The SitePoint PHP blog has a new post from editor Bruno Skvorc showing you how to get started with the Google App Engine support for PHP, specifically through the PHPStorm IDE and it's built in support.
t's been a while since Google announced PHP support on Google App Engine. This article series will take you through all the necessary steps in getting your app up and running on GAE. For this tutorial, we'll be using PhpStorm which supports GAE projects out of the box, but you can use any IDE of your choice. Start by respecting the prerequisites for your platform. This is necessary because the Google App Engine SDK requires certain software to be runnable locally, namely Python which runs the "server".
He goes through the full process, all the way from registering a new application with the Google App Engine service out to configuring and testing a deployment through the IDE. Besides the PHPStorm-based deployment, there's also some brief mentions of how to do the deployment through a normal command line and through git (a push-to-deploy mechanism similar to what other PaaS providers use).
