Arrays

Where is my coding error? The code block below displays a list of flavors available at an ice cream store. In this code challenge, we'll modify this block to use an array so that it’s easier to add a new flavor. Change the line that creates the $flavor1 variable so that it instead creates an array called flavors. Give that flavors array one element with a value of "Chocolate". Important: The code you write in each task should be added to the code written in the previous task. Recheck Work Bummer! It looks like you haven't created an array named $flavors.

flavors.php

1 <?php 2

3 $flavors = array(); 4 $flavors = "Chocolate"; 5

6

7 ?> 8 <p>Welcome to Ye Olde Ice Cream Shoppe. We sell <?php echo "2"; ?> flavors of ice cream.</p> 9 <ul> 10 <li><?php echo $flavor1; ?></li> 11 <li><?php echo $flavor2; ?></li> 12 </ul>

put all the flavors in an array called $flavors, then you can use the php count function to get the number of items in the $flavors array. I stored the number of flavors in an array called $num_of_flavors.

To display the number of flavors, "echo" out the $num_of_flavors. Then to display each ice cream flavor, use a foreach loop.

<?php

$flavors = array("chocolate", "vanilla", "strawberry"); $num_of_flavors = count($flavors);

?>

Welcome to Ye Olde Ice Cream Shoppe. We sell <?php echo $num_of_flavors ?> flavors of ice cream.

<?php foreach ($flavors as $flavor) { echo $flavor; } ?>

The goal of the step is to create an array with the value of Chocolate.

With your;

            $flavors = array();

You create an array, but with your;

            $flavors = "Chocolate";

You're not adding it to the array. You're simple changing $flavors to a variable that equals "Chocolate".

You can add a value to an array like so;

            $flavors[] = "Chocolate";

Which is what I think you were original trying to accomplish. Hope this helps. :)
