On the NuoDB blog they show you how to take the introductory "News" tutorial for CodeIgniter and set it up to use NuoDB instead of MySQL.

CodeIgniter is a powerful PHP framework with a very small footprint. It is built for PHP coders who need a simple and elegant toolkit to create full-featured web applications. I will show you how you can use NuoDB to power the CodeIgniter tutorial “News” application. [...] In this blog article, I am using clean install of 64-bit Linux Mint 15. (note: the commands and paths below may be different on other Linux distributions).

They walk you through the installation steps and what you'll need to change in your PHP configuration to get everything up and running. He then helps you get CodeIgniter downloaded, set up and configured to use the NuoDB instance. He creates the "news" table and inserts some sample information based on the Ellis Lab tutorial.

On the NuoDB site there's a recent post showing how to use this cloud-based database solution from inside Zend Framework applications.

The Zend Framework is an object oriented PHP framework that can be used to construct interactive web applications. NuoDB supports both Zend Framework version 1 and version 2 . In this TechBlog article, I will show you how to use NuoDB with both Zend Framework v1 and v2. I will use the example applications that are provided in the Zend Framework documentation and show you how to make them work with NuoDB.

They briefly walk you through the install and configuration of Apache and NuoDB you'll need to get things up and running. Sample code is included showing you how to install the NuoDB PDO driver, pull down their github repo with the needed files (for both ZF1 and ZF2) and implementing in each version's quickstart application.
