Can't pass this exercise

I'm struggling to pass that simple exercise, I all the time have the answer that the array is empty but the message isn't displayed.

I've tried to format my code two ways and It's still not working. What am I missing ???

Here are the codes I've tried.

<?php

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

This code works:

<?php

    $recommendations = array();

?><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>
</html>

I just put together these 2 lines:

<?php } ?>
<?php else {

I did:

<?php } else {

Your first $recommandations is not spelt the same as your last $recommendations.

<?php

    if(!empty($recommandations)){  // $recommendations IS NOT SPELLED CORRECTLY
        echo "<ul>";
        foreach($recommendations as $flavor) { // THIS ONE IS SPELLED CORRECTLY
            echo "<li>".$flavor."</li>";
         } 
        echo "</ul>";
    }
     else
    { 
     echo "<p>"."There are no flavor recommendations for you"."</p>";
    }
?>

Well spotted, but in fact, I had typed it correctly inside the exercise, I've just checked again. In case I had missed something else, I've also copied and pasted what you did, and It's still not working. Would you mind to try this on your side, to see if you can pass it ? (the first step is validated, that's at the second one that I get stuck).

Thank you for your help.

EDIT here is the other way I formatted my code, but doesn't work neither.

<?php

    $recommendations = array();

?>
<html>
<body>
<h1>Flavor Recommendations</h1>

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