Sending variables from one PHP page to another

Question

I\'m building a quiz web application that is dynamically generated from a database on my server. I have pretty much implemented all the functionality, the only missing piece is

Answer 1

First of all, tackle one problem at a time first the list of question working then the authentication.

You should use GET because:

• $_SESSION is to store things specific to a given user its behaviour and authentication information such as a token.
• $_POST is for code that modifies the server side (here you only load things from the database).
• $_GET is to retrieve server-side information which is exactly your case.

Here loading a question is not something that should be different from one user to another. It will not directly modify something on the server-side. This is why you should use GET. Using something else will work but it is not the proper way to do it.

So basically what you change is:

echo '' . $row['title'] . '
';

by

echo '' . $row['title'] . '
';

And in you quizz page you can now know the id of the question (stored by default in $_GET["qid"]) and do whatever you want with it. This of course can be applied to other variables.
