Rob Allen has posted a quick tutorial to his site showing how to user Composer in a PHP project on OpenWhisk. OpenWhisk is Apache's serverless cloud platform that's easy to scale and relatively easy to use. This is the latest in a series of posts from Rob covering its use in PHP projects.

Every PHP project I write has dependencies on components from Packagist and my Serverless OpenWhisk PHP projects are no different. It turns out that adding Composer dependencies is trivial.

He uses a simple action that coverts a number to the matching string, showing the yaml configuration changes and code to include to define the action. The action makes use of the NFNumberToWord package which is then added via Composer. He deploys the action and calls it directly, showing the result to be the correct string for the number "123". He also mentions an archive file (zip) that the serverless functionality creates containing all of the files related to the project. He shows the configuration option you can use to split these by action, making it easier to create a more modular system.
