JavaScript is a script that runs on the client, so it is generally not possible to set the session because the session is running on the server side.The cookie is run on the client, so you can use JS to set the cookie.Suppose there is a case, in a use case process, a page jumps to page B, if the a page with the variable temp Save the value of a variable, in the B page, also need to use JS to reference the variable value of temp, for JS in the global variable or static variable life cycle is limi

Today, the PHP cookie must be refreshed and the problem can be resolved as follows:PHP cookie setting function takes effect immediately, supports arrayfunction Cookie ($var, $value = ', $time = 0, $path = ', $domain = ', $s = false){$_cookie[$var] = $value;if (Is_array ($value)) {foreach ($value as $k = = $v) {Setcookie ($var. ' ['. $k. '] ', $v, $time, $path, $domain, $s);}} else {Setcookie ($var, $value, $time, $path, $domain, $s);}}This will not be refreshed, directly can get the value of the

Cookie Creation
Because HTTP is stateless, services on the server must be stateful. The initial purpose of Cookie creation is to store the status information on the web for the convenience of use by the server. For example, determine whether the user visits the website for the first time. Currently, the latest specification is RFC 62
difficult for you to solve this problem unless you do not use cookies at all but use other mechanisms to save user-related information. A common method for saving user information is session status, which depends on cookies. This is described in the cookie and session status.

What is cookies?
