unicode to Chinese

Today I encountered a problem of converting unicode characters back to Chinese. After searching, it seems that PHP does not have a special built-in function for this.

After searching the Internet, some netizens posted their own encapsulated php tools. The functions can be realized, but it is a bit troublesome to introduce a method to solve this problem.

Later I thought that after we json_encode the Chinese string, we will get the Chinese unicode string. Can we use json_decode to solve this problem?

The answer is yes, but what I mean is that outside the unicode string, must be wrapped in a layer of double quotes

<span style="color:#330033;"><?php
$str = &#39;\u9a6c\u4e1c&#39;;
echo json_decode(&#39;"&#39; . $str . &#39;"&#39;);

//马东</span>

The above has introduced the conversion of unicode to Chinese, including aspects of it. I hope it will be helpful to friends who are interested in PHP tutorials.
