I'm trying to create a database using composer. I've demo.php as the main file and running the code on localhost.
Error message :
Fatal error: Uncaught
MongoDB\Driver\Exception\ConnectionTimeoutException: No suitable
servers found (serverSelectionTryOnce set): [socket timeout calling
ismaster on '127.0.0.1:27017'] in
C:\xampp\htdocs\phpmongodb\vendor\mongodb\mongodb\src\Database.php:201

in C:\xampp\htdocs\phpmongodb\vendor\mongodb\mongodb\src\Database.php
on line 201
What could be the reason for this?
My code:
<?php
require 'vendor/autoload.php';
$client = new MongoDB\Client;
$companydb = $client->companydb;
$result1 = $companydb->createCollection('emplcollection');
var_dump(result1);
?>

require_once DIR . '/vendor/autoload.php';
