Upgrading PHP applications
Does upgrading a legacy application seem like a mammoth task? Do functions no longer accept the arguments the application gives them, return different values, or don't even exist anymore? Does testing the code or using a modern framework seem like an unattainable dream?
This presentation will walk you through an upgrade of an old and poorly designed application to the latest version of PHP. Together, we'll write tests for a seemingly untestable beast, discover and solve a myriad of version compatibility issues, introduce a framework, and refactor things along the way to make it easier to upgrade and maintain in the future.
By the end, you will be equipped with the knowledge and confidence to convert legacy applications into modern code, which will make you happy to go to work.

Pre-workshop preparations:

- Install Git
- Clone this repository: https://github.com/afilina/php-upgrade-workshop
- From the cloned directory, run "docker-compose up". It will build and start your containers. Now you're ready for the workshop. Don't expect the app to run in the browser. It's broken on purpose.
