Creating a Simple Web Application with Symfony Framework

Creating a Simple Web Application

This chapter explains how to create a simple application in the Symfony framework. As discussed earlier, you know how to create a new project in Symfony.

We can take the example of student details. Let`s start by creating a project named student using the following command.

symfony new student

After executing the command, an empty project is created.


Symfony is based on the Model-View-Controller (MVC) development pattern. MVC is a software approach that separates application logic from presentation. The controller plays an important role in the Symfony Framework. All the webpages in an application need to be handled by a controller.

DefaultController class is located at src/AppBundle/Controller. You can create your own Controller class there.

Move to the location src/AppBundle/Controller and create a new StudentController class.

Following is the basic syntax for StudentController class.


namespace AppBundle\Controller; 
use Symfony\Component\HttpFoundation\Response;  
class StudentController { 

Now, you have created a StudentController. In the next chapter, we will discuss more about the Controller in detail.

Create a Route

Once the Controller has been created, we need to route for a specific page. Routing maps request URI to a specific controller’s method.

Following is the basic syntax for routing.

namespace AppBundle\Controller;  
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route; 
use Symfony\Component\HttpFoundation\Response; 
use Symfony\Bundle\FrameworkBundle\Controller\Controller;  

class StudentController { 
      * @Route("/student/home") 
   public function homeAction() { 
      return new Response('Student details application!'); 

In the above syntax, @Route(‘/student/home’) is the route. It defines the URL pattern for the page.

homeAction() is the action method, where you can build the page and return a Response object.

We will cover routing in detail in the upcoming chapter. Now, request the URL http://localhost:8000/student/home and it produces the following result.
