Heroku is an industry-changing service that is established in 2007. It transformed how developers create and deploy apps today. With its add-ons marketplace, Heroku became the development hub that you can easily enable 3rd party cloud services. These services can be in many different categories that a web application may require. From database services, caching, image processing to mail delivery and so on…
Heroku supports many modern development languages that are actively used with big communities like PHP, nodejs, ruby, python, go, java… The beauty of the Heroku applications is that, managed by Heroku and very very easy to understand. They are also very easy to scale, deploy apps in Heroku infrastructure… All Heroku apps are deployed to given app name’s subdomain under herokuapp.com or can be easily set to have a custom domain for free.
Essentially, Heroku runs on a command line interface and an internal git repository to manage versions of your code. When you set up a new project folder, Heroku CLI tool registers your app and assigns a git repository. Heroku CLI doesn’t initiate git repository on your folder, so if it’s a non-git folder, you need to git init on your project folder first.
$ mkdir hello-world && cd hello-world
$ echo "{}" > composer.json
$ echo "<!--? print 'hello';" --> index.php
$ git init
$ heroku create

I highly suggest all developers adapt Heroku in their workflow, at least for the sandbox & playground purposes.
I have created some boilerplate repositories in the past:
