Laravel collection remove item by value step
Step 1: Using reject() Method to Remove Item by Value
The reject() method in a Laravel collection is used to filter out elements that match a specific condition. It returns a new collection that contains all the elements that do not meet the condition.
Example
<?php
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class DemoController extends Controller
{
public function index() {
$collection = collect(['red', 'blue', 'green']);
$removeValue = 'blue';
$filteredCollection = $collection->reject(function ($item) use ($removeValue) {
return $item === $removeValue;
});
dd($filteredCollection->toArray());
}
}
Explanation:
- In this example, the reject() method is used to remove the item with value blue from the collection.
- The resulting collection contains all items except for blue.
Output:
array:2 [
0 => "red",
2 => "green",
]2. Using filter() method to remove item by value

{
public function index() {
$collection = collect(['red', 'blue', 'green']);
