PHP implements escape and unescape function code sharing in Javascript

This article mainly introduces PHP to implement escape and unescape function code sharing in Javascript. This article gives two implementations Version, friends in need can refer to it

This class is quite easy to use. What’s the purpose? PHP can use it to transfer GBK characters in JSON, such as Chinese, Japanese, Korean and Shenma’s Unicode.
