关于 UTF-8 字符，我真的很努力地试图让 PHP 通过 PDO 与 MySQL 一起玩。

我使用 php --version 得到以下信息:

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();
}

还有我要插入 MySQL 的 php 代码:

$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);

我遇到的问题是，即使我已经验证 $description 确实包含 UTF8 编码字节(在网络上使用 bin2hex 和 hex2UTF8 工具)，数据也不会通过连接作为 UTF-8 提交我最终在数据库中得到了“Générik”而不是“Générik”。

我已经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中却似乎无法获得任何乐趣。

关于如何让它工作的任何提示或技巧？

我应该补充 - 如果我在命令行 MySQL 客户端中手动输入文本，它工作正常，该列设置为采用 UTF8 编码。

根据要求 - 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

以及 SELECT @@character_set_database 的结果:

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

以及dumpParams的结果:

记录 $description 的十六进制字节(和预期的字符串值):

最佳答案

  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其进行编码，只发送纯原始的 utf-8 数据。应该够了。

问候。
