💼 Career

Understanding config files and accessing them is essential for Laravel developers to build flexible and maintainable applications.

1

Create the blog config file

Create a config file named blog.php inside the config directory with the following exact array keys and values: 'title' => 'My Laravel Blog', 'posts_per_page' => 5, and 'comments_enabled' => true.

Laravel

<?php

return [
    // Your config settings here
];

Need a hint?

Remember, Laravel config files return an array of key-value pairs.

2

Add a controller method to access config

In a controller named BlogController, create a public method called settings that will access the config values using config('blog.title'), config('blog.posts_per_page'), and config('blog.comments_enabled').

Laravel

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class BlogController extends Controller
{
    // Your code here
}

Need a hint?

Use Laravel's config() helper to get values from your config file.

3

Return config values as an array

Inside the settings method of BlogController, return an array with keys 'title', 'posts_per_page', and 'comments_enabled' set to the respective config values you accessed.

Laravel

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class BlogController extends Controller
{
    public function settings()
    {
        $title = config('blog.title');
        $postsPerPage = config('blog.posts_per_page');
        $commentsEnabled = config('blog.comments_enabled');

        // Your code here
    }
}

Need a hint?

Return an associative array with the config values as keys and variables as values.

4

Add route to access settings method

In the routes/web.php file, add a route that responds to /blog/settings URL and uses BlogController@settings to return the config settings.

Laravel

<?php

use Illuminate\Support\Facades\Route;

// Your code here

Need a hint?

Use Laravel's Route::get() method with an array to specify the controller and method.
