fetchAll only fetches one row from two joined tables

I have a join of two tables. Actually the code and the fetching worked fine before I inserted :

$id=isset($_GET['id']) ? $_GET['id'] : die('ERROR: Record ID not found.');

and

WHERE id = ? LIMIT 0,1";

But now it only fetches the first row even though there are two:

  $id=isset($_GET['id']) ? $_GET['id'] : die('ERROR: Record ID not found.');

  try {

  $connection = DbConnect();

  $sql = "SELECT * FROM product
LEFT JOIN brand
ON product.id = brand.product_id
WHERE id = ? LIMIT 0,1";

  $statement = $connection->prepare($sql);
  $statement->bindParam(1, $id);
  $statement->execute();

  $result = $statement->fetchAll(PDO::FETCH_ASSOC);

} catch(PDOException $error) {

I used fetchAll and a foreach loop so I just don’t see why it is only fetching the first row. Maybe someone can help, thank you!

Answer

Your error here:

 $sql = "SELECT * FROM product LEFT JOIN brand ON product.id = brand.product_id WHERE id = ? LIMIT 0,1";

You using limit context, which it return back one row. Try you change limit 0,1 to limit 10.
