Why: $products[$product_id]["sku"] = $product_id;

Inside the {} brackets of the foreach loop in this video, can someone explain

Why it is: $products[$product_id]["sku"] = $product_id;

Instead of: $product[$product_id]["sku"] = $product_id;

Hey Sam, there is no link to this video. Are you able to paste some code in?

Hey Sam, you would use $products because you are adding a new key-value pair to the parent object, where $product is the value of $product_id and most likely a string.

// so would look something like:
$products["12345678"]["sku"] = "12345678";
foreach ($products as $product_id => $product) {
        $products[$product_id]["sku"] = $product_id;
    return $products;
