PHP输入json数据的问题
我先用SQL查询出数据库里的数据，然后对其进行遍历，最后用 json_encode编码输出，结果输出的不是json类型的，请问各位大神，怎么解决，万分感激！
回复讨论(解决方案)
那就是json数据，你偏要说不是json类型的。
你输出的结果就是json类型 ，只是你这样看的话是有点问题，你去百度在线json格式化 ，把你的数据放进去格式化一下就行了，但是这个数据不影响你的查询结果，只是json显示的问题。
这个结果看起来确实是json，但是我在js里用ajax进行解析，得到结果如下：
1、我在ajax里把datatype写为json，什么结果都得不到
2、我把datatype注释掉，然后输出data，结果得到一个字符串
所以我这里就搞不懂了。
这是哪来的？也算 json 吗？
把html 里的

这个是因为你的这个页面还有HTML代码，所以你在echo $phptest; exit;增加这个exit;停止输出，记得前面不要用php输出HTML代码
感谢各位大神，问题已解决

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.
