name', $variable_value, time() + 3600, '/');

// Access the cookie in subsequent PHP scripts
$variable = $_COOKIE['variable_name'];
