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.
