尝试以下翻译代码部分：
try {
$sql = 'UPDATE kunder SET ' .
'fname=:fname,' .
'ename=:ename,' .
'user=:user ' .
'WHERE id = :id';
$stmt = $dbconn->prepare($sql);
$data = array(
'fname' => $fname,
'ename' => $ename,
'user' => $user,
'id' => $_SESSION["user_id"],
);
$stmt->execute($data);
} catch (PDOException $e) {
echo $sql . "<br>" . $e->getMessage();
}
希望这对你有所帮助。如果你需要进一步的翻译或有其他问题，请随时提出。
