phpmyadmin问题请教
phpmyadmin左侧数据库树形结构为什么会出现这种 有的是好几个库之前出现，有的是好几张表之前出现，在什么情况下回出现这种现象
回复讨论(解决方案)
第一级是 库
第二级是 表
第三级 不清楚
你的 phpmyadmin 比我的高多了

恩，有的是几个库之前有这个结构（某些同类库的集合？），有些好几张表之前有这个结构（某些同类表的结合？），好郁闷，看了下导出的sql语句，没有发现这种结构，但是在phpmyadmin中就出现这种结构
前面不是有 + 吗，你进去看看不就知道了？
第三极点开看看是什么东西

仔细看一下我的描述，1：数据库之前多出一级，这一级代表什么(这一级没法点，默认没有连接)，2：表之前多出一级（并不是数据库）这一级又是代表什么（这个可以点击，点击以后出现它的几张下级表），这些现象是在什么情况下发生的。
常理树形结构：数据库->表
phpmyadmin的结构： 有时会出现 第一级（没法点击）->多个数据库-> 第三级（有时会出现）->多张表

是分组么。。。。。。
navicat 上面就有这种功能
装了个 phpMyAdmin 4.1
所以你只要点开来看，就知道是什么了
那个是表示分组，会把相同前缀的数据表归入同一分组
只是显示优化，与数据库结构没有关系的。
楼上所有人都看清楚在说

都说了点不开，还在说点开看看，能不能认真看我的描述

看我上面截图，表前缀都是一样的，为什么偏偏有些表或者库前面没有，请看清楚再回答

仔细看一下最上面的两个截图，表前缀都是一样的，仔细看看，想好了再说
大家回答的并没有错，确实是分组啊，相同的前缀归到一个组里了，至于你说点不开，是哪一级点不开，有+号的应该都能点开啊
库前缀相同，就放在一起
有什么可奇怪的
除最后一个_后面的不同，前面都一样，就会有分组
例如
aaa_a
aaa_b
aaa_c
会有分组aa
如果
aaaa_a_b
aaaa_b_c
aaaa_a
这样就没有分组
其实这个是 phpmyadmin根据表名做的优化，方便找到前缀相同的表名，与数据库操作没有任何关系，实际上就是一个js方法做了处理而已。

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?
Apr 06, 2025 am 12:02 AM

Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.
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.
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.
