        "serverSide": true,
        "ajax": {
            url : "data.php",

在Ajax的provided link选项卡上，您可以看到应该从服务器返回的数据格式。

因此，您需要修改脚本的输出：

$db = new ...
$statement  = $db->prepare("SELECT * FROM sehirler");
$statement->execute();
// to get 0-indexed array use `PDO::FETCH_NUM` mode
$results = $statement->fetchAll(PDO::FETCH_ASSOC);  

echo  json_encode(array(
    'data' => $results,
    // Maybe following fields are optional
    //"draw" => 1,
    //"recordsTotal" => 57,
    //"recordsFiltered" =>57,
));
