Question

我真的很想让PHP通过PDO与UTF-8角色一起玩MySQL。

我使用php --version得到以下内容：

PHP 5.3.6 (cli) (built: Apr 19 2011 13:21:12)
Copyright (c) 1997-2011 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2011 Zend Technologies

这是来自mysql cli的欢迎消息：

Server version: 5.1.57 Source distribution

我将此作为我的数据库连接代码：

try {
    $dbh = new PDO('mysql:host='.$server.';dbname='.$database.';charset=UTF8', $user, $password, array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES 'UTF8'"));
} catch (PDOException $e) {
    print "Error!: " . $e->getMessage() . "<br/>";
    die();
}

我的php代码插入MySQL：

$dbh->query("SET NAMES 'UTF8'"); 
$values = array(':idCode' => $idCode, ':name' => $name, ':address' => $address, ':postcode' => $postcode, ':tel' => $tel, ':website' => $website, ':disabled' => $disabled, ':disabledWC' => $disabledWC, ':description' => $description, ':location' => $location, ':type' => $type, ':status' => $status, ':image1name' => $image1name, ':image2name' => $image2name, ':image3name' => $image3name, ':image4name' => $image4name, ':image5name' => $image5name);
$preparedStatement = $dbh->prepare('UPDATE venues SET name = :name, address = :address, postcode = :postcode, tel = :tel, website = :website, disabled = :disabled, disabledWC = :disabledWC, description = :description, location = :location, type = :type, status = :status, date_modified = NOW(), image1name = :image1name, image2name = :image2name, image3name = :image3name, image4name = :image4name, image5name = :image5name WHERE idCode = :idCode');
$preparedStatement->execute($values);

我得到的问题是，即使我已经验证$ description确实包含UTF8编码的字节（在网上使用bin2hex和hex2UTF8工具），数据也不会通过连接以UTF-8的形式提交我最终在数据库中使用了“Générik”而不是“Générik”。

我尝试在执行之前调用“SET NAMES UTF8”，我已经输入：

[client]
default-character-set=utf8

[mysqld]
default-character-set=utf8

在我的my.cnf中，但似乎无法获得任何快乐。

有关如何使其发挥作用的任何提示或提示？

我应该添加 - 如果我在命令行MySQL客户端手动输入文本它工作正常，该列设置为采用UTF8编码。

按要求 - 创建表脚本：

| venues | CREATE TABLE `venues` (
  `idCode` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(512) DEFAULT NULL,
  `address` varchar(1024) DEFAULT NULL,
  `postcode` varchar(32) DEFAULT NULL,
  `tel` varchar(32) DEFAULT NULL,
  `website` varchar(1024) DEFAULT NULL,
  `disabled` tinyint(4) DEFAULT NULL,
  `disabledWC` tinyint(4) DEFAULT NULL,
  `description` varchar(4096) CHARACTER SET utf8 DEFAULT NULL,
  `status` tinyint(4) DEFAULT NULL,
  `location` varchar(32) DEFAULT NULL,
  `type` varchar(32) DEFAULT NULL,
  `date_modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  `image1name` varchar(255) DEFAULT NULL,
  `image2name` varchar(255) DEFAULT NULL,
  `image3name` varchar(255) DEFAULT NULL,
  `image4name` varchar(255) DEFAULT NULL,
  `image5name` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`idCode`)
) ENGINE=MyISAM AUTO_INCREMENT=129 DEFAULT CHARSET=latin1

并且结果是SELECT @@ character_set_database：

SELECT @@character_set_database
    -> ;
+--------------------------+
| @@character_set_database |
+--------------------------+
| utf8                     |
+--------------------------+
1 row in set (0.00 sec)

dumpParams的结果：

$ description的记录十六进制字节（和预期的字符串值）：

At King George V Playing Fields, Bar End.

Answer 1

  try {
      $dbh = new PDO(
          'mysql:host='.$server.';dbname='.$database, 
          $user, 
          $password,
          array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES 'UTF8'")
      );
      $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
  } catch (PDOException $e) {
      print "Error!: " . $e->getMessage() . "<br/>";
      die();
  }

在将数据放入数据库之前不要对数据进行编码，只需要纯粹的原始utf-8数据发送。应该够了。

问候。

Answer 2

对于单词Générik，您的“记录的十六进制字节”为0x47c3a96ec3a972696b。这确实是UTF-8编码的。您尝试验证存储数据的客户端几乎肯定在获取表内容之前设置了错误的字符集。

Answer 3

我遇到了同样的问题，我在this post的帮助下弄明白了。我正在向DB中提供完全有效的变音符号，但它存储了垃圾。

我基本上只是在我的connect / init密码之后添加了这个：array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES 'utf8'")，因此：

$this->db = new PDO($this->dsn, $this->username, $this->password, 
                    array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES 'utf8'"));

PHP，PDO，UTF8和MySQL不玩球
