How to convert Google short URLs back to its original URL?

I have some short URLs. How can I get the original URLs from them?.

Solution

  • As the URL-shortener-services are mostly simple redirectors they use the location header to tell the browser where to go to.

    You can use PHP's own get_headers() function to get the appropriate header:

    $headers = get_headers('http://shorten.ed/fbsfS' , true);
echo $headers['Location'];
