先检查发送表单后的数据:print_r($_POST); ,看看有没有把数据发送出去
然后去数据库里查看是否真的修改成功
最后看看你改的那条和你查的那条是不是同一条
你修改后有刷新下页面吗?
先清理一下浏览器缓存,再打开页面看看
楼主的意思是,数据库数据更新,但是页面数据未更新,是这个意思吗?
首先确认你是否修改成功。
我确认过,数据库已更新了,但是页面显示的还是原来的数据。
修改成功后用location跳转到这个地址试一试。
设置一下页面禁止缓存
<?php header("Pragma: no-cache"); ?>

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
