PHP PHP Arrays and Control Structures PHP Loops Looping with PHP

Getting correct answer, but states "You are not using the variable you defined in the foreach loop."

I don't understand why this question is incorrect. The variable I created in the two foreach loops all seem used.


$flavors = array();
$flavors[] = array("name" => "Cookie Dough",      "in_stock" => true);
$flavors[] = array("name" => "Vanilla",           "in_stock" => false);
$flavors[] = array("name" => "Avocado Chocolate", "in_stock" => false);
$flavors[] = array("name" => "Bacon Me Crazy",    "in_stock" => true);
$flavors[] = array("name" => "Strawberry",        "in_stock" => false);

//add your code below this line
$filter = array();
foreach ($flavors as $key => $item) {
    if ($item['in_stock'] == true)  {
    $filter[$key] = $item; 
foreach ($filter as $id => $value) {
    echo $flavors[$id]['name'] . '<br />';

You overthink it. You don't need a new array to store all of the flavours that are available or creating another foreach loop to display them. You just need a single foreach loop and echo the flavours that are available. This is all you need:


foreach ($flavors as $flavor) {
  if ($flavor["in_stock"] === true) {
    echo $flavor;
