php - 如何在每个页面中使 PHP cookie 全局化

Question

我正在为我的新网站使用 cookie，但我遇到了这个问题:如果我在

上用我的脚本设置一个 cookie

server.dom/scripts/addcookie.php

它会保存我的 cookie 但在

上不可用

server.dom/index.php

我相信我的问题是由路径引起的。知道如何让它全局化吗？谢谢

来自 the documentation :

bool setcookie ( string $name [, string $value [, int $expire = 0 [, string $path [, string $domain [, bool $secure = false [, bool $httponly = false ]]]]]] )

path
The path on the server in which the cookie will be available on. If set to '/', the cookie will be available within the entire domain. If set to '/foo/', the cookie will only be available within the /foo/ directory and all sub-directories such as /foo/bar/ of domain. The default value is the current directory that the cookie is being set in.

因此将第 4 个参数设置为 setcookie 为 '/'
