- How to detect time zone change with Golang?
- The Go language provides a method for detecting time zone changes: Load the initial location of the time zone: Use time.LoadLocation to load the *time.Location value of the specified time zone. Periodically reload the time zone position: Reload the time zone position periodically, either in a loop or using a timer, and compare it to the initial position. Detect changes: If the newly loaded location is different from the initial location, the time zone has changed.

- How to choose the right C++ generic programming technique?
- C++ generic programming technologies include: 1. Template metaprogramming: generate code at compile time, efficient and type-safe; 2. Runtime type information: obtain type information, flexible but expensive; 3. Type blanking: the compiler infers types, Easy to use but may lead to unexpected derivation.

- How does Go WebSocket handle errors?
- WebSocket error handling in Go is divided into the following two categories: Parse/ValidationErrors: Parsing or validation errors, such as this bad handshake request. ConnectionErrors: Errors in establishing or maintaining connections, such as network connection disconnection or timeout. Methods of handling errors include directly checking the error variable, using defer statements, and using error wrappers. By handling errors correctly, robust and reliable WebSocket connections can be established in Go applications.

- Differences in the implementation methods of the PHP framework in different versions of PHP
- The differences in the methods of implementing the PHP framework in different PHP versions are mainly reflected in namespaces and automatic loading. In versions prior to PHP 5.3, the framework code needs to use fully qualified names and manually register the autoloading function. In PHP5.3 and later versions, namespaces can be used, and the autoloading function can be registered using the spl_autoload_register() function.

- Best practices and design patterns of Golang framework
- Golang Framework Best Practices and Design Patterns Adhering to best practices and design patterns helps in building reliable, scalable and maintainable Golang applications. Best practice: Use structs and interfaces for loose coupling and testability. Separate business logic and data layers to improve reusability and testability. Use goroutines to improve application performance. Use built-in error types for clear and consistent error handling. Design Pattern: Singleton Pattern: Ensure that a class has only one instance. Factory pattern: Provides a unified way to create objects. Service Locator Pattern: Simplifying dependency management. Observer pattern: loose implementation

- How do C++ smart pointers compare to smart pointers in other languages?
- The implementation of smart pointers varies in different languages. In C++, smart pointers take exclusive ownership and use destructors to release resources. In Java, smart pointers do not have ownership and resources are automatically released by the garbage collector, but the release time is uncertain.

- How to use factory pattern in PHP?
- The factory pattern in PHP allows to generate objects without specifying the exact class. It is suitable for creating a large number of objects without knowing the actual category: defining the Product interface and specific product classes such as ProductA and ProductB. The Create Factory class provides the createProduct method to create the corresponding product by specifying the type (such as 'A'). Use Factory::createProduct('A') to create the required type of product to improve code maintainability, reusability and dynamic creation flexibility.

- Architectural design for building enterprise applications using PHP framework
- PHP framework architecture design is crucial for building enterprise-level applications. MVC, layered, and microservice architectures are three common patterns: The MVC (Model-View-Controller) pattern separates the business logic, user interface, and interactions of an application. The layered architecture divides the application into data access layer, business logic layer and presentation layer to improve scalability and modularity. Microservices architecture decomposes applications into loosely coupled independent microservices, enhancing flexibility, maintainability, and scalability.
