ZF2 in a slide● New architecture ▶ MVC, Di, Events, Service, Module● Better performance● Requirement: PHP 5.3.3● No more CLA (Contributor License Agreement)● Git (GitHub) instead of SVN● Packaging system ▶ pyrus, composer © All rights reserved. Zend Technologies, Inc.

Zend Skeleton Application● A simple, skeleton application using the new MVC layer and the module system● How to install: $ cd my/project/dir $ git clone git://github.com/zendframework/ZendSkeletonApplication.git $ cd ZendSkeletonApplication $ php composer.phar install © All rights reserved.

ZendServiceManager ● The ServiceManager is a Service Locator implementation ● A Service Locator is a well-known object in which you may register objects (more in general services) and later retrieve them ● Driven by configuration © All rights reserved. Zend Technologies, Inc.

Types of Services ● Explicit (name => object pairs) ● Invokables (name => class to instantiate) ● Factories (name => callable returning object) ● Aliases (name => some other name) ● Abstract Factories (unknown services) ● Scoped Containers (limit what can be created) ● Shared (or not; you decide) © All rights reserved. Zend Technologies, Inc.

Modules for ZF2● The basic unit in a ZF2 application is a Module● Modules are “Plug and play” technology● Modules are simple: ▶ A namespace ▶ Containing a single classfile: Module.php © All rights reserved. Zend Technologies, Inc.

Develop Modules● Modules contain all logic related to a discrete application problem. ▶ Controllers ▶ Entities ▶ Plugins ▶ Etc.● 99% of the time, you will write modules © All rights reserved. Zend Technologies, Inc.

Pyrus● http://packages.zendframework.com/● Download or use pyrus, a PEAR2 installer● Pyrus packages: ▶ Pyrus setup ▶ wget http://packages.zendframework.com/pyrus.phar ▶ pyrus.phar . ▶ pyrus.phar . channeldiscover packages.zendframework.com ▶ Install a Zend_<component> ▶ pyrus.phar . install zf2/Zend_<component> © All rights reserved. Zend Technologies, Inc.

From ZF1 to ZF2● Goal: migrate without rewriting much code!● Main steps ▶ Namespace: Zend_Foo => ZendFoo ▶ Autoloading: 3 options ▶ MVC: module, event based, dispatchable ▶ DB: new ZendDb ▶ Form: new ZendForm● Can run in parallel (instant migration!) © All rights reserved. Zend Technologies, Inc.

Why ZF2 rocks!● Based on solid architecture principles● Very fast (focused on optimization)● Open architecture (event driven)● Support of modules (reuse of the code)● Driven by the community (100% open source)● Completed tested (PHPUnit, Travis CI)● Packages (pyrus, composer) © All rights reserved.
