PHP/json:解码utf8?
我在 mysql 数据库中存储了一个包含一些(中文?)字符的 json 字符串。 数据库中内容的示例:
normal.text.\u8bf1\u60d1.rest.of.text
在我的 PHP 页面上,我只是对从 mysql 收到的内容进行了 json_decode,但它显示不正确,它显示了诸如“½±è§�”之类的内容,
我尝试执行“ SET NAMES 'utf8'”查询位于我的文件开头,没有更改任何内容。 我的网页上已经有以下标头:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
当然,我所有的 php 文件都以 UTF-8 编码。
你知道如何很好地显示这些“\uXXXX”字符吗?
I store a json string that contains some (chinese ?) characters in a mysql database.
Example of what's in the database:
normal.text.\u8bf1\u60d1.rest.of.text
On my PHP page I just do a json_decode of what I receive from mysql, but it doesn't display right, it shows things like "½±è§�"
I've tried to execute the "SET NAMES 'utf8'" query at the beginning of my file, didn't change anything.
I already have the following header on my webpage:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
And of course all my php files are encoded in UTF-8.
Do you have any idea how to display these "\uXXXX" characters nicely?

这似乎对我来说工作得很好,在 Ubuntu 11.04 上使用 PHP 5.3.5:
输出:
This seems to work fine for me, with PHP 5.3.5 on Ubuntu 11.04:
Outputs this:
Unicode 不是 UTF-8!
这是一个奇怪的“编码”。我猜普通文本的每个字符都是“一个字节”长(US-ASCII)?然后,您必须提取 \u.... 序列,将序列转换为“两字节”字符,并使用 iconv("unicodebig", "utf-8", $character) 转换该字符 转换为 UTF-8 字符(请参阅 PHP 文档中的 iconv )。这对我来说很有效:
否则我们需要更多关于数据库中的字符串如何编码的信息。
Unicode is not UTF-8!
This is a strange "encoding" you have. I guess each character of the normal text is "one byte" long (US-ASCII)? Then you have to extract the \u.... sequences, convert the sequence in a "two byte" character and convert that character with
iconv("unicodebig", "utf-8", $character)
to an UTF-8 character (see iconv in the PHP-documentation). This worked on my side:Otherwise we need more Information on how your string in the database is encoded.
这是一个转移注意力的事情。如果您通过 http 提供页面,并且响应包含
Content-Type
标头,则元标记将被忽略。默认情况下,如果您没有明确设置,PHP 将设置这样的标头。默认设置为iso-8859-1
。尝试使用这一行:
That's a red herring. If you serve your page over http, and the response contains a
Content-Type
header, then the meta tag will be ignored. By default, PHP will set such a header, if you don't do it explicitly. And the default is set asiso-8859-1
.Try with this line:
