What is a swoole?

Swoole is a PHP asynchronous network communication engine for production environments, allowing PHP developers to write high-performance asynchronous 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.
