当我想将网站托管时遇到问题。我正在使用 nette，当我想连接时出现错误

PDO::__construct()：数据过早结束 (mysqlnd_wireprotocol.c:553)

我正在使用带有此数据库配置的 nette 框架：

dsn: 'mysql:host=dbhost;dbname=dbtable'
user: dbuser
password: dbpass

当我尝试经典连接时，它工作正常。我不知道该怎么做以及如何解决这个问题。

if($myslConnection = mysql_connect("dbhost", "dbuser", "dbpass")){
  echo("connected");
    mysql_select_db("dbtable",$myslConnection);
    $result = mysql_query("SELECT * FROM news", $myslConnection);

    while($resultItem = MySQL_Fetch_Row($result)){
         echo $resultItem[1]."<br>";
    }
}
else{
  exit("not connected");
}

编辑：错误我得到了什么
