A new tutorial describing how to develop a Z-Ray extension was published on the Zend blog. The tutorial demonstrates just how easy it is to extend Z-Ray by adding new panels with information you think is important for your development work.
Using the publicly available extension APIs (https://github.com/zend-server-extensions), you can easily customize existing Z-Ray panels, or plug in your own extension. The tutorial takes you step by step through the short process of declaring the new extension, enabling it, and defining the function on your page you want to hook into.
The example used in the tutorial is a WordPress application, and the extension created extracts and displays a list of loaded WordPress plugins in Z-Ray.
