What would be a correct structure for my laravel project?

I'm a newbie to PHP and Laravel. Last days i've been playing around and got some code doing what i wanted it to do. The point is that now i have some code in my controller, but i know i should make use of a model.

This is my controller:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class FixturesController extends Controller
{

    /**
     * Update fixtures
     *
     * @return db update all changed fixtures
     */
    public function updateFixtures($comp_id) 
    {
        $fixtarray = \Football::getLeagueFixtures($comp_id)['fixtures'];

        foreach ($fixtarray as $key => $value){
                $fixture = array_flatten($value);
                $fixture_id = intval(substr($fixture[0], 41));
                $competition = intval(substr($fixture[1], 45));
                $homeTeam = intval(substr($fixture[2], 38));
                $awayTeam = intval(substr($fixture[3], 38));
                $date = date('d-m-Y H:i:s', strtotime($fixture[4]));
                $status = $fixture[5];
                $matchday = $fixture[6];
                $homeTeamName = $fixture[7];
                $awayTeamName = $fixture[8];
                $goalsHomeTeam = $fixture[9];
                $goalsAwayTeam = $fixture[10];
                $dbvars = array("fixture_id", "competition", "homeTeam", "awayTeam", "date", "status", "matchday", "homeTeamName", "awayTeamName", "goalsHomeTeam", "goalsAwayTeam");
                $finaldbvars = compact($dbvars);
                \DB::table('fixtures')->where('fixture_id', $fixture_id)->update($finaldbvars);
                echo "updated fixture for " . $fixture_id . "</br>";
        }

    }
}

Now when i run this, it does what i want, it updates the Database, but what would my project look like when i format and place it correctly?

I hope i'm in the right place with this question.

Thanks.

PS. I parse my array from an API
