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("中文", JSON_UNESCAPED_UNICODE);

Add parameters: JSON_UNESCAPED_UNICODE.

Test environment:

PHP Version 5.5.36

in js

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); //The best compatibility
　2) var obj = jsonStr.parseJSON(); //These two require a browser with a JSON parser. Or add a json tool class
　3) var obj = JSON.parse(jsonStr); //
