I cannot figure what to reference in order to add the number of likes by flavor to the view.

$popular ?

index.php
<?php

// INCLUDE MODEL FILE
require_once("flavors.php");



// CONTROLLER CODE
$flavors = get_flavors_by_likes(3);



// VIEW CODE
?><html>
<body>

    <h1>Ye Olde Ice Cream Shoppe</h1>

    <p>We sell amazing flavors of ice cream.</p>

    <h2>Most Popular Flavors</h2>

    <ul>
    <?php
        foreach ($flavors as $flavor) {
            echo "<li>" . $flavor["name"] .  "+" $number "</li>";
        }
    ?>
    </ul>

</body>
</html>
flavors.php
<?php

// This function returns all the flavors
// ordered by the date they have been added.
function get_all_flavors() {

    $flavors = array(
        array("name" => "Vanilla", "likes" => 312),
        array("name" => "Cookie Dough", "likes" => 976),
        array("name" => "Peppermint", "likes" => 12),        
        array("name" => "Cake Batter", "likes" => 598),
        array("name" => "Avocado Chocolate", "likes" => 6),        
        array("name" => "Jalapeno So Spicy", "likes" => 3),        
    );

    return $flavors;

}

// This function receives a number as an argument.
// It returns the newest flavors, the most recent
// flavor first. (The number of flavors returned

function get_recent_flavors($number) {

    $recent = array();
    $all = get_all_flavors();

    $total_flavors = count($all);
    $position = 0;

    foreach($all as $flavor) {
        $position = $position + 1;
        if ($total_flavors - $position < $number) {
            $recent[] = $flavor;
        }
    }

    return array_reverse($recent);

}

// This function receives a number as an argument.

    $total_flavors = count($all);
    $position = 0;

    $popular = $all;
    usort($popular, function($a, $b) {
        return $b['likes'] - $a['likes'];
    });

    return array_slice($popular, 0, $number);

}

?>

Hey Andrew,

The flavors array in flavors.php contains two keys: "name" and "likes". So you would need to reference the second key "likes" to get the number of likes per flavor.

In your index.php you edit which keys your code prints out.

    <?php
        foreach ($flavors as $flavor) {
            echo "<li>" . $flavor["name"] . " " . "+" . $flavor["likes"] .  "</li>";
        }
    ?>

Hope that helps,

Cheers
