In the third and last part of my series of posts, I have tested one of many components from Zend Framework, one of the most mature, tested and complete PHP frameworks available. Although it is possible to use this component outside a standard ZF application, there are several extra configurations needed or the adoption of other components like Zend_Loader and Zend_Exception. As they don’t apply for this article’s scope, this kind of situation was intentionaly ommitted.
In a typical MVC application, Zend_Db is the tool responsible for encapsulating all the operations done in the model layer. In addition to database abstraction, it has other classes implementing object-relational mapping patterns, which will be presented in a new series of articles.
