PHP Enhancing a Simple PHP Application Refactoring the Codebase Separating Concerns: Models

stage 4 challenge 2

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.

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

// MODEL FILE

my Code (index.php):

<?php

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

?>

Ye Olde Ice Cream Shoppe

Here’s a full list of our ice cream flavors.

<?php get_all_flavors($flavors); *this is where I am attempting to return the value of the array* $list_html = ""; foreach($flavors as $flavor) { $list_html = $list_html . "
"; $list_html = $list_html . $flavor; $list_html = $list_html . "
"; } echo $list_html;

?>

Delete the flavors array inside the index.php file. Inside your flavors.php file, when you call your function, do not put the parameter of flavors. When you created your function, it didn't include any parameters so you don't put any when you call it. You can also delete your foreach loop because it just adds the arrays one by one when the challenge is asking you to print the entire array from the function call (which you already did).
