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.

Using string fields and PHP enumeration is the best way to handle enumerations in Laravel. 1. Use string type fields in the migration and optionally add checkIn constraints; 2. Define PHP enum with string backing value (PHP8.1); 3. Automatically convert fields into enum instances through $casts in the model; 4. Use Rule::in(Enum::values()) in form verification to ensure that the input is legal; 5. Use Enum::cases() or fake()->enum() in factory and seed files to generate test data; 6. Use the ->value attribute of the enum or directly compare the enum instances when querying. Should
