Class 'App\Http\Controllers\App\Article' not found Laravel 5.6 - model-view-controller

Question

I have a "basic" problem, but I can't figure where.
I have a problem between the controller and the model.
I went on the Internet and I saw a lot of "Class 'App\Http\Controllers\App{something}' not found" solved problem, but none worked for me.
Could it be because I did a copy-past form my native project?
I'm only looking for the "index" part. I can't work on the rest since I can't see what I'm doing.
MyController:
<?php
namespace App;
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use app\Article;
class ArticleController extends Controller
{
/**
* Display a listing of the resource.
*
* #return \Illuminate\Http\Response
*/
public function index()
{
session_start();
$article = App\Article::Blog();
}
/**
* Show the form for creating a new resource.
*
* #return \Illuminate\Http\Response
*/
public function create()
{
session_start();
// si je reçois des données de formulaire,
if (isset($_POST['titre'], $_POST['description'], $_POST['contenu'])
){
$admin = Add();
// si la création a réussi,
if ($add) {
//rediriger vers
header('location: /Chef/Controleur/controleur-blog.php');
echo "Well done!". '<br>';
echo "You have add an article!";
}
}
else {
// afficher le formulaire
echo "Error. Please try again.";
require __DIR__.'/Controleur/controleur_piedpage.php';
}
}
/**
* Store a newly created resource in storage.
*
* #param \Illuminate\Http\Request $request
* #return \Illuminate\Http\Response
*/
public function store(Request $request)
{
//
}
/**
* Display the specified resource.
*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function show($id)
{
//
}
/**
* Show the form for editing the specified resource.
*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function edit($id)
{
require __DIR__.'/../Modele/modele.php';
$article = Article();
// si je reçois des données de formulaire,
if (isset($_POST['titre'], $_POST['description'], $_POST['contenu'])){
$admin = Edit();
// si la création a réussi,
if ($edit) {
//rediriger vers
header('location: /Chef/Controleur/controleur-blog.php');
echo "You have edit an article!";
}
}
else {
// afficher le formulaire
require __DIR__.'/Controleur/controleur-entete.php';
require __DIR__.'/Controleur/controleur-recherche.php';
require __DIR__.'/../Vue/edit.php';
echo "Error. Please try again.";
require __DIR__.'/Controleur/controleur_piedpage.php';
}
}
/**
* Update the specified resource in storage.
*
* #param \Illuminate\Http\Request $request
* #param int $id
* #return \Illuminate\Http\Response
*/
public function update(Request $request, $id)
{
//
}
/**
* Remove the specified resource from storage.
*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function destroy($id)
{
require __DIR__.'/../Modele/modele.php';
$admin = Delete();
$article = Article();
if ($delete) {
//rediriger vers

}

require __DIR__.'/../Vue/delete.php';
echo "Error. Please try again.";
require __DIR__.'/Controleur/controleur_piedpage.php';
}
}
}
My Model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Article extends Model {
function Blog() {
if(isset($_POST['register'])) if(('role'== 0) && ('role' == 1)) {
$todoread = [];
$pdo = prepareStatement('SELECT * FROM article ORDER BY id DESC LIMIT 100');
$pdo->execute();
$todoread = $pdo->fetchAll(PDO::FETCH_ASSOC);
return $todoread;
}
}
function Edit(){
$pdo_statement = prepareStatement('UPDATE article
SET titre=:titre, description=:description, contenu =:contenu
WHERE id=:id');
$pdo_statement->bindParam(':id', $_GET['id']);
$pdo_statement->bindParam(':titre', $_POST['titre']);
$pdo_statement->bindParam(':description', $_POST['description']);
$pdo_statement->bindParam(':contenu', $_POST['contenu']);
$pdo_statement->execute();
return true;
}
function Article(){
if(isset($_GET['id'])) {
$sql = "SELECT * FROM article WHERE id = :id";
$article = prepareStatement($sql);
$article->bindParam(':id', $_GET['id']);
$article->execute();
return $article->fetch();
}
}
function Delete() {
if (isset($_POST['submit'])) {
$pdo_statement = prepareStatement('DELETE FROM article WHERE id =:id');
$pdo_statement->bindParam(':id', $_GET['id']);
$pdo_statement->execute();
$pdo_statement->fetchAll(PDO::FETCH_ASSOC);
return true;
}
}
function Add(){
if (isset($_POST['submit'])) {
$pdo_statement = prepareStatement(
'INSERT INTO article (titre, description, contenu)
VALUES (:titre, :description, :contenu)');
$pdo_statement->bindParam(':titre', $_POST['titre']);
$pdo_statement->bindParam(':description', $_POST['description']);
$pdo_statement->bindParam(':contenu', $_POST['contenu']);
$pdo_statement->execute();
return true;
}
}
}

To fix your issue, change:
<?php
namespace App;
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use app\Article;
In your controller to:
<?php
namespace App\Http\Controllers; // <- removing duplicate namespace
use Illuminate\Http\Request;
use App\Article; // <- Case sensitive, use App\, not app\
Other than that, I would really encourage you to read the documentation of Laravel, because this code is not really using Laravel.
You do not have to use session_start() as in Laravel you have Session.
You do not have to work with superglobals as $_POST, because you can use Laravel's Request objects.
You should not handle request data in your models, that's what your controller and/or services are for, this layer (request data) should not 'bleed' into your models like this.
You are using PDO statements, and totally bypass Laravel's Eloquent ORM.
I also see a lot of conditional requires, something that you should not do if you were using Laravel's service container.
With all of this, you are practically skipping every bit of functionality of Laravel and you are basically using the entire framework just for routing.
