For years, Facebook has been written in the programming language PHP. But as technology evolves, it can be hard to keep up with the latest trends and changes. So, is Facebook still written in PHP?
The short answer is yes. As of 2020, Facebook is still written primarily in PHP. The social media giant has been built on this language since 2004 and is unlikely to change anytime soon.
However, even though PHP is still used for the majority of the codebase, Facebook has implemented some other technologies over the years. For example, they began using C++ for some components back in 2010. They’ve also recently begun experimenting with other languages such as Hack and React Native.
At its core, however, Facebook still remains a largely PHP-based platform. This is partly due to its open-source nature and ease of use for developers. It allows engineers to quickly build features and make changes without having to completely overhaul their codebase.
