Getting Started With Serverless PHP

I’ve been interested in Apache OpenWhisk for a little while now and recently submitted a new feature to add PHP support to the project. As OpenWhisk is a serverless environment, most users do not run their own copy and instead use a commercial provider with IBM’s Bluemix available now along with Adobe’s I/O Runtime and RedHat coming soon. As a result, my contribution isn’t practically useful until it’s in production with a provider.
Fortunately, and remarkably quickly, IBM has added support for PHP to the Bluemix “IBM Cloud Functions" platform, so now we can use PHP to develop serverless applications and deploy them into the wild! This is a rebranding, so you’ll see this referred to as "Bluemix OpenWhisk" around the web too.
