I do not know what is wrong with code? Does anybody see the issue?

for($i=0;$i<5;$i++){ if(empty($_SESSION['word'][$i])) { header('location:play.php?p=2'); } }

story.php 
<?php
session_start();
for($i=0;$i<5;$i++){
  if(empty($_SESSION['word'][$i])) {
    header('location:play.php?p=2');
    }
}
$word1 = htmlspecialchars($_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';

In the for loop you only declare the variable once. 

for($i=0;  i<5; i++){
  if(empty($_SESSION['word'][i])) {
    header('location:play.php?p=2');
    }
}

Dear Tanni Myers,

After trying your improved code i got other errors the variable $i must be used as $i otherwise the webserver will not know the variable.

Nothing wrong with your javascript skills just that this matter is php. Suddle little syntax difference.

Sorry Tanni,

But this right here is php the syntax is a little different from JS. That is what you are coming from. And when i get to the solution remember me post so everyone benefits.
