Cookie across HTTP and HTTPS in PHP
提问by Paulo Coghi - Reinstate Monica
How can I set a cookie in PHP that is readable both in HTTP and HTTPS?
如何在 PHP 中设置一个在 HTTP 和 HTTPS 中都可读的 cookie？
If this isn't possible, what can be done? Set two cookies?
如果这是不可能的，可以做什么？设置两个饼干？

By default, a cookie can be read by both http and https at the same URL.
默认情况下，同一 URL 上的 http 和 https 都可以读取 cookie。
However, a server can optionally specify the 'secure' flag while setting a cookie this tells the browser to only send it over a secure channel, such as an SSL connection.
但是，服务器可以选择在设置 cookie 时指定“安全”标志，这会告诉浏览器仅通过安全通道（例如 SSL 连接）发送它。
In this case the cookie will only be sent over https. A cookie not marked as secure will be sent over both http and https.
在这种情况下，cookie 将仅通过 https 发送。未标记为安全的 cookie 将通过 http 和 https 发送。

Assuming your domain name remains the same except for the resource type, cookies in PHP (or any language) can be read from both HTTP and HTTPS.
假设您的域名除资源类型外保持不变，则可以从 HTTP 和 HTTPS 读取 PHP（或任何语言）中的 cookie。
e.g.:
例如：
http://www.example.com
https://www.example.com
In this example, the cookies will be readable from each other.
在此示例中，cookie 将可以相互读取。
