Just manage to install MongoDB and use the tutorial from official doc', got an infinite loading with just this :
<?php
use MongoDB\Client;
// Replace the placeholder with your Atlas connection string
$uri = 'mongodb+srv://dev:[email protected]/?retryWrites=true&w=majority;';
// Create a new client and connect to the server
$client = new MongoDB\Client($uri);
So, I maade some search and found another way to connect. (With "mongodb://dev[...]" instead of "mongodb+srv://dev[...]").
Then tried to reach my collection and use it, but, got this beautiful screen :

My code look like this :
<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
use MongoDB\Client;
// Replace the placeholder with your Atlas connection string
$uri = 'mongodb://dev:[email protected]:27017,ac-ierge80-shard-00-01.iupwzop.mongodb.net:27017,ac-ierge80-shard-00-02.iupwzop.mongodb.net:27017/?ssl=true&replicaSet=atlas-7vhjj9-shard-0&authSource=admin&retryWrites=true&w=majority;';
// Create a new client and connect to the server
$client = new MongoDB\Client($uri);
$collection = $client->jvtracker->users;
$cursor = $collection->find(['_id' => 1]);
I did not managed to display some logs / errors, I don't know what's going on here. I disabled Bitdefender (In cas of firewall conflict), changed nothing.
