读取多个cookie的方法

如果用户确实查看了该线程，我会为他存储一个 cookie - 该 cookie 包含每个线程中最后一个帖子的 unix 时间，然后我比较实际 cookie 数据和线程最后一个帖子之间的时间。

每个不错的论坛都有一个包含部分和论坛列表的默认页面。现在如何读取我在论坛的每个线程中为此类帖子存储的cookie？

我在想这样的事情：

foreach( $threads as $thread ) {
 if($_COOKIE[@PREFIX."_thread".$thread['id']] < $thread['lastpost'])
   //do action , in case if there are some new posts
 else
   //do action, in there aren't new posts.
}

我现在必须解析 10 个，以后甚至数千个线程。会严重影响服务器性能吗？

I'm storing a cookie for user if he did view the thread - the cookie contains unix time of the last post in each thread, then I'm comparing the time between actual cookie data and the threads last post.

Every nice forum, has a default page with sections and forums list. Now how to read those cookies I was stored for such post in each thread of a forum?

I was thinking at something like:

foreach( $threads as $thread ) {
 if($_COOKIE[@PREFIX."_thread".$thread['id']] < $thread['lastpost'])
   //do action , in case if there are some new posts
 else
   //do action, in there aren't new posts.
}

I'll have to parse now 10 and later even thousands of threads. Will it hurt alot the server performance?

我认为这不是一个好方法，因为没有论坛软件可以做到这一点。其一，如果用户清除 cookie，或使用不同的浏览器，那么所有这些都将丢失。

假设您有一个线程和用户表，我会添加另一个表来记录他们上次看到该线程的时间。

TABLE user_thread_view
{
    thread_id
    user_id
    created (timestamp)
}

然后，当您提取该论坛上的线程列表（每页 10-20 个）时，您可以向该表添加一个调用，以查看该用户和线程的“创建”匹配项是否小于当前的 last_modified线。

I don't think this is a good way to do this based on the fact that no forum software does. For one, if the user clears the cookies, or uses a different browser then all this will be lost.

Assuming you have a thread and user table I would add another table to record when they last saw that thread.

TABLE user_thread_view
{
    thread_id
    user_id
    created (timestamp)
}

Then when you pull out the list of threads on that forum (which is 10-20 per page) you can add a call into this table to see if the "created" match for this user and thread is less than the current last_modified of the thread.
