How to access array data declared in one controller in another controller?

Question

I have an array with some data in a controller, something like this:

$data['countries'] = array(
    ["code" => "fr","title" => "French", "flag" => "https://www.makkumbeach.nl/img/flag_fe.gif"], 
    ["code" => "es","title" => "Spain", "flag" => "https://www.eurojobs.com/templates/Eurojobs/main/images/flags/Spain.gif"]
);

The problem is that I need this array inside another controller. Is there a simple solution for that? Instead of copying the data twice.

Answer 1

Use traits.

<?php

namespace App\Http\Controllers\Traits;

use App\Services\ArticleService;

trait CountriesDataTrait
{
    public function addCountriesData(&$data = [])
    {
        $data['countries'] = array(
            ["code" => "fr","title" => "French", "flag" => "https://www.makkumbeach.nl/img/flag_fe.gif"],
            ["code" => "es","title" => "Spain", "flag" => "https://www.eurojobs.com/templates/Eurojobs/main/images/flags/Spain.gif"]
        );
        return $data;
    }
}

Use Trait in Controllers

<?php

namespace App\Http\Controllers;

use Illuminate\Routing\Controller;
use App\Http\Controllers\CountriesDataTrait;

class FirstController extends Controller
{
    use CountriesDataTrait;

    public function method()
    {
        $data = [
            // some data
        ];
        $data = $this->addCountriesData($data);
        // your logic 
    }
}

Use same trait secondController

<?php

namespace App\Http\Controllers;

use Illuminate\Routing\Controller;
use App\Http\Controllers\CountriesDataTrait;

class SecondController extends Controller
{
    use CountriesDataTrait;

    public function method()
    {
        $data = $this->addCountriesData();
        // your logic 
    }
}
