To effectively protect phpMyAdmin, multiple layers of security measures must be taken. 1. Restrict access through IP, only trusted IP connections are allowed; 2. Modify the default URL path to a name that is not easy to guess; 3. Use strong passwords and create a dedicated MySQL user with minimized permissions, and it is recommended to enable two-factor authentication; 4. Keep the phpMyAdmin version up to fix known vulnerabilities; 5. Strengthen the web server and PHP configuration, disable dangerous functions and restrict file execution; 6. Force HTTPS to encrypt communication to prevent credential leakage; 7. Disable phpMyAdmin when not in use or increase HTTP basic authentication; 8. Regularly monitor logs and configure fail2ban to defend against brute force cracking; 9. Delete setup and

XSLT parameters are a key mechanism for dynamic conversion through external passing values. 1. Use declared parameters and set default values; 2. Pass the actual value from application code (such as C#) through interfaces such as XsltArgumentList; 3. Control conditional processing, localization, data filtering or output format through $paramName reference parameters in the template; 4. Best practices include using meaningful names, providing default values, grouping related parameters, and performing value verification. The rational use of parameters can make XSLT style sheets highly reusable and maintainable, and the same style sheets can produce diversified output results based on different inputs.

To use regular expressions in C, you need to include header files and use the functions it provides for pattern matching and text processing. 1. Use std::regex_match to match the full string, and return true only when the entire string conforms to the pattern; 2. Use std::regex_search to find matches at any position in the string; 3. Use std::smatch to extract the capture group, obtain the complete match through matches[0], matches[1] and subsequent sub-matches; 4. Use std::regex_replace to replace the matching text, and support the capture group with references such as $1 and $2; 5. You can add an iset when constructing the regex (
