What are common issues with PHP sessions not being passed without cookies?
When PHP sessions are not being passed without cookies, it could be due to the session.use_cookies setting being disabled in the php.ini file. To solve this issue, you can explicitly set the session.use_cookies setting to true in your PHP script.
<?php
// Enable passing sessions without cookies
ini_set('session.use_cookies', 1);
// Start the session
session_start();
// Your code here
?>
