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


A new core

● The ZF1 way:

▶ Singleton, Registry, and Hard-Coded Dependencies

● The ZF2 approach:

▶ Aspect Oriented Design and Dependency Injection


MVC is event driven

● Everything is an event

dispatchbootstrap route

Listeners


Releases

● ZF2.0.0beta4

● Goal:

▶ beta5 at the end of June▶ ZF 2.0 RC this summer!!!


Quick startZend Skeleton Application


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

Zend\ServiceManager

● 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


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)


module


A module is all related code and assets that solve a specific problem.

Modules inform the MVC about services and event listeners

Modules by default


Modules for ZF2

● The basic unit in a ZF2 applicationis a Module

● Modules are “Plug and play” technology● Modules are simple:

▶ A namespace▶ Containing a single classfile: Module.php


Develop Modules

● Modules contain all logic related to a discrete application problem.

▶ Controllers▶ Entities▶ Plugins▶ Etc.

● 99% of the time, you will write modules


\module\Application\Module.php


/module/Application/config/module.config.php(routing part)


/module/Application/config/module.config.php(controller part)


/module/Application/config/module.config.php(view)


/module/Application/src/Application/Controller/IndexController.php

Passing array() of variables to the view


Packaging system


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>

http://packages.zendframework.com/

http://packages.zendframework.com/pyrus.phar


Composer

● New package management and distribution

tool

● http://packagist.org/

● http://getcomposer.org/

http://packagist.org/


composer.json


From ZF1 to ZF2


From ZF1 to ZF2

● Goal: migrate without rewriting much code!

● Main steps

▶ Namespace: Zend_Foo => Zend\Foo▶ Autoloading: 3 options ▶ MVC: module, event based, dispatchable▶ DB: new Zend\Db▶ Form: new Zend\Form

● Can run in parallel (instant migration!)


Conclusion:ZF2 rocks!


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)


We want you!
