IntroductionWhen building a website using Zend Framework MVC layers, your view scripts will typically be just snippets of HTML pertinent to the requested action. For instance, if you had the action "/user/list", you might create a view script that iterates through the users and presents an unordered list: Since this is just a snippet of HTML, it's not a valid page; it's missing a DOCTYPE declaration, and the opening HTML and BODY tags. So, the question is, where will these be created? In early versions of Zend Framework, developers often created "header" and "footer" view scripts that had these artifacts, and then in each view script they would render them. While this methodology worked, it also made it difficult to refactor later, or to build composite content by calling multiple actions.
The Within Zend Framework, Zend_Layout implements the Two Step View pattern.
