A brief analysis of json transmission in php and js

Json is widely used in program data interaction due to its efficient performance. This article will give you a brief analysis of the encoding and decoding of json in php and js. To give you a reference, I hope it will be helpful to everyone.

php in

1)Encoding

$jsonStr = json_encode($array)

2)Decoding

$arr = json_decode($jsonStr)

 
Add parameters: JSON_UNESCAPED_UNICODE. 

Test environment: 
PHP Version 5.5.36
 js中
1. Encoding
var str = obj.toJSONString();//需要JSON解析器或工具类
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)；//
