Sql; error bedeutung

[liebewinter]

Danke für deine Antwort !

lose nur diese Zeile oder das Ganze,

try {
           
               $sql = new PDO("id, name, email, message, datetime, ip");

               $id = $hope;

               $sql = "DELETE FROM mela WHERE id = :id";

               $statement = $connection->prepare($sql);
               $statement->bindValue(':id', $id);
               $statement->execute();

               $success = "User successfully deleted";
           } catch(PDOException $error) {
              var_dump($error->getMessage());
         }
