Utf-8字符显示为ISO-8859-1

标签: php mysql utf-8 latin1

我在从db中插入/读取utf8内容时遇到了问题。我正在做的所有验证似乎都指出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

-sql:在进行插入之前我运行

SET names 'utf8';

-php:在进行插入操作之前,我使用 utf8_encode() mb_detect_encoding(),它会给我'UTF-8'。从db中检索内容之后,在将其发送给用户之前,mb_detect_encoding()也提供'UTF-8'

验证测试:

让我正确显示内容的唯一方法是将内容类型设置为拉丁语(如果我嗅到流量,我可以看到带有ISO-8859-1的内容类型标题):

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

此测试显示内容为拉丁文。我不明白为什么。 有人有任何想法吗?

感谢。

答案 0 :(得分:8)

好吧,我发现SET NAMES并不是那么好。在the docs ...

取得一个高峰

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';

给出一个镜头,看看是否适合你...

哦,请记住,所有UTF-8字符< = 127也是有效的ISO-8859-1字符。因此,如果您在流中只有字符< = 127,mb_detect_encoding将落在较高流行率字符集(默认情况下为“UTF-8”)...

答案 1 :(得分:1)

  1. 检索之前你在做什么?也是'SET NAMES utf8;'?否则,MySQL将静默转换为连接指示使用的字符集。
  2. 如果不是这样,SHOW FULL COLUMNS FROM table;会显示什么?拥有默认字符集的表并不意味着该列。即,这是有效的:
  3. CREATE TABLE test (
        `name` varchar(10) character set latin1
    ) CHARSET=utf8
