What is the difference between Workman and swoole

workerman

workerman is a high-performance PHP socket server framework. Workerman is based on PHP multi-process and libevent events. Polling library, PHP developers only need to implement one or two interfaces to develop their own network applications, such as Rpc services, chat room servers, mobile game servers, etc.

Workerman's goal is to make it easier for PHP developers to develop high-performance socket-based application services without having to understand the details of PHP sockets and PHP multi-processes. Workerman itself is a PHP multi-process server framework with PHP process management and socket communication modules, so it can run independently without relying on php-fpm, nginx or apache and other containers.

Workerman has two process models

1. Basic master worker model

2. Master gateway worker model

Master worker model works The process and the relationship between processes are as follows:

Master worker model description:

The master process is the main process and starts the process Read the conf configuration, create a listening socket based on the IP and port in each application configuration, and then create a corresponding number of child processes, that is, worker processes, based on the number of processes in the configuration. The worker process will automatically inherit the listening socket created by the master process. Allows the worker process to accept and handle client connections independently. Then the master process enters the signal monitoring logic and listens for the worker process exit signal (after the worker process exits, the system will automatically send a SIGHCLD signal to the master process, and the master process will re-create the child process and replace the missing child process), master The process will also listen to the stop signal (SIGINT) and smooth restart service signal (SIGHUP) sent by the workermand script.

The worker process is a child process derived from the master process and automatically inherits the listening socket of the master process. Each The worker process accepts and handles client connections independently.

The master worker model is more suitable for simple business applications or short connection applications

The master gateway worker model workflow and relationship between processes are as follows:

Master gateway worker model description:

This model has an additional gateway process group. The workflow is basically the same as the master worker model. The difference is that the worker process no longer directly deals with the client. , there is an additional gateway process between the client and the worker process. The gateway is dedicated to processing network IO and maintaining the client's long connection.

The master gateway worker model is very suitable for long connection applications

swoole

Swoole is a PHP asynchronous network for production environments The communication engine enables PHP developers to write high-performance asynchronous and concurrent TCP, UDP, Unix Socket, HTTP, and WebSocket services. Swoole can be widely used in the Internet, mobile communications, enterprise software, cloud computing, online games, Internet of Things (IOT), Internet of Vehicles, smart homes and other fields. Using PHP Swoole as a network communication framework can greatly improve the efficiency of enterprise IT R&D teams.

Swoole is not a framework like Zend Framework, CakePHP, Yii, symfony, ThinkPHP, etc., nor is it a project on par with open source products such as WordPress, Drupal, Discuz, UChome, etc. Swoole's goal is to challenge first-class frameworks such as Java frameworks, Ruby On Rails, Python DjangoPylons, etc.

Although Swoole is a standard PHP extension, it is actually different from ordinary extensions. Ordinary extensions just provide a library function. The Swoole extension will take over control of PHP after running and enter the event loop. When an IO event occurs, the underlying layer will automatically call back the specified PHP function.

swoole The bottom layer is written in pure C and has almost zero dependence on other extensions. It does not need to depend on the traditional PHP environment. The performance is more powerful, and many large domestic and foreign companies will develop it on the basis of swoole to meet their business needs.
