Basic database configuration using the MySql Object

<?php

// PHP databse config file for easy reusability

$hostname = "localhost";        // Hostname to connect with
$username = "username";         // Username for database
$password = "password";         // Password for database

// Create new object for the database connection and store it in a variable
$conn = new mysqli($hostname, $username, $password);

// If the connection is unsuccessful
if (!$conn) {
    // Terminate the script
    die ("Connection failed: " . $conn->connect_error);
}

// Use database school
mysqli_query($conn, "USE school");
