$link = new MySQLi(
    $server_name,
    $username,
    $password
);

if ($link->connect_error)
{
    die("Could not connect to $name database server: " . $link->connect_error);
}

if (!$link->select_db($db_name))
{
    die("Could not find $db_name database");
}

$link->real_query("DELETE FROM table WHERE row = 123");
