"Add one element to the $recommendations array with a value of 'Avocado Chocolate'." ?? How? (stage 5, challenge 3 of 3)

I have read all the other posts to the forum on this question, but none of them make sense to me! Could someone please give me a definitive answer as to what im doing wrong and what i must change.

Here is my code:

<?php

    $recommendations = array(1);


?>

<html>
<body>

    <h1>Flavor Recommendations</h1>

    <ul>
       <?php if (!empty($recommendations)) { ?>
    <ul>
    <?php foreach($recommendations as $flavor) { ?>
        <li><?php echo $flavor; ?></li>
    <?php } ?>
    </ul>
    <?php } else { ?>
    <p>There are no flavor recommendations for you.</p>
    <?php } ?>
    </ul>

</body>
</html>

Hi Joshua,

What you need to do is actually pass the value of 'Avocado Chocolate' into the array like so:

$recommendations = array ('Avocado Chocolate');

<?php

$recommendations = array();
$recommendations[] = 'Avocado Chocolate'; //this is a way to add one more element to the array

?>

<html> <body>

<h1>Flavor Recommendations</h1>

<?php 

/* I found that adding additional closing and opening php tags around html markup a bit hard
   to read so, I refactored the code like this: (note comments are not needed) */

if(!empty($recommendations)) //checks if array is not empty
{
  echo '<ul>'; // start of unordered list

    foreach($recommendations as $flavors) // loops through array displays list of array items
    {
      echo '<li>' . $flavors . '</li>'; // outputs each array item in html list item tag within the unordered list
    }

   echo '</ul>'; //end of unordered list
}
else 
{
  echo '<p> There are no flavor recommendations for you.</p>'; 
}

?>

</body> </html>
