我正在尝试在我的数据库表中插入一些数据，但是当我尝试在货币列中保存欧元符号时，我得到了这个例外：
PDOException: SQLSTATE[HY000]: General error: 1366
Incorrect string value: '\x80' for column 'currency' at row 1
如果我不使用任何符号，它可以正常工作。抛出异常并且数据在数据库表中正确写入。
这就是我正在使用的技术堆栈：
我试图谷歌解决方案，但没有任何方法可以帮助我：
但没有任何帮助...
这是我的表的创建脚本，我现在正在使用：
CREATE TABLE `cars` (
`car_id` int(11) NOT NULL AUTO_INCREMENT,
`brand` varchar(191) COLLATE utf8mb4_unicode_ci NOT NULL,
`model` varchar(191) COLLATE utf8mb4_unicode_ci NOT NULL,
`car_trim` varchar(191) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`model_year` int(11) DEFAULT NULL,
`car_condition` varchar(191) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`car_type` varchar(191) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`currency` varchar(191) COLLATE utf8mb4_unicode_ci DEFAULT NULL, <-- Where the € should be
PRIMARY KEY (`xy`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8mb4
COLLATE=utf8mb4_unicode_ci;
我的PDO连接如下所示：
if(!isset(self::$connection)) {
try {
self::$connection = new PDO('mysql:host='.self::$config['host'].
';dbname='.self::$config['dbname'].
';port='.self::$config['port'].
';charset='.self::$config['charset'], //utf8mb4
self::$config['username'],
self::$config['password']
);
self::$connection->setAttribute( PDO::ATTR_ERRMODE,
PDO::ERRMODE_EXCEPTION );
} catch (PDOException $e) {
self::$logger->LogError('Connection.php: ' . $e->getMessage());
echo $e->getMessage();
self::$connection->rollBack();
$this->closeConnection();
}
}
带有insert语句的PHP代码：
$db = new Db();

我有一个解决方案，我不知道它是否完美，但至少它工作正常！
我在打开数据库连接后添加了这行代码：
$pStatement = $db->getConnection()->query("SET CHARACTER SET utf8");
在此查询之后，我可以插入我想要的内容（例如，ÄÜÖö䧀％$'＃etc ...），它最终会正确存储在我的表格中。
好的，谢谢你试图帮助我。我希望这个解决方案可以帮助其他有同样问题的人。
祝大家新年快乐。 :-)
