Encoding and decoding of json in php and js

Encoding and decoding of json in php and js

php in

1) encoding

$jsonStr = json_encode($array)

2) decoding

$arr = json_decode($jsonStr)

echo json_encode("Chinese", JSON_UNESCAPED_UNICODE);

Just add the parameter: JSON_UNESCAPED_UNICODE.

Test environment:

PHP Version 5.5.36

js in

1. Encoding

var str = obj.toJSONString();//Requires JSON parser or tool class

2. Three types of decoding :

var jsonStr = ''[{"id":"1","name":"computer"}]";
　　1) var obj = eval(jsonStr); //兼容最好
　　2) var obj = jsonStr.parseJSON(); //这俩需要浏览器带JSON解析器。或者加一个json的工具类
　　3) var obj = JSON.parse(jsonStr)；//
