php - setcookie 路径 url 在 PHP 中不起作用？

Question

从以下代码调用时/foo/controllers/：

setcookie(
    "email", $email, time() + 100 * 60 * 60 * 24 * 30, 
    "/foo/", "bar.com", false
);

它获得价值（从 FireBug 复制）：

# line-breaks added for aesthetics
email=stackoverflowuser95%40gmail.com; 
    expires=Sun, 24 Jan 2021 06:25:33 GMT; 
    path=/foo/controllers/; domain=bar.com

如何设置它以使 cookie 对/foo/controllers/and有效/foo/views/？
