Right? As the question. Can I read the cookie set by js in php? And vice versa.

One exception is written on the server.CookieIf you addHttpOnly, ThenCookieCannot be accessed in JS.
But written in JSCookieCan be normally sent to the backend.

Yes. Js can usedocument.cookieAccess, php can be accessed through$_COOKIEGlobal variable access.

The server can be readable. It depends on whether the browser's cookie will be placed in the http request header, that is, in the request-header.Cookie:foo=barWhether the request header carries a cookie value depends on whether the domain and path of the cookie match the current request path.
The cookie set by PHP is also the information in the corresponding header, that is,Set-Cookie:foo=bar;path=/;domain=expampleAnd other information, js can not be read, it also depends on whether the path of the current page matches the domain and path of the Cookie set by PHP.

Js can be accessed through document. cookie, and php can be accessed through the $ _ COOKIE global variable.
