php查询数据库的int字段，打印出来怎么是字符串类型呢？
array(9) {
["id"]=>
string(1) "1"
["radioname"]=>
string(1) "小二"
["author"]=>
string(9) "小三"
["did"]=>
string(1) "1"
.............
就连主键自增的id也是字符串类型，求解，谢谢

对，是这样的
传入的数据都是字符型的
但这并不影响数据的使用

查出来的数据用做java的接口，他们要求给数字类型，如果没办法，只能查出来之后用intval()转一下

再怎么变，传到java时也还是串

啊，那客户端的同学让我给int，欺负姐不懂科学

很简单，你说让他 post 个 int 给你才能返回 int 给他

额，是我没描述好，查出来要生成json
"id":"1"
"id":1
客户java解析的办法就不一样了吧
都是一样的，JSON的标准格式是键名和值都以双引号括起的
你自己看一下 json_encode 函数的结果就清楚了

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,

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.
