#php What should I do if I can’t get the cookie?

The default path of setcookie() is in the current directory. If other directories want to access this cookie, it will not be accessible.

If this parameter is set to '/', the cookie will be Valid in the entire domain

If set to '/foo/', the cookie will only be valid in the /foo/ directory and its subdirectories under the domain

For example, /foo/bar/. The default value is the current directory where the cookie is set.

只需要更改路径就可以了
setcookie("viewlist",1,time()+3600*24*365,'/');
