Enterprise Ready 已經有成功的企業例子。
- An entirely re-written event-driven MVC layer
- Components practice dependency injection, supported by our Service Locator and DiC components
- A powerful module management system
- An EventManager, for writing event-driven systems, as well as for creating cut points in your software for introducing cross-cutting concerns.
- A new view layer, architected around analyzing the request and generating a suitable response, be it plain old HTML, or Atom feeds or JSON.
簡而言之，
- PHP 5.3 feaetures such as namespace and closures
- A modular application architecture
- Event manager
- Dependency Injection (DI)
- ZF2的MVC全被包在模組(Module)裡面。
- ZF模組資料夾結構：
- config：管理模組設定。
- src：所有模組程式碼，包含controllers和models。
- view：存所有模組會用到的views。
- Module Manager是找
Module.php檔案作設定，並呼叫getAutoloaderConfig()和getConfig()兩個方法。 getAutoloaderConfig()會載入autoload_classmap.php檔案，去include自定覆載的類別，故可在```autoload_classmap.php``新增或刪除Entries來管理自定覆載。getConfig()會載入```config/module.config.php``檔案，去設定模組設定參數，包含routes,controllers,layouts，以及其它設定。- ZF2的ServiceManager實作服務分配者design patter，使用service/object分配者去檢索其他物件，分為六大類：
- abstract_factories：定義抽象類別陣列。
- aliases：定義alias name/target name關聯陣列。
- factories：定義service name/factory class name pair陣列。
- invokables：定義service name/class pair陣列。
- services：定義service name/object pairs陣列。
- shared：定義service name/Boolean pair陣列。
- ServiceManager設定可選擇application或module層級設定。
- 關鍵factories可放至ServiceManager：
- Database connections
- Models and table gateways
- Form and filters
- Authentication service
- TableGateway類別繼承AbstractTableGateway，且實作TableGatewayInterface。
- TableGatewayInterface提供CRUD介面。
- getTable()
- inser($set)
- select($where = null)
- update($set,$where=null)
- delete($where)
- Model
- Create necessary tables.
- Create necessay table gateway object for data access.
- Controller
- indeAction：list all products
- productDetailAction：display the details of a specific product and allow the user to add a product to the cart.
- shoppingCartAction：render the shopping cart before leaving for the payment processing page.
- paypalExpressCheckoutAction： redirect the user to the Paypal Express Checkout page.
- paymentConfirmAction：handle the redirection from PayPal Express Checkout back to the shopping cart upon sucessful payment.
- paymentCancelAction：handle the redirection from PayPal Express Checkout back to the shopping cart upon failed payment.
