Challenge #3

Let's make sure that foreach loop executes correctly if the $recommendations array is NOT empty. Add one element to the $recommendations array with a value of 'Avocado Chocolate'.

I've used:

"<?php array_unshift($recommendations,"Avocado Chocolate"); ?>"

$recommendations = array() . "Avocado Chocolate";

It won't take them....

your first one should have worked. just make sure you have it inside the first php block in the file and under the code that initialized the recommendations array

<?php

    $recommendations = array();
    array_unshift($recommendations,"Avocado Chocolate"); 
?>

you did not do task 2 correctly and thats causing task 3 not to pass. You were supposed to use an else block and display that there are no recommendations paragraph within that else block. remove that exit statement and add an else block

<?php

    $recommendations = array();
    array_unshift($recommendations,"Avocado Chocolate");


?><html>
<body>

    <h1>Flavor Recommendations</h1>
<?php if(!empty($recommendations)) {?>
    <ul>
        <?php foreach($recommendations as $flavor) { ?>
            <li><?php echo $flavor; ?></li>
        <?php } ?>
    </ul>
  <?php }  else {

      echo "<p>There are no flavor recommendations for you.</p>";

    } ?>


</body>

Still said no.
