// database credentials

define('DB_SERVER', 'localhost');

define('DB_USERNAME', 'root');

define('DB_PASSWORD', 'root');

define('DB_DATABASE', 'real_estate');

// new database connection

$db = new mysqli(DB_SERVER,DB_USERNAME,DB_PASSWORD,DB_DATABASE);

// check connection

if ($db->connect_errno) {

die("Connection failed: " . $db->connect_errno);

}
