现在我的服务是在nginx + fpm 方式运行。
请问php用cgi跑和fpm跑有什么区别么?
php新手对这两概念不太了解,求教各位。

用fpm更好。
cgi是最原始的方式,即Nginx针对每一个请求,创建一个PHP解释器进程,处理完请求后,进程销毁。
fastcgi算是cgi的升级版,Nginx会创建一个(或多个)持久的进程,逐个处理请求,省去了创建和销毁进程的开销。
phpfpm是PHP的fastcgi管理器,有很多实用的功能(如灵活地配置进程池管理策略), 应该说是和Nginx配合的最佳选择。
PHP-FPM 是为 PHP 内核编写的补丁,用来根据需要处理 FastCGI 进程的启动、停止、重启。
- 较低的内存占用率(因为 nginx 单独运行时不用加载整个 PHP 环境)。
- 轻松地管理用户权限(因为 PHP 可以在你的服务器进程中管理不同的用户)。
- 当 PHP 崩溃时,nginx 可以照常运行。
最近有消息称,PHP5.4 将很有可能把 PHP-FPM (PHP FastCGI 进程管理器)补丁包含在内核里。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
