插入语句无法使用PDO的execute（array（））

Question

我正在尝试插入PDO Prepared语句并使其安全。我有一个可行的示例，当我在数组中添加第二个变量时，麻烦来自EXECUTE（）。 MySQL v5.5.60

$Table = "devices";
$Name = "Garage Door";

不起作用

function allResults($Table, $Name) {
    $pdo = Database::connect();
    $sql = $pdo->prepare("SELECT * FROM :table WHERE Name = :name ORDER BY ID DESC");
    $sql->execute([':name' => $Name, ':table' => $Table]);
    $data = $sql->fetch(PDO::FETCH_ASSOC);
    return $data;
}

不起作用

    function allResults($Table, $Name) {
    $pdo = Database::connect();
    $sql = $pdo->prepare("SELECT * FROM :table WHERE Name = :name ORDER BY ID DESC");
    $sql->execute(array(':name' => $Name, ':table' => $Table));
    $data = $sql->fetch(PDO::FETCH_ASSOC);
    return $data;
}

工作！

    function allResults($Table, $Name) {
    $pdo = Database::connect();
    $sql = $pdo->prepare("SELECT * FROM $Table WHERE Name = :name ORDER BY ID DESC");
    $sql->execute(array(':name' => $Name));
    $data = $sql->fetch(PDO::FETCH_ASSOC);
    return $data;
}

谢谢
