Category: PHP Script Codes > Itty Bitty URL Shrinker (For Drupal)
A fairly simple url shrinking application based on a Drupal.org install. This allows for a great deal of flexibility as there are a great many other modules that the script could be associated with.

It checks the database for previous entries with the same url and verifies that the url is valid. This helps make the urls even shorter in the long run.
