So i just bought a Microsoft azure SQL server, and im trying to connect to it using php on my website however it keeps throwing an error saying "Warning: mysqli::__construct(): php_network_getaddresses: getaddrinfo failed: No such host is known. in C:\xampp\htdocs\Website\data.php on line 50
Warning: mysqli::__construct(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: No such host is known. in C:\xampp\htdocs\Website\data.php on line 50 Connection failed: php_network_getaddresses: getaddrinfo failed: No such host is known." Can someone give me precise instructions on how to fix this issue.

//echo implode(" ",$stuff);
require_once('vendor/autoload.php');
$stripe = new \Stripe\StripeClient(
  'APIKEYHERE'

if(!empty($stripe->customers->all(['email' => $email, 'limit' => 1])->data[0])){
$yo = $stripe->customers->all(['email' => $email, 'limit' => 1])->data[0]->id;
echo("You are already in our system your customer ID is: " . $yo);

else{

  $stripe->customers->create([
