The choice of PHP framework depends on project needs and developer skills: Laravel: rich in features and active community, but has a steep learning curve and high performance overhead. CodeIgniter: lightweight and easy to extend, but has limited functionality and less documentation. Symfony: Modular, strong community, but complex, performance issues. ZendFramework: enterprise-grade, stable and reliable, but bulky and expensive to license. Slim: micro-framework, fast, but with limited functionality and a steep learning curve.

There are differences in the performance of PHP frameworks in different development environments. Development environments (such as local Apache servers) suffer from lower framework performance due to factors such as lower local server performance and debugging tools. In contrast, a production environment (such as a fully functional production server) with more powerful servers and optimized configurations allows the framework to perform significantly better.

Integrating PHP frameworks with DevOps can improve efficiency and agility: automate tedious tasks, free up personnel to focus on strategic tasks, shorten release cycles, accelerate time to market, improve code quality, reduce errors, enhance cross-functional team collaboration, and break down development and operations silos

The Java framework supports horizontal expansion of microservices. Specific methods include: Spring Cloud provides Ribbon and Feign for server-side and client-side load balancing. NetflixOSS provides Eureka and Zuul to implement service discovery, load balancing and failover. Kubernetes simplifies horizontal scaling with autoscaling, health checks, and automatic restarts.

Create a distributed system using the Golang microservices framework: Install Golang, choose a microservices framework (such as Gin), create a Gin microservice, add endpoints to deploy the microservice, build and run the application, create an order and inventory microservice, use the endpoint to process orders and inventory Use messaging systems such as Kafka to connect microservices Use the sarama library to produce and consume order information

PHP and Python frameworks differ in language features, framework ecology, and features. PHP is primarily used for web development and is easy to learn; Python has an extensive library ecosystem. Popular PHP frameworks include Laravel, CodeIgniter, and Symfony; Python frameworks include Django, Flask, and Web2py. In practical cases, Laravel uses the command line to generate blog models and views, while Django uses DjangoAdmin and Python scripts to create blogs.

When preparing for an interview with Yii framework, you need to know the following key knowledge points: 1. MVC architecture: Understand the collaborative work of models, views and controllers. 2. ActiveRecord: Master the use of ORM tools and simplify database operations. 3. Widgets and Helpers: Familiar with built-in components and helper functions, and quickly build the user interface. Mastering these core concepts and best practices will help you stand out in the interview.
