AWS Lambda PHP Hello World

The basics of using Serverless Framework for AWS Lambda PHP applications.

Notes

1. Install Serverless Framework by following the Quick Start
2. Set up your AWS credentials
3. Create php binary layer and upload to AWS by following steps in php-runtime/README.md
4. Write your serverless application (!) - the default is in hello-world/handler.php
5. Run sls deploy to deploy to Lambda
6. Run sls invoke -f hello -l to invoke your function

As we've used Docker to create the runtime, you can test locally using the Dockerfile in hello-world:

$ cd hello-world
$ docker build -t lambda-php-test . && docker run lambda-php-test handler.hello '{"name": "world"}'

PHP handler function signature

The signature for the PHP function is:

function main($eventData) : array

Hello world looks like:

<?php
function hello($eventData) : array
{
    return ["msg" => "Hello from PHP " . PHP_VERSION];
}
