Question

我有一个Wordpress网站随机显示如下错误：

WordPress database error: [Incorrect string value: '\xF0\x9F\x92\x97\xF0\x9F...' for    column 'option_value' at row 1] UPDATE `wp_options` SET `option_value` = 'a:95:{

这是占位符网站;使用PhpMyAdmin将数据从现有实时导出到.sql文件中。我怀疑有某种字符编码问题？我已经导出了任何'默认可能和UTF8一样。在导入的数据库中，我已经尝试将字符编码和整理作为UTF8（它当前）以及'Latin1 ISO8899西欧'和'utf_general_ci'分别作为编码和整理，但没有运气。

我注意到在一段时间后我去网站时会发生错误。

我该怎么办？谢谢！

Answer 1

我最近写过a detailed guide on how to switch from MySQL’s utf8 to utf8mb4。如果你按照那里的步骤，一切都应该正常工作。以下是该流程中每个步骤的直接链接：

Answer 2

问题可能是编码不匹配。 utf8可以存储最多3个字节的字符，utf8mb4可以存储最多4个字节的字符。我猜你的.sql文件中的数据包含utf8不支持的稀有符号。尝试重新导入.sql文件，但将编码设置为utf8mb4。我不久前在Joomla遇到了同样的问题。

Answer 3

I encountered the same problem today.
After tried many times, I found out the reason and fix it at last.
For applications that store data using the default MySQL character set and collation (latin1, latin1_swedish_ci), so you need to specify the character set and collation to utf8/utf8_general_ci when your create your database or table.
e.g.:
        $sql = "CREATE TABLE " . $table_name . " (
        id mediumint(9) NOT NULL AUTO_INCREMENT,
        bookname varchar(128) NOT NULL,
        author varchar(64) NOT NULL,
        PRIMARY KEY  (id),
        KEY (bookname)
        )CHARACTER SET utf8 COLLATE utf8_general_ci;";
