php - 将 scandic 字母插入数据库时​​出错

Question

我正在尝试将包含 scandic 字母的网址插入到我的数据库中，例如:

ÄÖäöÅå

我正在使用:

• Opensuse 13.2 64 位 Linux 和 MariaDB。
• MySQL服务器版本:5.5.44-MariaDB openSUSE包
• PHP 版本为 5.4.20

当我尝试插入时，我收到此错误消息:

Incorrect string value: '\xC4HK\xD6.

此查询确认字符集和排序规则设置正确:

if (mysql_query("SET NAMES utf8mb4 COLLATE utf8mb4_unicode_ci")) {
    echo "Character set OK !";
}

我的 MySQL 查询适用于除包含 scandic 字母的 URL 之外的所有内容:

if (mysql_query("INSERT INTO `table` (`address`) VALUES ('$URL')")){
    $insertCount++;
    echo "<br> insertcount = ".$insertCount."<br>";
} else {
    echo "MySQLerror = ".mysql_error()."<br>"; // Show MySQLerror

这是来自 MariaDB 的 MySQL 信息，显示所有内容都设置为 utf8mb4 :

MariaDB [(none)]> SHOW VARIABLES WHERE Variable_name LIKE 'character\_set\_%' OR Variable_name LIKE 'collation%';

如何正确插入 scandic 字母？

@Monty:这些是我的数据库设置:

MariaDB [(none)]> show variables like '%colla%';
+----------------------+--------------------+

@Rick James:这是我得到的:


MariaDB [db]> SHOW CREATE TABLE table;

| Table | Create Table |

Answer 1

试试这个

验证存储数据的表是否具有 utf8 字符集:

SELECT
  `tables`.`TABLE_NAME`,
  `collations`.`character_set_name`
FROM
  `information_schema`.`TABLES` AS `tables`,
  `information_schema`.`COLLATION_CHARACTER_SET_APPLICABILITY` AS `collations`
WHERE
  `tables`.`table_schema` = DATABASE()
  AND `collations`.`collation_name` = `tables`.`table_collation`
;

检查你的数据库设置:

show variables like '%colla%';
show variables like '%charac%';

把utf-8改成utf8_general_ci

ALTER TABLE tablename CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci;
