Overview of this book

Zend Framework 2 is the latest creation of World Wide Web infrastructure company Zend Technologies Ltd. This new PHP framework comes with tons of features and an attractive way of creating applications. Not only is the overall usability of the technology much better, but it also makes your applications more testable, something that is often overlooked. "Zend Framework 2 Cookbook" will show you how applications are set up in Zend Framework 2 and how you can develop successfully in this massive framework. You will master features like Modules, Views, Controllers, and Authentication. The book also discusses the Event Manager, unit testing, and how to optimize your application. The book begins with a discussion about setting up Zend Framework 2, and you will also look at how the framework itself works. By the end of this book, you will be able to create entire secure applications on your own and make sure they are tested and optimized for performance as well. You will learn about sending and receiving e-mails, translation and localization of the application, and how to set up the framework on a Linux web server. You will also learn how to display data from the application to the user by using different display strategies and renderings. The creation of modules will also be discussed. Then, you will move on to look at how to authenticate users and make sure the developer knows how to pick the best method available. Unit testing, debugging, and enhancing the performance will also be covered in this book. "Zend Framework 2 Cookbook" is a perfect book for anyone who wants to start developing with Zend Framework 2.

Getting ready

A database profiler is used to find bottlenecks in query performance and is a great tool to debug the queries that are executed in a session and of course the time it takes for them to execute. Once we develop bigger applications we tend to forget when and how certain pieces of code execute, which sometimes can lead to unnecessary complexity in our code.

How to do it…

Profiling an application's database usage can give a clear overview on the performance of our application, in this recipe we will discuss how to set up a simple profiler.

Setting up a new profiler

Setting up a new profiler is really easy as at the moment there is only one class in Zend Framework 2 that can be used as...
