Understand how controllers help organize request handling in Laravel

💡 Why This Matters

🌍 Real World

Web applications often have many pages and actions. Controllers help organize the code that handles these requests, making the app easier to build and maintain.

💼 Career

Understanding how to use controllers is essential for Laravel developers to write clean, scalable, and maintainable web applications.

1

Create the Controller Class

Create a controller class named PageController inside the app/Http/Controllers directory. The class should extend Controller.

Laravel

<?php

namespace App\Http\Controllers;

// Your code here

Need a hint?

Controllers in Laravel are PHP classes inside app/Http/Controllers. They usually extend the base Controller class.

2

Add a Method to Handle the Home Page

Inside the PageController class, add a public method named home that returns the string 'Welcome to the Home Page!'.

Laravel

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;

class PageController extends Controller
{
    // Add the home method below
    // Your code here
}

Need a hint?

Controller methods handle requests and return responses. Here, the home method returns a simple string.

3

Define a Route Using the Controller Method

In the routes/web.php file, define a GET route for '/' that uses PageController@home to handle the request.

Laravel

<?php

use Illuminate\Support\Facades\Route;

// Add the route below
// Your code here

Need a hint?

Routes connect URLs to controller methods. Use the array syntax with the controller class and method name.

4

Complete the Controller Setup

Ensure the PageController class and the route are correctly set up so that visiting '/' returns the welcome message. Confirm the namespace and use statements are correct.

Laravel

<?php

// Verify the controller and route setup is complete
// Your code here

Need a hint?

Controllers keep your request handling organized by grouping related methods. Routes point to these methods to respond to user requests.
