can't get id from url with $_GET[url] in mvc architecture - php

Question

I'm trying to make my own MVC Architecture and i'm stuck on getting id from url.
For example in the url, I have http://localhost/EdelweissMagazine /articles/edit/?id=66
but when I call print_r($_GET[url]) I only have
Array
(
[url] => articles/edit/
[id] =>
)
I can't understand why..
Here is my code. I hope you could help me to understand.
For explanations, I would like to make an update method : When clicking on the edit button, placed inside a photo (only if it is a user), the user goes to a form with datas already written to edit.
Thank you in advance
.htaccess
RewriteEngine On
RewriteRule ^([a-zA-Z0-9\-_\/]*)$ index.php?url=$1&id=$2 [NC,L]
I've used in the router that function index.php
call_user_func_array([$controller, $action], $url);
controller/Articles.php
class Articles extends Controller{
public function index(){
$article = $this->loadModel('Article');
$articles = $article->getAll(); //getAll() : $sql="SELECT * FROM ".$this->table;
$this->render('index', ['articles' => $articles]);
}
public function edit(){
print_r($_GET);
}
}
Views/articles/index.php
<section class="gallery">
<?php
$articleLength = count($articles);
$count = 1; ?>
<?php while($count < $articleLength): ?>
<?php
if($count%4 == 1){
?>
<div class="column">
<?php
}
?>
<div class="wrap-img">
<img class="items-gallery"
src="<?php echo htmlspecialchars(SCRIPT_ROOT.'/'.$articles[$count]['picture'], ENT_QUOTES); ?>"
alt="<?php echo htmlspecialchars($articles[$count]['title'], ENT_QUOTES);?>"
/>
<?php
/*************** Code to edit an article ***************/
if(isLogged()) {

<?php
}
