Utf-8字符显示为ISO-8859-1

Question

从插入/读取数据库中的utf8内容时遇到问题.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.最初从CLI从PHP脚本导入数据.

-sql:在进行插入之前我运行了

SET names 'utf8';

-php:在进行插入之前,我使用utf8_encode()和mb_detect_encoding(),这给了我'UTF-8'.从db中检索内容并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');

此测试显示内容以拉丁语形式出现.我不明白为什么.有人有任何想法吗？

谢谢.

好吧,我发现那SET NAMES并不是那么好.在文档中巅峰......

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';

试一试,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<= 127的字符,mb_detect_encoding则会落在较高流行率的字符集(默认情况下为"UTF-8")...
