Cyrillic characters in PHP's json_encode
提问by AquilaX
I'm trying to encode Cyrillic UTF-8 array to JSON string using php's function json_encode. The sample code looks like this:
我正在尝试使用 php 的函数 json_encode 将 Cyrillic UTF-8 数组编码为 JSON 字符串。示例代码如下所示：
<?php
$arr = array(
'едно' => 'първи',
'две' => 'втори'
);
$str = json_encode($arr);
echo $str;
?>
It works fine but the result of the script is represented as:
它工作正常，但脚本的结果表示为：
{"\u0435\u0434\u043d\u043e":"\u043f\u044a\u0440\u0432\u0438","\u0434\u0432\u0435":"\u0432\u0442\u043e\u0440\u0438"}
which makes 6 characters for each Cyrillic character. Is there a way to get the original characters for key/value pairs instead of encoded ones?
这为每个西里尔字符生成 6 个字符。有没有办法获取键/值对的原始字符而不是编码的字符？

Can't you use JSON_UNESCAPED_UNICODEconstant here?
你不能在这里使用JSON_UNESCAPED_UNICODE常量吗？

I found this in the code of Zend framework:
我在 Zend 框架的代码中发现了这一点：
http://framework.zend.com/svn/framework/standard/trunk/library/Zend/Json/Decoder.php
http://framework.zend.com/svn/framework/standard/trunk/library/Zend/Json/Decoder.php
Take a look at the function decodeUnicodeString ( line 474 ):
看看函数 decodeUnicodeString （第 474 行）：
/**
* Decode Unicode Characters from \u0000 ASCII syntax.
*
* This algorithm was originally developed for the
* Solar Framework by Paul M. Jones
*
* @link http://solarphp.com/
* @link http://svn.solarphp.com/core/trunk/Solar/Json.php
* @param string $value
* @return string
*/
public static function decodeUnicodeString($chrs)
It's static, and you can easily extract it - just replace the line:
它是静态的，您可以轻松提取它 - 只需替换该行：
490: $utf8 .= self::_utf162utf8($utf16);
with:
和：
490: $utf8 .= mb_convert_encoding($utf16, 'UTF-8', 'UTF-16');
Not an ideal solution, but did the job for me :o)
不是理想的解决方案，但为我完成了工作:o)

$str = json_encode($arr, JSON_UNESCAPED_UNICODE);
The use of this solution worked for me with the Latin and the Cyrillic alphabet, with PHP 5.5
这个解决方案的使用对我来说适用于拉丁字母和西里尔字母，以及 PHP 5.5

This is a realy old question, but I don't think it was answered correctly.
这是一个非常古老的问题，但我认为没有正确回答。
use something like this:
使用这样的东西：
print json_encode($array, JSON_UNESCAPED_UNICODE);

It looks like PHP's built in json_encodeonly works with UTF-8, and no other bells and whistles for tweaking how it works with respect to encoding.
看起来 PHP 的内置json_encode只适用于UTF-8，没有其他花里胡哨的东西来调整它在编码方面的工作方式。
I found A completely fair and balanced comparison of php json librarieson Google. It might help you. You might try another library based on the tables here, if possible. There are additional PHP libraries listed at json.orgthat you can experiment with.
我在 Google 上找到了一个完全公平和平衡的 php json 库比较。它可能会帮助你。如果可能，您可以根据此处的表格尝试另一个库。json.org上列出了其他 PHP 库，您可以进行试验。

With nasty bypass in JSON.php, rows 298..
在 JSON.php 中有讨厌的绕过，第 298 行..
$char = pack('C*', $ord_var_c, ord($var{$c + 1}));
$c += 1;
//$utf16 = $this->utf82utf16($char);
//$ascii .= sprintf('\u%04s', bin2hex($utf16));
$ascii .= $char;
Thanks!
谢谢！

I was dealing the same problem for Turkish ... indeed we don't have to do anything browsers automatically converts them in JS code blocks. So the easiest way of getting them decoded is getting them through javascript. (Ajax etc...)
我正在为土耳其语处理同样的问题……事实上，我们不必做任何事情，浏览器会自动将它们转换为 JS 代码块。因此，解码它们的最简单方法是通过 javascript 获取它们。（阿贾克斯等...）
