如何更改laravel显示的数据库内容的日期格式

Question

this is my code :

<?php 

namespace App\Http\Controllers; 

use Illuminate\Http\Request; 
use App\Article; 


class ArticleController extends Controller { 

    public function show($id){ 

        $article=Article::findOrfail($id); 

        return view('article', ['article' => $article]); 
    }

    public function list() {

        $articles=Article::all();

        return view('articles', ['articles'=>$articles]);
    } 

 }

and this is the date forming code but i don't know where to paste it, in my code:

date('d-m-Y', strtotime($articles->from_date));
