Convert string variables into JSON format in PHP

1  <? PHP 2  Header ("CONTENT-TYPE:TEXT/HTML;CHARSET=UTF-8;" ); 3  $arr Array (' Version_code ' =>2, ' version_name ' = ' updateversion ', ' versoin_desc ' + ' Update the map function ', ' versoin_path ' + ' http ://nnddkj.com/busiot/apk/busiot.apk '); 4  echo json_encode ($arr); 5  ? >

As the code above, the string variable is converted to JSON format output, but the output is as follows:

{"Version_code": 2, "Version_name": "Updateversion", "Versoin_desc": "\U66F4\U65B0\U4E86\U5730\U56FE\U529F\U80FD", " Versoin_path ":" http:\/\/nnddkj.com\/busiot\/apk\/busiot.apk "}

That is, all the Chinese in the array are missing after the Json_encode or appear \u2353.

The workaround is to use the UrlEncode () function to handle the following, before Json_encode, all the contents of the array are processed with UrlEncode (), and then converted to a JSON string with Json_encode (). Finally, I use UrlDecode () to turn the encoded Chinese back.

 1  <? php  2  header  ("content-type:text/html; Charset=utf-8; "  3   $arr  =  (' Version_code ' =>2, ' version_name ' = ' updateversion ', ' versoin_desc ' = urlencode  (' Updated map function '), ' Versoin_path ' =>urlencode  (' http://nnddkj.com/BusIot/APK/ busiot.apk '  4   UrlDecode  (Json_encode ( $arr   5 ? 

Output: {"Version_code": 2, "Version_name": "Updateversion", "Versoin_desc": "Updated map function", "Versoin_path": "/HTTP// nnddkj.com/busiot/apk/busiot.apk "}
