PHP Class Create Short URL via TinyURL, Is.gd, Hex.io, Tr.im & Bit.ly API
Short URL is commonly used today for several reasons: avoid url garbling, take smallest space especially for long url which need to be posted at limited space format eg: twitter, also often used to manipulate user for specific purposes eg: hiding orginal url for phising and ads/affiliation links.
There are many websites that provide shortening url services, tinyurl, bit.ly, hex.io are some of them, and as addition to my simple twitter, plurk and facebook api implementation, i have created a PHP script to create short url on the fly, currently support: tinyURL, bit.ly, is.gd, tr.im and hex.io, but you can easily add other providers.

Sample of usage:
<?php $url = 'http://www.chazzuka.com/blog/?p=192'; echo ShortUrl::create($url,'trim'); echo '<hr />'; echo ShortUrl::create($url,'tinyurl'); echo '<hr />'; echo ShortUrl::create($url,'isgd'); echo '<hr />'; echo ShortUrl::create($url,'hexio'); echo '<hr />'; echo ShortUrl::create($url,'bitly','your_user_name','your_api_key'); ?>
