converting unicode \u sequence (like \u041a) to normal utf-8 text in php
提问by Ekonoval
I have a string like this "\u041a\u043b\u0443\u0431 Test";
我有一个像这样的字符串“\u041a\u043b\u0443\u0431 Test”；
It was decoded by json_encode(), the original string was "Клуб Test" in russian. when I put it to js like
由json_encode()解码，原始字符串为俄文“Клуб Test”。当我把它放到 js 中时
alert("\u041a\u043b\u0443\u0431 Test");
alert("\u041a\u043b\u0443\u0431 测试");
I get correct displaying, like on the screen. So js in some way poperly decodes it to normal view. The question is how can I do the same thing in php, is there any built in method?
我得到了正确的显示，就像在屏幕上一样。因此，js 以某种方式将其解码为普通视图。问题是我如何在 php 中做同样的事情，有没有内置方法？
THE ANSWER IS:
$json_in = '{"testKey":"\u041a\u043b\u0443\u0431 Test"}';
$json_out = json_decode($json_in, true);
or
Convert "\u041a\u043b\u0443\u0431" to "Клуб"
and perform html_entity_decode($str, null, 'UTF-8');

You probably want HTML entities to print the characters:
您可能希望 HTML 实体打印字符：
- Ӓ for decimal code
- Ī for hex code
- Ӓ 十进制代码
- Ī 对于十六进制代码

While converting the data, use JSON_UNESCAPED_UNICODEas the options
转换数据时，JSON_UNESCAPED_UNICODE用作选项
echo json_encode($text, JSON_UNESCAPED_UNICODE);
