Gonzalo Ayuso has a tutorial posted to his site showing you how to create a PHP application on a SAP platform that includes PostgreSQL and Redis via Cloud Foundry.

Keeping on with my study of SAP’s cloud platform (SCP) and Cloud Foundry today I’m going to build a simple PHP application. This application serves a simple Bootstrap landing page. The application uses a HTTP basic authentication. The credentials are validated against a PostgreSQL database. It also has a API to retrieve the localtimestamp from database server (just for play with a database server). I also want to play with Redis in the cloud too, so the API request will have a Time To Live (ttl) of 5 seconds. I will use a Redis service to do it.

He then walks you through the process of setting up both the platform and the application:

• creating the services in cloud foundry
• create our application (with either Silex or Lumen)
• built out the features
• running the application locally for testing
• connecting to the cloud servers for PostgreSQL and Redis
• set up logging
• set up basic authorization

Full code and configuration is included for each step of the way (with Lumen examples included because Silex is "dead").
