Use the above code to detect whether it is in json format, and the effect is good. Attachment, the solution to the Chinese problem when php processes json When converting the object into json, one of the Chinese attributes became null.
Everything is normal when there is no Chinese, the output is as follows: {"PlatformID":"123213","UserID":"1023"} The following two exceptions will occur in Chinese. Case 1, if an attribute whose value is Chinese in the object itself is UTF-8 encoded, there will be the following output: {"PlatformID":"123213","UserID":"1023","UserName":"u00b7u00f0u00b5u00b2u00c9u00b1u00b7u00f0u00ccu00fc"} The UserName is in a non-human language. If you use firebug to see it, it is in Chinese. Case 2, non-utf-8 encoding, the output will become null: {"PlatformID":"123213","UserID":"1023","UserName":null} After checking the manual, I found that json_encode is only valid for utf-8, and other encodings will become null. How to solve the problem of encoding conversion? Consider the following example. Example:
Conclusion: 1. Ensure that the character set of the page is consistent with the database, and the output must be normal. 2. When doing json_encode, ensure that the data encoding is utf-8 and json_decode is normal. 3. If you want to json_encode non-utf-8 characters, convert them to utf-8 first. 4. When doing json_decode on non-utf-8 characters, remember to convert to the original encoding, otherwise garbled characters will be output. |

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,

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.
