Zend Framework 2 Application Development

By: Christopher Valles

Overview of this book

<p>Zend Framework 2 has a flexible architecture that lets us build modern web applications and web services easily. It also provides an easy-to-use, high quality component library that is designed to be used the way you want. It's easy to get started and produce a powerful and professional looking website with Zend Framework 2 Application Development. Exploring real life applications, we will explore the Zend Framework 2 components, as well as throwing some light on best practices and design concerns faced when building complex MVC applications.Zend Framework 2 Application Development is a hands-on guide to building your application. We will explore the components of this new version of the framework and discover how to use each component, the options available, and how to get the most from each component. Whilst learning everything you need to know, we’ll even create our own social network. We will also learn to engineer an application using an API-centric approach, broadly used today to build applications that work seamlessly on desktops, mobiles and tablets. We will learn how to filter and validate data, interact with databases to retrieve and store data, handle and manipulate file uploads, interact with other websites, deal with spam, and also protect your APIs using OAuth authentication whilst allowing people from all over the world to interact with your application. Zend Framework 2 Application Development is your guide to everything you need to know to build applications of any size for big and small companies alike, whilst using the right components for the job.</p>

There are two ways to bootstrap your ZF2 app. The default is less flexible but handles the entire configuration, and the manual is really flexible but you have to take care of everything.

The goal of the bootstrap is to provide to the application, Zend\Mvc\Application, with all the components and dependencies needed to successfully handle a request. A Zend Framework 2 application relies on the following six components:

  • Configuration array

  • ServiceManager instance

  • EventManager instance

  • ModuleManager instance

  • Request object

  • Response object

As these are the pillars of a ZF2 application, we will take a look at how these components are configured to bootstrap the app.

To begin with, we will see how the components interact from a high perspective and then we will jump into details of how each one works. When a new request arrives to our application, ZF2 needs to set up the environment to be able to fulfill it. This process implies reading configuration files and creating the required...
