msyql奇怪的问题，求解释。
如图按主键降序排列
没看到1913这个id。但是我如果直接用sql查询的话，会显示成这样
回复讨论(解决方案)
可能你在别的字段上做了唯一索引
建议你用sql语句试一下

只有主键是唯一索引。之前好好的啊，突然这样，觉得很奇怪，难道mysql还有隐藏数据的功能?
建议你用sql语句试一下
用sql排序limit显示为空，如果用where条件就可以显示出来。郁闷！
应该不可能，在dos命令行试一下。

我就是用mysql控制台直接执行sql的！
软件问题吧！
这个 是不是数据库配置的问题啊、

那就明显是人的错误了。不是语句有问题，就是软件使用上存在失误。所有程序诡异的问题，原因都是人。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
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,
Describe the SOLID principles and how they apply to PHP development.
Apr 03, 2025 am 12:04 AM
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.

Explain late static binding in PHP (static::).
Apr 03, 2025 am 12:04 AM
Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
