Yesterday while developing PunBB Twitter extension, Invarbrass of Projanmo Forum helped me by providing some URL shortening snippets for several websites. Those were very simple to use. I am sharing so that it comes to others’ usages.
to.ly
function CompressURL($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://to.ly/api.php?longurl=".urlencode($url));
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_HEADER, 0);
$shorturl = curl_exec ($ch);
curl_close ($ch);
return $shorturl;
}
echo CompressURL("http://projanmo.com");
TinyURL.com
function tinyurl($url) {
$url = "http://tinyurl.com/api-create.php?url=" . $url;
$tinyurl = file_get_contents($url);
return $tinyurl;
}
bit.ly
function make_bitly_url($url,$login,$appkey,$format = 'xml',$version = '2.0.1')
{
//create the URL
$bitly = 'http://api.bit.ly/shorten?version='.$version.'&longUrl='.urlencode($url).'&login='.$login.'&apiKey='.$appkey.'&format='.$format;
//get the url
//could also use cURL here
$response = file_get_contents($bitly);
//parse depending on desired format
if(strtolower($format) == 'json')
{
$json = @json_decode($response,true);
return $json['results'][$url]['shortUrl'];
}
else //xml
{
$xml = simplexml_load_string($response);
return 'http://bit.ly/'.$xml->results->nodeKeyVal->hash;
}
}
/* demo */
$short = make_bitly_url('http://projanmo.com','projanmo forum','R_kdfh84jdjf49jdfjd','json');
echo 'The short URL is: '.$short;
Note: To use bit.ly first register on their site and get api key to use their shortening service.

$original_url = 'http://www.google.com/';
$request = 'http://u.nu/unu-api-simple?url=' . urlencode($original_url);
$response = file_get_contents($request);
if (substr($request, 0, 4) == 'http')
{
echo "Shortened URL = $response";
}
else
{
list ($error_code, $error_message) = explode('|', $response);
echo "Error = $error_message ($error_code)";
}
