What does Swoole mean?

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.

What is Swoole written in?

Swoole is written in pure C language and provides asynchronous multi-threaded server in PHP language, asynchronous TCP/UDP network client, asynchronous MySQL, asynchronous Redis, database connection pool, AsyncTask, message queue, milliseconds Timer, asynchronous file reading and writing, asynchronous DNS query. Swoole has built-in Http/WebSocket server/client and Http2.0 server.

In addition to the support of asynchronous IO, Swoole has designed multiple concurrent data structures and IPC communication mechanisms for PHP multi-process mode, which can greatly simplify the work of multi-process concurrent programming. It includes concurrent atomic counters, concurrent HashTable, Channel, Lock, inter-process communication IPC and other rich functional features.

Swoole2.0 supports Go language-like coroutines, which can use fully synchronous code to implement asynchronous programs. There is no need to add any additional keywords to the PHP code. The bottom layer automatically performs coroutine scheduling to achieve asynchronous implementation.
