Is Facebook still written in PHP?

Additionally, Facebook makes use of GraphQL, MySQL, Redis, Apache Cassandra, and JavaScript to provide features like chatbots and facial recognition.

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.

Facebook also makes extensive use of several additional technologies that enable it to provide functionality like chatbots and facial recognition. These include GraphQL (a query language used to retrieve data from multiple sources), MySQL (a relational database management system), Redis (an in-memory data structure store), Apache Cassandra (a distributed NoSQL database), and JavaScript (used for client-side development).

In conclusion, although Facebook has added other technologies over the years, it’s still mainly written in PHP. This open source language provides an easy-to-use foundation that allows engineers to quickly build features and make changes without having to completely rewrite their codebase. Additionally, Facebook makes use of GraphQL, MySQL, Redis, Apache Cassandra, and JavaScript to provide features like chatbots and facial recognition.
