простой html dom, ошибка соскоба Примечание: попытка получить свойство необъекта в C: \ xampp \ htdocs \ scraper \ au_div_puller.php в строке 60

Я написал скребок в php, используя простой HTML Dom.

Проблема в том, что он возвращает результаты, но выдает ошибку

Может кто-нибудь указать мне в правильном направлении, как это исправить, пожалуйста
Ошибка:

Большое спасибо

Это готовое заявление, которое я мог бы использовать, которое я скопировал с сайта обучения

// prepare and bind
$stmt = $conn->prepare("INSERT INTO MyGuests (firstname, lastname, email) VALUES (?, ?, ?)");
$stmt->bind_param("sss", $firstname, $lastname, $email);

// set parameters and execute
$firstname = "John";
$lastname = "Doe";
$email = "[email protected]";
$stmt->execute();

$firstname = "Mary";
$lastname = "Moe";
$email = "[email protected]";
$stmt->execute();

$firstname = "Julie";
$lastname = "Dooley";
$email = "[email protected]";
$stmt->execute();

echo "New records created successfully";

$stmt->close();
$conn->close();
