PHPC6 | Web Development with Silex

  • This two days training course is the best started point for PHP developers who want to improve their knowledge in object oriented PHP web development and want to learn how modern full stack frameworks work. Silex is a microframework built around the Symfony components that enables any PHP developers to build their PHP applications on top of it using an object oriented approach. Thanks to its very lightweight kernel and many extensions, you will discover how to create modern full featured web applications using third party libraries like the Symfony components or Twig templating engine.
  • Prerequisites

    Good knowledge of the PHP language and object oriented programming.
  • Goals

    In two days, this training course enables you to get started with the famous Silex microframework built on top of the Symfony components. You will learn how Silex is designed and develop a real full featured MVC PHP application including HTTP caching, forms and validation, urls routing and database management. This course will also introduce some of the best practices in web development such as automated testing (unit and functional tests) with PHPUnit, clean code programming (dependency injection) and templating with Twig.
