Does anyone know a good way to unshorten a URL using PHP ? What I mean are tinyurls, bit.ly, etc..

hmmm, maybe can use mysql to store shorturl + long url,

if you are not running a service, why not use .htaccess

You have three choices:

The first is to do it incrementally (ie aaa aab aac and so on adding to the database every time)
The second randomly with a random string generator, and check to see if that has already been taken in your database, and if not add it. Something like my php random string function (http://www.jaygilford.com/php/php-random-string-generator-function/)would be suitable for this method.
The final method is to fill a database with a preset number of urls that are all unique and then select the ones with no url assigned to it for the url

I would insert a unique string to the database for it.
