UTF-8 字符显示为 ISO-8859-1

我在从数据库插入/读取 utf8 内容时遇到问题。我所做的所有验证似乎都表明我的数据库中的内容应该是 utf8 编码的事实，但它似乎是拉丁编码的。数据最初是从 CLI 的 PHP 脚本导入的。

配置：

Zend Framework Version: 1.10.5
mysql-server-5.0:   5.0.51a-3ubuntu5.7
php5-mysql:     5.2.4-2ubuntu5.10
apache2:        2.2.8-1ubuntu0.16
libapache2-mod-php5:    5.2.4-2ubuntu5.10

验证：

-mysql:

-sql：在进行插入之前我运行

SET names 'utf8';

-php：在进行插入之前我使用utf8_encode() and mb_detect_encoding()这给了我“UTF-8”。从数据库检索内容之后并将其发送给用户之前 mb_detect_encoding() 也会给出“UTF-8”

验证测试：

让内容正确显示的唯一方法是将内容类型设置为拉丁语（如果我嗅探流量，我可以看到带有 ISO-8859-1 的内容类型标头）：

ini_set('default_charset', 'ISO-8859-1');

此测试显示内容显示为拉丁文。我不明白为什么。 有人有什么想法吗？

Thanks.

嗯，我发现了SET NAMES并不是真的那么好。达到峰值the docs http://dev.mysql.com/doc/refman/5.0/en/charset-connection.html...

我通常做的是执行 4 个查询：

SET CHARACTER SET 'UTF8';
SET character_set_database = 'UTF8';
SET character_set_connection = 'UTF8';
SET character_set_server = 'UTF8';

尝试一下，看看是否适合您......

哦，请记住，所有 mb_detect_encoding将落在较高流行的字符集（默认情况下为“UTF-8”）...
