Php / json：decode utf8？ [英] Php/json: decode utf8?

问题描述

我存储一个json字符串，其中包含一些（中文？）字符在mysql数据库。
数据库中的示例：

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

在我的PHP页面上我只是做一个json_decode从mysql接收， t显示正确，它显示像½±è§

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§�"

我试图在我的开始执行SET NAMES'utf8'文件，没有改变任何东西。
我的网页上已经有以下标题：

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" />

当然所有的php文件都是用UTF-8编码的。

And of course all my php files are encoded in UTF-8.

你有什么想法如何很好地显示这些\uXXXX字符？

Do you have any idea how to display these "\uXXXX" characters nicely?

推荐答案

Unicode不是UTF-8！

Unicode is not UTF-8!

$ echo -en '\x8b\xf1\x60\xd1\x00\n' | iconv -f unicodebig -t utf-8
诱惑

这是一个奇怪的编码你有。我猜每个字符的正常文本是一个字节长（US-ASCII）？然后你必须提取\u ....序列，转换序列在一个两个字节字符，并转换该字符与 iconv（unicodebig，utf-8，$字符）更改为UTF-8字符（请参见 iconv < a>在PHP文档中）。这在我身边有效：

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:

$in = "normal.text.\u8bf1\u60d1.rest.of.text";

function ewchar_to_utf8($matches) {
    $ewchar = $matches[1];
    $binwchar = hexdec($ewchar);
    $wchar = chr(($binwchar >> 8) & 0xFF) . chr(($binwchar) & 0xFF);
    return iconv("unicodebig", "utf-8", $wchar);
}

function special_unicode_to_utf8($str) {
    return preg_replace_callback("/\\\u([[:xdigit:]]{4})/i", "ewchar_to_utf8", $str);
}

echo special_unicode_to_utf8($in);

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。

Otherwise we need more Information on how your string in the database is encoded.
