I am having a difficult time grasping what this question is asking?

I seem not to understand what the question is asking and as a result, I am unable to solve this problem. Would someone please try to breakdown what is being asked?

story.php 
<?php
session_start();
$word1 = htmlspecialchars($_SESSION['word'][1]);
$word2 = htmlspecialchars($_SESSION['word'][2]);
$word3 = htmlspecialchars($_SESSION['word'][3]);
$word4 = htmlspecialchars($_SESSION['word'][4]);
$word5 = htmlspecialchars($_SESSION['word'][5]);

include 'inc/header.php';

echo '<h1>My Treehouse Story</h1>';

echo '<p>There once was a(n) ' . $word1;
echo ' programmer named ' . $word2; 
echo '. </p>';
echo '<p>This ' .  $word3; 
echo ' programmer used Treehouse to learn to ' . $word4;
echo ' the ' . $word5 . '.</p>';

echo ' <a class="btn btn-default btn-lg" href="#" role="button">Save Story</a>';
echo ' <a class="btn btn-default btn-lg" href="play.php" role="button">Play Again</a>';
echo ' <a class="btn btn-default btn-lg" href="index.php" role="button">Other Stories</a>';


include 'inc/footer.php';

Hi there, Johannes Chitura ! Let's see if I can phrase this a bit differently. We have a $_SESSION variable that has the key "word". At that key there is an array starting with index 1 and extending to 5. If any one of those is empty we want to redirect to play.php and provide it a query string with the one that is missing.

For instance, if $_SESSION['word'][2] is empty, I would expect it to go to this URL: play.php?p=2. Note that it says to set the p parameter equal to the first missing session variable. I might suggest a for loop starting with 1 and running up to and including 5 :smiley:

Hope this helps! :sparkles:
