    // Or Nothing if you just wanna check for errors 
catch(Exception $e){
    echo "Unable to connect to Database at the moment ! ";

$colecciones = $client->listCollections();
foreach ($colecciones as $col) {
    echo $col->getName();


what i am trying to do here is to make sure that my database connection is successful and also list out the collection name of my mongodb database.

Well, there are some logical error with your code, you can try below code to do this.

require 'vendor/autoload.php'; // Make sure to include the MongoDB PHP library autoload file

$client = new MongoDB\Client('mongodb+srv://'.$_ENV['MDB_USER'].':'.$_ENV['MDB_PASS'].'@'.$_ENV['ATLAS_CLUSTER_SRV'].'/test');

try {
    $databases = $client->listDatabases();
    foreach ($databases as $databaseInfo) {
        echo "Database: " . $databaseInfo['name'] . "\n";
} catch (Exception $e) {
    echo "Unable to connect to the database at the moment!";

$database = $client->selectDatabase('your_database_name'); // Replace with your actual database name
$collectionNames = $database->listCollectionNames();
foreach ($collectionNames as $collectionName) {
    echo "Collection: " . $collectionName . "\n";
