Considering the number of URL Shortening services, I decided to make a short review of the subject. URL Shorteners were made popular by micro-blog services which used limited number of characters for a message e.g. Twitter.
So, here’s what’s covered:
Reorganized code. It’s now divided into classes, easier for understanding and reuse. Using PDO for database connection instead of mysql methods. Added QR Code for generated shortlinks. This tutorial won’t change anymore, since it’s on the basic level it needs to be. For more information, you can follow the URL Shortening project I started, named BooRL.
