  1. Symfony 4 New Features

  2.  Unlike other web frameworks, Symfony is designed as a collection of standalone and reusable components.  It allows developers to add functionality to the web applications and complete common web development tasks by choosing from 50 PHP components.  Also, the open source web framework for PHP has been evolving consistently to simplify development of modern websites and web applications.  The 4th major version of Symfony was released in November 2017.

  3.  Symfony 4 is designed as a lean and micro web framework. Here is an article on Symfony performance compared to other PHP frameworks.  A Symfony 4 application will be much leaner than a Symfony 3 application.  But the latest version of the widely used PHP framework comes with several new features, improvements, and bug fixes.  At the same time, it aims to transform developer experience and make developers build web applications in a new way.  Hence, it becomes essential for PHP programmers to understand the new and improved features provided by Symfony 4.0.

  4. Overview of New and Improved Features in Symfony 4 Symfony Flex  The version 4.0 of Symfony replaces Symfony Installer with Symfony Flex.  Symfony Flex is developed as a robust tool to automate common tasks like installation and uninstalling of bundles and Composer dependencies.  The developers can further avail the tool by default.  They can take advantage of Symfony Flex to install and manage web applications more efficiently.

  5. Symfony Recipes In addition to using Symfony Flex, the PHP programmers also have option to use a set of Symfony recipes. Symfony recipes use Symfony Flex Composer plug-in to automate configuration of Composer packages. The instructions included in these recipes further enable programmers to add a wide range of third-party packages and bundles to the Symfony app.

  6. Improved Dependency Injection Mechanism  Symfony 4 comes with an improved Dependency Injection Component (DIC). The DIC does not require developers to define services one by one.  It now loads automatically.  It even loads individual classes as specific services automatically.  It picks the services automatically by using the classes as identifiers.  The developers can take advantage of the updated dependency injection mechanism to organize code as services and use the service as required.

  7. Much Leaner than Symfony 3  Symfony 4 is designed as the leanest version of the PHP framework. It is designed based on a micro kernel.  A Symfony 4 application will contain about 70% code and files lesser than a Symfony 3 application.  The developers can use the latest version of Symfony to build a variety of web applications without additional dependencies and with reduced footprint.  As a leaner web framework, Symfony 4 will further help developers to speed up and scale websites and web applications.
