// define your settings
$domain = "example.com";
$user = "dblogin";
$pass = "dbpassword";
$schema = "dbname";

// check to see where this is being loaded from
if ($_SERVER['HTTP_HOST'] == "$domain" || $_SERVER['HTTP_HOST'] == "www.$domain") {
	// if loaded off website, connect to localhost
	$link = mysqli_connect("localhost", $user, $pass, $schema) or die(mysqli_error());
} else {
	// otherwise you will need to access it remotely
	$link = mysqli_connect($domain, $user, $pass, $schema) or die(mysqli_error());
}

// check your connection
if (mysqli_connect_errno()) {
	printf("Connect failed: %s\n", mysqli_connect_error());
	exit();
}

This works great because you have have the exact same files on both servers, when you deploy changes to the site you don’t need to worry about removing your development server info.
