Analysis of json_encode Chinese Encoding Problems in php

For example, if 'signature' is changed to '\ u80e5' after json_encode processing, the Chinese part of the final json is replaced with unicode encoding. What we need to solve is to convert the object to json and ensure that the Chinese character inside the object still appears in json as normal Chinese. Now it seems that json_encode alone cannot achieve the goal.
My solution: perform url encoding for the Chinese fields in the class first, then perform json encoding (jsonencode) for the object, and finally url Decoding (urldecode) json, that is, the final json. The Chinese in it is still the Chinese!
The test code is as follows:
Copy codeThe Code is as follows:
<? Php
Class myClass {
Public $ item1 = 1;
Public $ item2 = 'Chinese ';
Function to_json (){
// Url encoding to avoid converting Chinese to unicode using json_encode
$ This-> item2 = urlencode ($ this-> item2 );
$ Str_json = json_encode ($ this );
// Url Decoding. After converting json, all attributes are returned, so that the object attributes remain unchanged.
$ This-> item2 = urldecode ($ this-> item2 );
Return urldecode ($ str_json );
}
}
$ C = new myClass ();
Echo json_encode ($ c );
Echo '<br/> ';
Echo $ c-> to_json ();
Echo '<br/> ';
Echo json_encode ($ c );
Echo '<br/> ';
Echo json_encode ('authorization ');
?>

Program output result:
Copy codeThe Code is as follows:
{"Item1": 1, "item2": "\ u4e2d \ u6587 "}
{"Item1": 1, "item2": "Chinese "}
{"Item1": 1, "item2": "\ u4e2d \ u6587 "}
"\ U80e5"
