PHP provides the foreach loop statement that allows you to iterate over elements of an array or public properties of an object .

I surprised that nobody noticed the syntax error in the foreach.

If you want to use the endforeach style, you can change your code like this (this is called Alternative Syntax):

<section>
    <?php foreach ($_SESSION['answers'] as $question => $answer): ?>
        <p>
            <?php echo "$answer <br/>"; ?>
        </p>
    <?php endforeach; ?>
</section>

Or if you want to use PHP-way to make a foreach, you can write it like this:

<section>
    <?php foreach ($_SESSION['answers'] as $question => $answer) { ?>
        <p>
            <?php echo "$answer <br/>"; ?>
        </p>
    <?php } ?>
</section>

However, for cleaner HTML & PHP code, I suggest you to write it like this:

<section>
    <?php 
    foreach ($_SESSION['answers'] as $answer) { 
        echo "<p>$answer</p>" . PHP_EOL;
    }
    ?>
</section>

Note that I removed unused $question variable.

You might want to explain what your actual issue is? What happens when you run your code? Error messages? Wrong result? What does $_SESSION['answers'] contain? Do a var_dump($_SESSION['answers']); and check if it contains what you expect.
I'm sorry. I should have thought to include what is happening. I'll edit my post to include that right now.
and the var_dump shows arrays(0).
Do you have session_start() in the top? If not, then the sessions won't be persistent between requests.
Don't use <br /> to style your contents; use CSS instead.
Thank you so much. It's now displaying the answers so that is progress. Just need to figure out how to get the questions there as well. Yes, I do have session_start() at the beginning of the file. When I do a var_dump now it does list the questions in the array.
I have the questions displaying now as well. I only had to add "$question," to the echo. Geez, I have a talent for making things so much more difficult than they have to be. Thank you again for the help.
Way to go brother!
Yes, I have session_start() at the beginning of the file. Thank you. The var_dump lists all the questions in the array. I made a change to my code and my page is now displaying the answers but not the questions
To see your question, maybe you could try make foreach as this: foreach ($_SESSION['answers'] as $question => $answer);
I have it working now - displaying both questions and answers. I added "$questions," in front of $answers in the echo. Thank you for your suggestions and taking the time to try to help me. It seems I can't post a question without it getting voted down. It's very discouraging when my understanding of php is still so minimal that I can't even formulate a plea for help properly.
