Consider the following table data and PHP code.
What is the outcome?
Table data (table name "users" with primary key "id"):
PHP code (assume the PDO connection is correctly established):
$dsn = ‘mysql:host=localhost;dbname=exam’;
$user= ‘username’;
$pass=’********’;
$pdo = new PDO{$dsn, $user, $pass);
$cmd ="SELECT* FROM users WHERE id= :id";
$stmt = $pdo->prepare($cmd);
$id = 3;
$stmt->bindParam(‘id’, $id);
$stmt->execute();
$stmt->bindColumn{3, $result);
$row= $stmt->fetch(PDO::FETCH_BOUND);
A . The database will return no rows.
B . The value of $row will be an array.
C . The value of $result will be empty.
