Mastering Symfony

Overview of this book

In this book, you will learn some lesser known aspects of development with Symfony, and you will see how to use Symfony as a framework to create reliable and effective applications. You might have developed some impressive PHP libraries in other projects, but what is the point when your library is tied to one particular project? With Symfony, you can turn your code into a service and reuse it in other projects. This book starts with Symfony concepts such as bundles, routing, twig, doctrine, and more, taking you through the request/response life cycle. You will then proceed to set up development, test, and deployment environments in AWS. Then you will create reliable projects using Behat and Mink, and design business logic, cover authentication, and authorization steps in a security checking process. You will be walked through concepts such as DependencyInjection, service containers, and services, and go through steps to create customized commands for Symfony's console. Finally, the book covers performance optimization and the use of Varnish and Memcached in our project, and you are treated with the creation of database agnostic bundles and best practices.

Handling users with FOSUserBundle

This is the best user management bundle so far. It comes with many user management features (such as user registration, edit profile, forgotten password, and others) out of the box. All you need to do is install and activate the bundle and extend your own User entity from it. Let's start with the installation:

$ composer require friendsofsymfony/user-bundle '~dev-master'

Note

At the time of writing this chapter, there are some unresolved issues between Symfony 3 and stable releases of FOSUserBundle that are being fixed on a daily basis. So, if you don't see any stable version greater than or equal to v2.0, make sure that you are using the master branch.

Of course, then we need to activate it:

<?php
// app/AppKernel.php
public function registerBundles()
{
    $bundles = array(
        // ...
        new FOS\UserBundle\FOSUserBundle(),
    );
}

Now we need to modify the current User entity and extend it from this bundle. Get rid of the e-mail, name, and bio...
