code challenge "sku"?

Next, let’s move the flavors array into that function. This task has two steps. (1) Move the code that creates the flavors array from index.php into the get_all_flavors() function in flavors.php. (2) Add code at the end of the function so that it returns the array of flavors back to whatever code calls it. Thank you

index.php 
<?php

// ==== INCLUDE MODEL FILE ====
require_once('flavors.php');
flavors = array(
        "Jalapeno So Spicy",
        "Avocado Chocolate",
        "Peppermint",
        "Vanilla",
        "Cake Batter",
        "Cookie Dough"
    );
 ?>
<h1>Ye Olde Ice Cream Shoppe</h1>

<p>Here&rsquo;s a full list of our ice cream flavors.</p>

<ul>
<?php

    $list_html = "";
    foreach($flavors as $flavor) {
        $list_html = $list_html . "<li>";
        $list_html = $list_html . $flavor;
        $list_html = $list_html . "</li>";
    }
    echo $list_html;

?>
</ul>
flavors.php 
<?php

// MODEL FILE
function get_all_flavors(){
$flavors = array(
        "Jalapeno So Spicy",
        "Avocado Chocolate",
        "Peppermint",
        "Vanilla",
        "Cake Batter",
        "Cookie Dough"
    );

              foreach($flavors  as $flavors_id =>$flavors )
              {
                $flavors[$flavors_id]["sku"] = $flavors_id ;

              }
           return $flavors;       
}






?>

In your index.php you need to replace the array with:

$flavors = get_all_flavors()

The file should look like this :

// ==== INCLUDE MODEL FILE ====
require_once('flavors.php');

$flavors = get_all_flavors();

?>

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

<p>Here&rsquo;s a full list of our ice cream flavors.</p>

<ul>
<?php

    $list_html = "";
    foreach($flavors as $flavor) {
        $list_html = $list_html . "<li>";
        $list_html = $list_html . $flavor;
        $list_html = $list_html . "</li>";
    }
    echo $list_html;

?>
</ul>

And your flavors.php file like this:

// MODEL FILE
function get_all_flavors() {
$flavors = array(
        "Jalapeno So Spicy",
        "Avocado Chocolate",
        "Peppermint",
        "Vanilla",
        "Cake Batter",
        "Cookie Dough"
    );

  return $flavors;
}

?>

That is all. Hope it helps.
