PHP：设置 cookies - 由于某种原因旧值没有被替换
我有一个脚本，其中设置了 2 个 cookie：
$month = time() + 60 * 60 * 24 * 30;
setcookie('id', $id, $month, '/');
setcookie('auth', $auth, $month, '/');
header('Content-Type: text/html; charset=utf-8');
print('<html><body>...etc....');
这确实工作得很好，但是：有些用户有多个 id，具体取决于他们通过 iframe 访问我的脚本的页面（社交网络）。
一个用户拥有多个 id 不是问题。但我的问题是，当我要求那个人查看他的 cookie 时，他会报告有几个名为 id 和 auth 的 cookie。我也可以自己复制它。
我实际上期望总是只有 1 个 id 和 1 个 auth cookie。
我在这里能做什么？
使用新值调用 setcookie('id', ...) 不会替换旧值吗？
谢谢你！ 亚历克斯
I have a script where I set 2 cookies:
$month = time() + 60 * 60 * 24 * 30;
setcookie('id', $id, $month, '/');
setcookie('auth', $auth, $month, '/');
header('Content-Type: text/html; charset=utf-8');
print('<html><body>...etc....');
This does work well, but: some users have several id's, depending on from which page (social network) they access my script through an iframe.
A user having several id's is not a problem. But my problem is that when I ask that person to look at his cookies, he'll report that there are several cookies called id and auth. And I can reproduce it myself too.
And I was actually expecting there always to be just 1 id and 1 auth cookie.
What can I do here?
Doesn't calling setcookie('id', ...) with a new value replace the old value?
Thank you!

Cookie 基于 KV 方案（Key=Value）概念，并且 Key 充当唯一标识符。
setcookie的三个主要效应器是setcookie("id","value") 创建 cookie$_COOKIE["id"]读取 cookiesetcookie("id","new value") 更新 Cookiesetcookie("TestCookie", "", time() - 10);所以是的，你的问题是正确的，你应该看看其他可能阻止 cookie 状态的因素。
Cookies are based on a KV Scheme (Key=Value) concept and the Key's act as unique identifiers.
The three primary effectors of
setcookiearesetcookie("id","value")$_COOKIE["id"]setcookie("id","new value")setcookie ("TestCookie", "", time() - 10);so yes your correct in your question, you should have a look at other factors that may deter the cookie states.
