looping through the $_SESSION['word'] array to search for an empty value...

*Edit I resolved this below...

story.php
<?php
session_start();

$words = $_SESSION['word'];

foreach ($words as $key => $value) {
    if (!isset($words)) {
        header('Location: play.php');
        exit();
    } else if (empty($value)) {
        header('Location: play.php?p=' . $key);
        exit();
    }
}

$word1 = htmlspecialchars($_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="index.php" role="button">Other Stories</a>';
