In his latest post Robert Basic looks at working with custom view helpers in your Zend Framework 2 application and shows how to implement a simple one to display a simple greeting.
I took the skeleton [Zend Framework 2] application, made it even skinnier by throwing out some (for me) unneeded parts and just put it all besides my old ZF1 code. [...] The first problem I ran into was using custom view helpers, especially view helpers that are more general and don't fit into one specific module. Where to put the code? How to access them in views? The second problem was how to access the service manager from a view helper? And the third problem was how to tell the helper to use a specific value when inside a specific module?
He includes a simple example - the greeting helper - and shows where to place it in the application structure, how to work with the service locator inside it and how to set up some module-specific views inside.
