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]);

Example #1 Use first() Method
In this example we will consider a multi dimensional array. We will see how to use first() into collection.
Suppose we have SiteController.php a controller file inside /app/Http/Controllers folder.
<?php 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 = $data->first(); dd($first); } }
Concept
$first = $data->first();
Output
When we execute this code snippet, then we will get something like this –
Example #2 Use firstWhere() Method
We will see how to use firstWhere() into collection.
firstWhere() method indicates that we will use some conditions to get values.
<?php 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");
Output
When we execute this code snippet, then we will get something like this –
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); } }
