Adding http://www to url

How can I add http://www to url in an elegant way? I could do a few if statements, but I prefer something neat.

The idea is to create a function addHttpWWW that returns the following, for the inputs below:

google.com => http://www.google.com
http://www.google.com => http://www.google.com
www.google.com => http://www.google.com
http://google.com => http://www.google.com

$input = "google.com";   //Or whatever you want.

$output = "http://www." + str_replace(array("http://www.", "http://", "www."), "", $input);

$url = preg_replace('#(?:http(s)?://)?(?:www\.)?(.+)#', 'http\1://www.\2', $url);
