Collection – filter() Method

We will see how to use filter() into collection.

Suppose we have SiteController.php a controller file inside /app/Http/Controllers folder.

Code Example #1

Laravel Collection filter() with multi dimensional array.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class SiteController extends Controller
{
    public function index()
    {
        $students = collect([
            ["id" => 1, "name" => "Sanjay", "email" => "sanjay@gmail.com", "marks" => 88],
            ["id" => 2, "name" => "Vijay", "email" => "vijay@gmail.com", "marks" => 70],
            ["id" => 3, "name" => "Ashish", "email" => "ashish@gmail.com", "marks" => 75]
        ]);

        $passed = $students->filter(function ($value, $key) {
            return data_get($value, 'marks') > 70;
        });

        $passed = $passed->all();

        dd($passed);
    }
}

Concept

$passed = $students->filter(function ($value, $key) {
      return data_get($value, 'marks') > 70;
});

Output

Code Example #2

Laravel Collection filter() with single dimensional array.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class SiteController extends Controller
{
    public function index()
    {
        $data = collect([2, 3, 5, null, false, '', 0, []]);

        $data = $data->filter()->all();

        dd($data);
    }
}

In this case it will remove the false values from array
