The following example demonstrates how to connect PHP to MySQL using MySQLi in an object-oriented style. It is best practice to create a dedicated database and user for your application rather than using the 'root' account. This approach improves your application's security.

<?php

$hostname = '<XXXXXX>.stackhero-network.com';
$user = 'root';
$password = '<yourPassword>';
$database = 'root'; // In production, create a dedicated database and user in phpMyAdmin

$mysqli = mysqli_init();
$mysqliConnected = $mysqli->real_connect($hostname, $user, $password, $database, NULL, NULL, MYSQLI_CLIENT_SSL);
if (!$mysqliConnected) {
  die('Connection error: ' . $mysqli->connect_error);
}

echo 'Connection successful... ' . $mysqli->host_info . "\n";

$mysqli->close();
