In this tutorial, we’ll learn several tips for transpiling from PHP 8.0 to 7.1. Transpiling your code from PHP 8.0 to 7.1 allows you to use the latest features of the language while reaching the most possible users.

Ideally, we should always install the latest version of PHP in our web servers. Right now, that’s PHP 8.0.

In many circumstances, however, this is not possible. Consider situations in which our clients are running legacy software that is incompatible with the latest PHP version. Or maybe we don’t control the environment, such as when building a plugin for WordPress for the general public.

In these situations, transpiling PHP code makes sense because it enables us to use the latest PHP features for development yet release the software with its code converted to an older PHP version for production.

In this article, we’ll learn several tips for transpiling from PHP 8.0 to 7.1.
