Rob Allen:
Getting started with Serverless PHP

In a new post to his site Rob Allen talks about getting up and running with "serverless PHP" using the Apache OpenWhisk cloud platform that executes as events are fired rather than sitting as an entire application.

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 IBMs Bluemix available now along with Adobes 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 have 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.

He walks you through the setup of an account on the bluemix.net service and how to install OpenWhisk locally rather than the IBM "Bluemix CLI" tool. He then shares the code to create a simple "Hello World" function in PHP (7.1) and push it up to your account. He then executes the action from the command line, returning his JSON formatted greeting. Next he shows how to set this function up as a web action and give it a URL for the outside world to access. He finishes the post with some examples of calling the URL and how it would receive parameters via a POST or a GET.
