Using selected PHP frameworks in async mode

There are a number of other PHP frameworks that implement the asynchronous programming model. In this section, we cover ReactPHP, the most popular of the PHP async frameworks, as well as Amp, another popular PHP async framework. In addition, we show you how selected PHP frameworks can be used in async mode.

It's important to note that many of the PHP frameworks able to operate in asynchronous mode have a dependency on the Swoole extension. The one that does not have this dependency is ReactPHP, covered next.

Working with ReactPHP

ReactPHP (https://reactphp.org/) is an implementation of the Reactor software design pattern and was inspired by the non-blocking asynchronous Node.js framework (https://nodejs.org/en/), among others.

Although ReactPHP does not give you the automatic performance increase seen with the Swoole extension, it has a big advantage in that it does not rely upon features of UNIX or Linux, and can thus run...
