求mysqli取得结果中指定字段的字段名
mysqli取得结果中指定字段的字段名 是哪个 手册里没有找到啊 求高手解答
回复讨论(解决方案)
从数据库出来的数据，不是数组吗。
是一个键值是数字的数组
字段取决于你查询时的字段顺序！！！
好像有个函数叫
mysql_field_name();
这个函数可以返回资源集的字段名
就是你先执行sql查询
把查询到的结果保存到一个变量中
把这个变量 和一个整型数 作为参数
传入这个函数
整型数应该是获得字段名的偏移量
比如你传入0
mysql_field_name($res, 0);
就从这个$res数据集的第一个字段名开始获取
具体你可以搜索一下这个函数的用法
或者自己测试一下
用一下试试就清楚了

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.
