PDO连接mysql8.0报PDO::__construct(): Server sent charset (255) unknown to the client. Please, report to the developers错误

安装mysql8.0之后，尝试使用php连接mysql，总是报PDO::__construct(): Server sent charset (255) unknown to the client. Please, report to the developers错误，网上找了很多资料，然而都没有多大用处。

查找了mysql官方说明文档才知道原来M8.0已经已经把默认字符集升级成ut8mb4了，于是找到my.cnf文件，修改如下：

 1 [client]

  2 port = 3306

  3 socket = /tmp/mysql.sock

  4 default-character-set = utf8

  5

  6 [mysql]

  7 prompt="MySQL [\d]> "

  8 no-auto-rehash

  9 default-character-set = utf8

 10

 11 [mysqld]

 12 port = 3306

 13 socket = /tmp/mysql.sock

 14 default_authentication_plugin = mysql_native_password

 15 collation-server = utf8_unicode_ci

 16

 17 basedir = /usr/local/mysql

 18 datadir = /data/mysql

 19 pid-file = /data/mysql/mysql.pid

 20 user = mysql

 2 bind-address = 0.0.0.0

 22 server-id = 1

 23

 24 init-connect = 'SET NAMES utf8'

 25 character-set-server = utf8

然后使用PDO连接mysql

$db = array(

    'host' => 'your host',         //设置服务器地址

    'port' => '3306',              //设端口

    'dbname' => 'your db name',    //设置数据库名

    'username' => 'your name',     //设置账号

    'password' => 'your pwd',      //设置密码

    'charset' => 'utf8',           //设置编码格式

    'dsn' => 'mysql:host=your host;dbname=your db name;port=3306;charset=utf8',

);  

//连接

$options = array(

    PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION, 　　　　//默认是PDO::ERRMODE_SILENT, 0, (忽略错误模式)

    PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,   // 默认是PDO::FETCH_BOTH, 4

);  

try{

    $pdo = new PDO($db['dsn'], $db['username'], $db['password'], $options);

    var_dump($pdo);

}catch(PDOException $e){

    die('数据库连接失败:' . $e->getMessage());

}

结果如下：

object(PDO)#1 (0) { }
