Swoole Introduction:

Swoole is a PHP asynchronous network communication engine for production environments, allowing PHP developers to write high-level 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 and enter the event loop after running. When an IO event occurs, the underlying layer will automatically call back the specified PHP function.

Includes the following special functions:

1. ORM-like data query, providing a SQL wrapper that allows MySQL's SQL to interact with PHP's Array, session, and Cache Seamless integration.

2. App MVC layered structure, effective program structure layering, improve program maintainability and scalability, achieve low coupling, and interface-based development.

3. Integrate a large number of practical functions, such as convenient database operations, template operations, cache operations, system configuration, form processing, paging, data calling, dictionary operations, upload processing, content editing, debugging, etc.

4. The template-data reflection system can directly call data in the template and provide many tags. It can realize various updates and maintenance of the website without modifying the program and only modifying the template.

A few other functions

1. Swoole contains a large number of classes and provides many functional extensions. Basically, most of the functional classes that can be used in web development All can be found in the Swoole framework.

2. Swoole has a plug-in system, Fckeditor, Adodb, pscws Chinese word segmentation, Chinese full-text indexing system, the latest Key-Value database idea, TokyoTyrant, which can infinitely expand the functions of the framework.
