There's no "right" answer to this question (as with anything programming-related) but it should point you in the right direction.
Session support in PHP is accomplished through cookies by default (all of this can be overridden via code). Since you're unlikely to want to travel outside of cookies for your solution, you're restricted to whatever cookies will allow you to do (as with any language).
PHP stores a session-id in a cookie and on the filesystem by default. This means the cookie needs to be set so that your browser sends it to each server during a request, and that each server has access to the server-side store which holds the session data for each cookie.
If all servers share the same DNS name (service.domain.local) your browser will send it regardless, but if they do not (intranet.domain.local and applications.domain.local) you will need to use the session_set_cookie_params() function to set the domain to a common subdomain - i.e. ".domain.local". Be aware that this sends it to every web server matching ".domain.local" so other machines will receive your highly important session-id, so plan this out carefully.
Once the web servers are all receiving the cookie, your PHP installation will need access to a common storage location. By default, PHP stores cookies in a local directory with the filename being the session-id and the contents being the session data. Thus, you'd need to access/share the same directory on all machines or change that behavior. I'd suggest investigating the many ways you can move session storage to a database so all machines have reliable, safe access to the session store - and, you can report on those sessions down the road.
In short, it's a two-pronged approach: set the session cookie up so it reaches all of your servers (again not an issue if they all have the same hostname) and configure PHP to pull session data from one central place.

How do you maintain a session in a PHP quiz script?
All you have to do to maintain a session is start it before you call any variables. Once you've started the session, you can store variables for use in later scripts. Beware though, once the user closes the browser, the sessions' over. I'd use the following SCRIPT 1: <?php // Start session session_start(); // Set some variables (this simulates form input) $_SESSION['answers']['Q1'] = 18; $_SESSION['answers']['Q2'] = 36; $_SESSION['answers']['Q4'] = "Fred"; ?> ============================= Hope that helps...

To clear a session in a web application, you can typically use the session management functions provided by your server-side technology. For example, in PHP, you can call session_destroy() to terminate the session, or in Node.js with Express, you can use req.session.destroy(). Additionally, you can clear session data on the client side by deleting cookies associated with the session. Always ensure to handle user logout properly to maintain security.
