this chapter explains how to create a simple application in symfony framework. as discussed earlier, you know how to create a new project in symfony.

we can take an 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.

controller

symfony is based on the model-view-controller (mvc) development pattern. mvc is a software approach that separates application logic from presentation. 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.

studentcontroller.php

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.
