How can utilizing cookies as an alternative to PHP sessions potentially resolve issues related to user authentication and session persistence?

Using cookies as an alternative to PHP sessions can resolve issues related to user authentication and session persistence by allowing the server to store session data on the client's browser rather than on the server. This can help reduce server load and improve scalability, as well as provide better control over session expiration and persistence. 

<?php
// Set a cookie with session data
setcookie('session_id', $session_id, time() + 3600, '/', 'example.com', false, true);

// Retrieve session data from cookie
$session_id = $_COOKIE['session_id'];

// Validate session data
if(validate_session($session_id)) {
    // User is authenticated
} else {
    // User is not authenticated
}
?>
