Since PHP/5.4.0, there is an option called <code>JSON_UNESCAPED_UNICODE</code>. Check it out:
<a href="https://php.net/function.json-encode" rel="noreferrer">https://php.net/function.json-encode</a>
Therefore you should try:
<pre><code>json_encode( $text, JSON_UNESCAPED_UNICODE );
</code></pre>

blocks|key|103146|text|一种解决方案是首先对数据进行编码，然后在同一文件中对其进行解码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|103147|$string+=json_encode($input,+JSON_UNESCAPED_UNICODE)+;+
echo+$decoded+=+html_entity_decode(+$string+);|code-block|syntax|javascript|103148|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

One solution is to first encode data and then decode it in the same file:

<pre><code>$string =json_encode($input, JSON_UNESCAPED_UNICODE) ; 
echo $decoded = html_entity_decode( $string );
</code></pre>

The raw_json_encode() function <a href="https://stackoverflow.com/a/16498714/710788">above</a> did not solve me the problem (for some reason, the callback function raised an error on my PHP 5.2.5 server).

But this other solution did actually work.

Here is my combined solution for various PHP versions. 

In my company we are working with different servers with various PHP versions, so I had to find solution working for all. 

<pre><code>$phpVersion = substr(phpversion(), 0, 3)*1;

if($phpVersion &gt;= 5.4) {
 $encodedValue = json_encode($value, JSON_UNESCAPED_UNICODE);
} else {
 $encodedValue = preg_replace('/\\\\u([a-f0-9]{4})/e', "iconv('UCS-4LE','UTF-8',pack('V', hexdec('U$1')))", json_encode($value));
}
</code></pre>

I have a PHP script that deals with a wide variety of languages. Unfortunately, whenever I try to use <code>json_encode</code>, any Unicode output is converted to hexadecimal entities. Is this the expected behavior? Is there any way to convert the output to UTF-8 characters?

Here's an example of what I'm seeing:

INPUT

<pre><code>echo $text;
</code></pre>

OUTPUT

<pre><code>База данни грешка.
</code></pre>

INPUT

<pre><code>json_encode($text);
</code></pre>

OUTPUT

<pre><code>"\u0411\u0430\u0437\u0430 \u0434\u0430\u043d\u043d\u0438 \u0433\u0440\u0435\u0448\u043a\u0430."
</code></pre>

Why does the PHP json_encode function convert UTF-8 strings to hexadecimal entities?

服务器

我有一个处理各种语言的PHP脚本。不幸的是，每当我尝试使用json_encode时，任何Unicode输出都会转换为十六进制实体。这是预期的行为吗？有没有办法将输出转换成UTF-8字符？下面是我看到的一个例子：输入echo $text;输出База данни грешка.输入json_encode($text);输...
