Accessing an array inside an array with a foreach loop

When I input my code I'm creating the correct output for the question, but I'm being told I'm not using the variable in my foreach loop. Where am I going wrong?

index.php 
<?php

$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

foreach ($flavors as $key => $item) {
  foreach($item as $key => $name){
    if($key == 'name'){

      echo $name . "\n";
    }

  }
}

?>

Although your code works it's overly complicated which probably throws the code checker off here. There's no need to use two foreach loops or check the key.

foreach($flavors as $item) {
    echo $item['name'];
}

<?php

$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
foreach($flavors as $flavor){
  if($flavor['in_stock']){
  echo $flavor['name'];
  }
}
?>
