The SitePoint PHP blog has posted a tutorial for those using the Laravel Cashier showing you how to work with memberships for the content or functionality of your application.
In this tutorial we’re going to see how easy it is to create a basic paid membership website using the Laravel Cashier package. You can see a demo of the app here and download the source code here.
The tutorial walks you through setting up a functional environment and getting the new Laravel instance up and running. Migrations to run are included in the repository checkout too. The tutorial then gets into the setup of Stripe for payments and creation of the various pages you'll need. An "upgrade" option is also included.
