Question

如何使用预先准备的语句获取mysqli_fetch_array？我试过fetch_assoc()但是我总是收到一个错误，告诉我fetch_assoc()没有定义。我如何使其发挥作用？

$query = "SELECT * FROM users WHERE 
            username = ? AND 
            pass = ? LIMIT 1";

$stmt = $_SESSION['connessione']->prepare($query);
$stmt->bind_param('ss', $username, $password);
$stmt->execute();
$stmt->store_result();

if($stmt->num_rows == 1){
    $row = $stmt->fetch_assoc();
    // originally it was like this $row = mysqli_fetch_array($result);
    // where $result was the query result
    $this->login_iduser = $row['id'];
    $this->login_profile_pic = $row['pic'];
    $this->login_privileges = $row['admin'];
    return TRUE;
}
return FALSE;

如您所见，我需要找到$row数组。

您必须安装MySQLND才能执行此操作。 mysqli准备好的语句本身不会产生mysqli_result个对象。您需要使用get_result

$stmt->execute();
$result = $stmt->get_result();
if($result->num_rows == 1){
    $row = $result->fetch_assoc();

带有预处理语句的mysqli_fetch_array
