Summary:

1. Php uses its own functions to read php cookies. There is no obstacle and no decoding is required.
2. Js uses the cookie. js method to read js cookies. There is no obstacle and no decoding is required.
3. Js reads php Chinese cookies and requires "decodeURIComponent (escape (php_cn_ck)" function processing.
4. Php needs to perform the "unescape ()" function to read the Chinese cookies of js.

Cookie. js

Var Cookies = {};/***** set Cookies */Cookies. set = function (name, value) {var argv = arguments; var argc = arguments. length; var expires = (argc> 2 )?
