Understanding DOMDocument in PHP: Node Hierarchy and Processing
When working with the Document Object Model (DOM) in PHP, it's crucial to grasp the concept of node hierarchy. Every component in a DOMDocument, including the document itself, is a Node.
Node Types
Each node in a DOMDocument can be categorized into one of these types:
- Uppercase: DOMElement (e.g., HTML, DIV)
- Lowercase: DOMAttr (e.g., class)
- "Quoted": DOMText (e.g., "The

What is a session in PHP, and why are they used?May 04, 2025 am 12:12 AMSession in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

What is the difference between absolute and idle session timeouts?May 03, 2025 am 12:21 AMAbsolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.
What steps would you take if sessions aren't working on your server?May 03, 2025 am 12:19 AMThe server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
