Why is all the field information cleared after I click the browser's back button? _PHP Tutorial
Q: Why is the information in all fields cleared after I click the browser's back button?
A: This is because you used the session_start function in your form submission page. This function will force the current page to not be cached. The solution is to add header("Cache-control: private"); after your Session_start function; Note that your PHP program cannot have any output before this line.

Is the conversion speed fast when converting XML to PDF on mobile phone?
Apr 02, 2025 pm 10:09 PM
The speed of mobile XML to PDF depends on the following factors: the complexity of XML structure. Mobile hardware configuration conversion method (library, algorithm) code quality optimization methods (select efficient libraries, optimize algorithms, cache data, and utilize multi-threading). Overall, there is no absolute answer and it needs to be optimized according to the specific situation.
Does XML modification require programming?
Apr 02, 2025 pm 06:51 PM
Modifying XML content requires programming, because it requires accurate finding of the target nodes to add, delete, modify and check. The programming language has corresponding libraries to process XML and provides APIs to perform safe, efficient and controllable operations like operating databases.

What is the priority of C language !x?
Apr 03, 2025 pm 02:06 PM
The logical non-operator (!) has the priority next to parentheses, which means that in expressions, it will precede most other operators. Understanding priority not only requires rote memorization, but more importantly, understanding the logic and potential pitfalls behind it to avoid undetectable errors in complex expressions. Adding brackets can clarify expression intent, improve code clarity and maintainability, and prevent unexpected behavior.
Best practices for C language default
Apr 03, 2025 pm 03:48 PM
The best practices of default in C language: place it at the end of the switch statement as the default processing for unmatched values; it is used to handle unknown or invalid values to improve program robustness; avoid duplication with case branches to maintain conciseness; comment clearly on the purpose of the default branch to improve readability; avoid using multiple defaults in one case to maintain clarity; keep the default branch concise and avoid complex operations; consider using enumeration values as case conditions to improve maintainability; in large switch statements, use multiple default branches to handle different situations.

Tutorial on how to represent the greatest common divisor in C language functions
Apr 03, 2025 pm 11:21 PM
Methods to efficiently and elegantly find the greatest common divisor in C language: use phase division to solve by constantly dividing the remainder until the remainder is 0. Two implementation methods are provided: recursion and iteration are concise and clear, and the iterative implementation is higher and more stable. Pay attention to handling negative numbers and 0s, and consider performance optimization, but the phase division itself is efficient enough.
