php - fatal error : Cannot use object of type stdClass as array in … on line 10

Question

我收到此错误消息:

Fatal error: Cannot use object of type stdClass as array

码:

if(isset($_POST['anmelden']))
{
    $email = $_POST['email'];
    $passwort = $_POST['passwort'];

    $statement = $pdo->prepare("SELECT * FROM hwvor_nutzer WHERE nutzer_email = :email");
    $result = $statement->execute(array('email' => $email));
    $user = $statement->fetch();

    if($user !== false && password_verify($passwort, $user['passwort'])) 
    {
        $_SESSION['userid'] = $user['id'];
        die('Login erfolgreich. Weiter zum <a href="nutzerberich.php">internen Bereich</a>');
    } 
    else 
    {
        $errorMessage = "E-Mail oder Passwort war ungültig<br>";
    }
}

Answer 1

您可能需要在获取数据之前检查$result的值，以防查询失败。我猜问题是由该行中的$user['passwort']引起的

if($user !== false && password_verify($passwort, $user['passwort']))

如果查询失败，则$user = $statement->fetch();不会将数组分配给$user，而是其他不能作为数组处理的东西。

此外，我相信

$result = $statement->execute(array('email' => $email));

应该更改为

$result = $statement->execute(array(':email' => $email));

请注意额外的:，它似乎是必需的，请查看examples on php.net。
