Over the years, software teams have questioned if PHP is a good choice for building web services. In this talk, I will share how we use PHP on the backend for Glu Mobile’s flagship mobile game Design Home, enabling it to regularly rank amongst the top free mobile games - both in downloads and grossing - since its launch in the Apple App Store and the Google Play Store in Q4 2016. Design Home reaches over 1 million daily active users, serving over 100,000 requests per minute while maintaining a user base of over 30 million players. To date, over 1 billion designs have been made by players. We will deep dive into the thought processes, development, testing and deployment strategy, showcasing what we have achieved with PHP and why we love it and rely on it. My goal is to share with the community that, when done the right way, PHP can be used to build and maintain reliable, massively-scalable and high-performance backends using web services.
