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 Multi-process concurrent programming work. 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.

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 and focus more on developing innovative products.

From this simple introduction, we already know that swoole is a PHP extension written in C, which implements many functions of the network layer.

swoole is currently used by many mobile Internet, Internet of Things, online games, and mobile game companies, replacing complex programming languages ​​such as C and Java to implement network server programs. Using PHP Swoole, development efficiency can be greatly improved.

Officially provides a PHP network framework developed based on swoole extension, supporting Http, FastCGI, WebSocket, FTP, SMTP, RPC and other network protocols

swoole in the United States, United Kingdom, France, There are users in India and other countries, and are used by many well-known domestic Internet companies such as Tencent, Baidu, Alibaba, and YY Voice.

It can be seen that swoole can be applied in many aspects, especially in the mobile Internet, and is used by the three domestic BAT giants, which is enough to show that swoole is very mature and has been tested by actual business !
