What potential issues can arise when cookies are disabled for PHP sessions?

When cookies are disabled for PHP sessions, the session ID cannot be stored in a cookie, which can lead to session hijacking or loss of session data. To solve this issue, you can use URL parameters to pass the session ID between pages.

<?php
session_start();

if(!isset($_GET['PHPSESSID'])) {
    $_GET['PHPSESSID'] = session_id();
}

session_id($_GET['PHPSESSID']);
?>
