How to successfully pass data from Controller to View? – PHP

I have modelled and am now testing a Database for a PHP (CodeIgniter 4) web application. I made a function in my (products) Model that retrieves data from the DB and called that function in the controller.

    getBasicInfo(int $id): array
    {
        $db = $this->connectToDB();

        $query = $db->query('SELECT productName, productDescription, productType FROM konnektrix_db.products WHERE productID = $id LIMIT 1');
        $row = $query->getRow();
        return
            [   $row->productName,
                $row->productDescription,
                $row->productType
            ];
    }
}

class Home extends BaseController
{
    public function index()
    {
        $ProductModel = new Products();
        $data = $ProductModel->getBasicInfo(1);
        //$data['name'] = 'Yuna';

        return view('testing_view',$data);
    }
}

What i want is to be able to access that data ($data) from my view (testing_view) but when i do, it doesn’t recognise the variable. (refer to image for error)

<!DOCTYPE html>
<html lang="en">
<head>
    <title>Data testing view</title>
</head>
<body>

<h2>General product overview page</h2>

<h1><? $data; ?></h1>

</body>

Any idea on what i might be doing wrong?

I have looked at multiple sources on how to pass data from Controller to View in CI4, this is what they did unless i am missing something?

    When you pass an array to a view the array gets ‘exploded’ out.
    So $data['name'] becomes $name.

    So just search for variables with the array keys as the names.

    According to documentation you should call the variable using the escape function.

    Please try:

    Adding string identifiers to the array from getBasicInfo function.

    getBasicInfo(int $id): array
        {
            $db = $this->connectToDB();
    
            $query = $db->query('SELECT productName, productDescription, productType FROM konnektrix_db.products WHERE productID = $id LIMIT 1');
            $row = $query->getRow();
            return
                [   "name" => $row->productName,
                    "description" => $row->productDescription,
                    "type" => $row->productType
                ];
        }

    And then something like this in your view:

    <!DOCTYPE html>
<html lang="en">
<head>
    <title>Data testing view</title>
</head>
<body>

<h2>General product overview page</h2>

<h1><? esc($name); ?></h1>
<h1><? esc($description); ?></h1>
<h1><? esc($type); ?></h1>

</body>
