why i can't use the "administration command" in php when i am working in mongoDB

[sashavalentina]

Fatal error: Uncaught Error: Call to undefined method MongoDB\Driver\Manager::listDatabases()

this error keep showing when i wanted to use the administration command for mongodb using php. I do not know whats the problem here and someone with kind soul please help me. The following codes is what i have tried which cause that error.

 

<?php
$client =  new MongoDB\Driver\Manager(  'mongodb+srv://'.$_ENV['MDB_USER'].':'.$_ENV['MDB_PASS'].'@'.$_ENV['ATLAS_CLUSTER_SRV'].'/test'
 );
try{ 
    $dbs = $client->listDatabases(); 
    echo '<pre>';
    print_r($dbs);
    echo '</pre>';
    // Or Nothing if you just wanna check for errors 
}
catch(Exception $e){
    echo "Unable to connect to Database at the moment ! ";
    exit();
}

$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.

Why do you think that MongoDB\Driver\Manager has a method named "listDatabases"? I don't see it.

You are using the low level driver.  You want to use the mongo client library which does have that method.

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

<?php
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!";
    exit();
}

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

Thanks
