Hello Friends,

In this tutorial, we will go over the demonstration of laravel removing an element by key in a collection. This article will give you a simple example of laravel remove by key an item from the collection. I want to share with you the laravel collection remove by key item code example. We will look at an example of a laravel collection remove an item by key. We are here, to create a basic example of how to remove an element by key from a collection in laravel.

You can use this example with the versions of laravel 6, laravel 7, laravel 8, and laravel 9.

You have just to follow the below step and you will get the layout as below:

Step 1: Install Laravel

This is optional; however, if you have not created the laravel app, then you may go ahead and execute the below command:

composer create-project laravel/laravel example-app
Step 2: Create Format Route web.php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\RemoveByKeyController;

| Web Routes
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!

Route::get('/index',[RemoveByKeyController::class, 'index']);
Step 3: create RemoveByKeyController

we will create RemoveByKeyController. so you can see the below code with output:

php artisan make:controller RemoveByKeyController

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class RemoveByKeyController extends Controller
     * The attributes that are mass assignable.
     * @var array
    public function index()
        $collection = collect(['a' => 'Doe', 'b' => "John" , 'c' => "Gadas" , 'd' => "Maxy"]);

        $selected = ["b"]; 

        foreach ($collection as $key => $value) {
            if ($selected['0'] == $key) {
                $selected = $value;

Step 4: Start Development Server

Start the development server. Use the PHP artisan serve command and start your server:

php artisan serve

Now you are ready to run our example so run the below command to quick run.

#items: array:3 [▼
    "a" => "Doe"
    "c" => "Gadas"
    "d" => "Maxy"

I hope it can help you...
