Question

Good use-case for a Function ?

Posted on May 25, 2022

Asked by Anjanesh Lekshminarayanan

I have a standalone PHP script which is 192K (~3500 lines) that takes an array as user input and returns an huge array of numerous calculations that exists in an XLSX file which I mapped one-by-one in PHP code.

Does this sound as a good use-case for a Function ?
Can I connect it to a MySQL database on a droplet, if required or would be able to connect it to only a dedicated MySQL instance ?
How can I pre-calculate the billing for this script / function ?

You can use a DBaaS instance for the database with your function. We have a couple of examples see here https://github.com/digitalocean/sample-functions-todo and another example https://github.com/rabbah/vitals/blob/master/packages/vitals/records/index.js. I realize these are in JavaScript but using an equivalent library for PHP and adding them to your function dependencies via composer would also work. We should create a php sample or if you’d like to contribute one I’m happy to help. Here is an example php project with dependencies https://github.com/digitalocean/sample-functions-php-numberstowords.

I came across this blog post that is very nice and also uses a DB from a PHP function, thought you might enjoy it https://devdojo.com/bobbyiliev/how-to-use-materialize-with-digitalocean-serverless-functions
