how to display next array value on button click?

Question

I have a session array containing lessonid, lesson name and description.

<?php
include "db.php";
$_SESSION['lesson_ids'];
?>


<table>
<tr><td>Lesson name </td> <td> description </td></tr>
<tr><td><input type="button" name="next" value="next">
</table>

In that session array, I have 3 sets of data. I want to display one lesson in the current page.

When I click next the button, I need to display the next one.

How can this be done?

How is this related to mysql? Where is the HTML form to submit the button? What is the structure of the session array $_SESSION['lesson_ids']; ? — Kaken Bok

Slightly related: Wouldn't it make sense to make this part of the url instead? /lesson/1/chapter/2/page/3 — Bailey Parker
