1 What's new in Zend Framework 2.2? by Enrico Zimuel Software Engineer Zend Framework Team

2 About me Enrico Zimuel Software Engineer since 1996 PHP Engineer at Zend Technologies Zend Framework Core Team International speaker, author of books about web programming Co-founder PUG Torino (Italy)

3 ZF 2.2 in a slide Abstract Factories for common services Initial DDL support for Zend\Db New Service Wrapper ZendService_Api ZendService_OpenStack ZFTool Diagnostic Feature Hydrator Improvements Reducing Dependencies Lazy services using VirtualProxy

4 Abstract Factories The primary focus of the 2.2 release has been usability and consistency, primarily with regard to creation and configuration of services Most of these services now have what are known as "Abstract Factories" that are either registered by default, or can be added quickly to your application configuration Component added with abstract factories: log, caches, adapters subkey of db, forms

5 Abstract Factories: example

6 New Plugin Managers Zend\Stdlib\Hydrator\HydratorPluginManager, for retrieving hydrator instances. This allows re-use of individual hydrators, and coupled with the forms abstract factory, allows usage of custom hydrators across your form instances. Zend\InputFilter\InputFilterPluginManager, for retrieving (configurable) input filter instances We also added 2 new services factories, sessions and translators

7 DDL support for Zend\Db Initial support in Zend\Db for dynamic DDL queries. DDL, for Data Definition Language, is a subset of SQL that comprises different commands for building RDBMS data structures like tables, columns, constraints, indexes, views, triggers and the like Initial support is limited to creating tables with SQL92 data-types, and some specialization for MySQL support

8 Example: CREATE TABLE

9 Example: ALTER TABLE Example: DROP TABLE

10 New ZendService components ZendService_Api, an HTTP microframework for consuming generic API calls in PHP ZendService_OpenStack, a new library to support the last API version of OpenStack (based on ZendService_Api)

11 ZFTool Diagnostic features A new diagnostics feature for ZFTool. Using this feature, we can allow the execution of customized diagnostics tests in ZF2 projects Diagnostic means testing for the required PHP version, testing for specific PHP extensions, testing for specific ZF2 modules, testing for specific PHP INI settings, and more. With the collaboration of the LiipMonitor project, we decided to create common interfaces for performing diagnostic tests in PHP applications

12 Hydrators improvement We added an "Aggregate Hydrator", which allows you to provide specialized mapping of your object types to hydrators via an eventbased system For instance, if you use Doctrine, the Aggregate Hydrator allows you to attach a single hydrator to the parent object, and ensure that all child and descendant objects are either hydrated or extracted according to their type

13 Reducing Dependencies We started to reduce the dependencies between components While this story is primarily slated for 2.3, we have made our first steps in 2.2, with the Zend\Feed and Zend\Validator components.

14 Lazy Services Zend\ServiceManager can use delegator factories to generate lazy references to your services. Lazy services are proxies that get lazily instantiated, and keep a reference to the real instance of the proxied service. We used the ProxyManager project of Marco Pivetta (@ocramius):
