mysql字符串类型的字段排序问题
我有一个字段A，varchar类型。里面有3条数据，经过order by A DESC排序之后，顺序如下2013.03、2013.02、2013.04
请问如何做到时间最新的排在前面？在不修改数据表字段类型的前提下。
回复讨论(解决方案)
假设你这个2013.03的字段是 shijian
order by A DESC,shijian desc
order by 可以多个字段的
假设你这个2013.03的字段是 shijian
order by A DESC,shijian desc
order by 可以多个字段的
关键是2013.03的字段就是A啊
我试了下 顺序是按照你要求的来的... 不知道为什么你不能得到同样的结果...

你的字段类型是varchar吗？
是varchar

你这么一说，我回去又看看，哎，发现数据又正常排序了。我都不知道为什么。太邪门了。
为了保险起见，我最终拆分成了两个字段。一个用来保存年，一个用来保存月，都是整型。排序比较靠谱点。
我还是不明白，今天明明排序不正常的，我还琢磨很久，到了晚上又正常了。邪门。

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,
How does session hijacking work and how can you mitigate it in PHP?

What are Enumerations (Enums) in PHP 8.1?
Apr 03, 2025 am 12:05 AM
The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.
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.
