Inside this article we will see the use of first() and firstWhere() methods in laravel 9 collections. Article contains a very classified information about the basic concept of Laravel 9 Collection first() and firstWhere().

The 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.

As mentioned above, the collect helper returns a new  Illuminate\Support\Collection instance for the given array.

So, creating a collection is as simple as:

$collection = collect([1, 2, 3]);

Laravel Installation

Open terminal and run this command to create a laravel project.

$ composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

$ php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

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

        $first = $data->first();

        dd($first);
    }
}

namespace App\Http\Controllers;

use Illuminate\Http\Request;

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

        $first = $data->firstWhere("email", "vijay@gmail.com");

        dd($first);
    }
}

Condition

$first = $data->firstWhere("email", "vijay@gmail.com");

Another example for using firstWhere(),

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class SiteController extends Controller
{
    public function index()
    {
        $data = collect([
            ["id" => 1, "name" => "Sanjay", "email" => "sanjay@example.com", "age" => 29],
            ["id" => 2, "name" => "Vijay", "email" => "vijay@gmail.com", "age" => 32],
            ["id" => 3, "name" => "Ashish", "email" => "ashish@sample.com", "age" => 25]
        ]);

        $first = $data->firstWhere("age", ">", 30);

        dd($first);
    }
}
