到期自动解禁功能实现
朋友们..想请教一个问题...假如我封禁一个用户一天....一天到期后,自动解禁功能通常是怎么实现的呢?..
------解决方案--------------------
脚本定期执行，把到期解禁的用户解禁
------解决方案--------------------
同意在登陆时做检查。
1.封禁用户最多占网站整体用户的20%(如果封禁用户到达80%，那这个论坛也就快关了)，没必要用80%的时间做各种各样的设计和开发(诸如自动执行脚本之类，这会给你增加维护成本)；
2.封禁用户并非网站的典型用户，即使他登陆时，sql查询慢点，有何不可？别本末倒置；
------解决方案--------------------
为什么要每次SQL查询来判断呢？你可以在登陆的时候就把数据读出来，跟登陆状态放一起（一般是Session或者Cookie），直接与这里的数据对比就行了。

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AMPHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AMIn PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.
