Many PHP developers are great specialists and know their way around PHP like the back of their hand. However, when a powerful framework like Symfony is built, it also includes software patterns and designs, which even the most experienced developers need to learn. This book is aimed to teach you exactly that. 

Console applications written in PHP are more and more common: utilities, data parsers, message queue workers, and even system daemons are written in PHP nowadays.

In this book we will talk in detail a couple of Symfony2 components that deal with console applications: the console, the process, the finder and the filesystem component. We talk about how they work internally, and how they can be utilized either from a stand-alone application or framework, or through your own Symfony2 framework application.

An absolute must for those writing console applications or console tasks, and those who want to understand the internals of the console in general.

The Symfony Rainbow Series is a collection of books, which describe, in detail, the different components that make up the Symfony framework. Every book will concentrate on a single component or a set of smaller components. The books will describe the component's inner workings and also give you recipes to solve common problems quickly and efficiently.

These books are intended for PHP developers with any level of knowledge of Symfony, from beginner to expert. They are especially made for those developers, who work with or want to work with Symfony and want to also do their programming with Symfony as smartly and efficiently as possible. If you would like to learn exactly how the inner workings of Symfony function together as a framework or how to use the wide range of Symfony components in a standalone fashion, then these books are for you!
