Why Do Session Cookies Disappear in Chrome, but Not Firefox?
Session Cookies Misbehaving Solely in Chrome
While navigating within a shopping cart application, a peculiar issue surfaced: session data stored was retained in Firefox but mysteriously vanished in Google Chrome. Despite correct session initialization procedures, variables such as 'last_viewed_element' were persistently lost in Chrome.
This behavior extended to all session variables, as evidenced by the lack of response in Chrome upon accessing $_SESSION. However, upon delving into the network monitor, it was clear that session cookies were being transmitted.
Unconventional Solution: Replacing Sessions with Cookies
To resolve this puzzle, an unorthodox solution was discovered. By switching from session cookies to regular cookies, the issue vanished.
Underlying Cause: Chrome's Response to 404 Error
Further investigation revealed that Chrome was triggering a 404 error due to a missing favicon.ico. This 404 call executed the footer script, which subsequently altered the session variables, explaining their disappearance.
This unusual phenomenon highlights the importance of considering potential interactions between browser-specific behavior and session handling in web applications.

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.
