The main reason why js uses history.back to return form data is because session_start(); is used. This function will force the current page not to be cached. This article introduces to coders the solution to the loss of form data after php history.back returns. Interested coders can refer to it.
The solution is as follows:
Add header("Cache-control: private"); after your Session_start function; Note that your PHP program cannot have any output before this line.
There is also a session-based solution, add
session_cache_limiter('nocache');//Clear the form
session_cache_limiter('private'); //Do not clear the form, only while the session is in effect
session_cache_limiter( 'public'); //Do not clear the form, as if the session is not used

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.
