Hi Friends,
I am going to explain you example of filter() method in laravel 8 collections , You will learn contains a very classified information about the basic concept of Laravel 8 Collection filter(). We will see the concept of filter item into laravel collection. We will filter data into single dimensional array, multi dimensional array.
We will use Illuminate\Support\Collection class provides a fluent. convenient wrapper for working with arrays of data. For example, check out the following code. We’ll use the collect helper to create a new collection instance from the array.
Let's see bellow example:
Step : 1 - Installation of Laravel Application
Use this command then download laravel project setup :
composer create-project --prefer-dist laravel/laravel blog
Collection – filter() Method
We will see how to use filter() into collection.
Suppose we have CollectionController.php a controller file inside /app/Http/Controllers folder.
Laravel Collection filter() with multi dimensional array.
Step : 2 - Create Controller
php artisan make:controller CollectionController
app/Http/Controllers/CollectionController
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class CollectionController extends Controller
{
public function index()
{
$students = collect([
["id" => 1, "name" => "Piyush", "email" => "piyushkamani@gmail.com", "marks" => 88],
["id" => 2, "name" => "Pratik", "email" => "pratik@gmail.com", "marks" => 70],
["id" => 3, "name" => "Nikhil", "email" => "nikhil@gmail.com", "marks" => 75]
]);
$passed = $students->filter(function ($value, $key) {
return data_get($value, 'marks') > 70;
});
$passed = $passed->all();
dd($passed);
}
}
Output:
array:[
0=>array:4[
"id"=>1
"name"=>"Piyush"
"name"=>"piyushkamani@gmail.com"
"mark"=>88
]
1=>array:4[
"id"=>3
"name"=>"Nikhil"
"name"=>"nikhil@gmail.com"
"mark"=>75
]
]
I hope it will help you...
