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

Use $_GET.

First, you're going to want to change this line

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

To something like this:

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

And then in quiz.php, retrieve the appropriate quiz using $_GET['id'] as your primary key to look it up in the database.

You should store your quiz title there too (in the db).

$_GET is appropriate here because you're just using an ID to determine which quiz to display. There's no need for confidentiality here. You would use $_POST when you're submitting form data which alters the database. $_SESSION is useful for storing basic login info and other stuff that must persist across multiple pages for the life of the session, such as wizard forms.
