On his MaltBlue.com blog Matthew Setter shares his opinion on TableGateways in Zend Framework v2 and wonders if they're "worth it" (as they're not the easiest thing to implement).

Are TableGateways too hard to implement in Zend Framework 2? Are they too hard to justify the effort? That’s what I was asked recently during a Twitter conversation. For me, they’re not. For me, they’re well worth the effort. So I’ve written this post to show why they’re not, and how they bring great flexibility, when implemented correctly. In [this post] I’ll set out why they can be a good solution, as well as why not.

He starts from the origins of PHP scripts, back when they were "a collection of files" and not structured under much of a framework. Complexity added the need for this structure, though, including things like design patterns for common tasks. The TableGateway was one of these. He talks briefly about implementing them in Zend Framework v2 (with some gist examples) and some questions to ask helping you determine if they're "too much" for you app.
