求一个需求的思路
我开发了一个广告联盟程序，要实现扣量的功能。就是比如本来有100的点击量，设置扣量20%之后就只显示80个。但是现在有个问题，我修改了扣量比例之后，用户再去查询原来的数据就会变，比如用户昨天真实点击有100个，我设置扣20%，就显示80个，今天我设置扣30%，如果用户去查昨天的数据就会显示70个，这样肯定不对啊。求思路，谢谢。
------解决思路----------------------
折扣和时间关联起来不就可以了吗
------解决思路----------------------

引用:

根本就不能让用户知道被扣量了，昨天显示80，今天也应该显示80

最笨的方法就是建一个记录扣量比例 + 时间的表读取数据的时候根据当时的时间找到当时的扣量比例显示数据
------解决思路----------------------
这个似乎只有和时间相关联。然后要现实的时候去读取对应时间的扣量比例计算出要现实的数据。

How can you check if a PHP session has already started?Apr 30, 2025 am 12:20 AM

In PHP, you can use session_status() or session_id() to check whether the session has started. 1) Use the session_status() function. If PHP_SESSION_ACTIVE is returned, the session has been started. 2) Use the session_id() function, if a non-empty string is returned, the session has been started. Both methods can effectively check the session state, and choosing which method to use depends on the PHP version and personal preferences.

How can you manage concurrent session access in PHP?Apr 30, 2025 am 12:11 AM

Managing concurrent session access in PHP can be done by the following methods: 1. Use the database to store session data, 2. Use Redis or Memcached, 3. Implement a session locking strategy. These methods help ensure data consistency and improve concurrency performance.

Explain how load balancing affects session management and how to address it.Apr 29, 2025 am 12:42 AM

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Are there any alternatives to PHP sessions?Apr 29, 2025 am 12:36 AM

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Define the term 'session hijacking' in the context of PHP.Apr 29, 2025 am 12:33 AM

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.
