Answer 1

Use

<?php
$flavors = array(
array("name" => "CD" , "in_stock" => true),
array("name" => "V"  , "in_stock" => true),
array("name" => "S"  , "in_stock" => false));

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

instead

foreach($flavors as $flavor => value){

You are using multimentionals arrays, to use your aproach (=> value):

foreach ($flavors as $flavor => $value) {
if ($value['in_stock'] == true) {
    echo $value['name']."
";
 }
}
