Zizim is a URL shortener, written in PHP. This code hasn't been optimised, it's mainly been tidied up from the original codebase which I wrote a few years ago.
The general purpose of this code, is to generate a shortened URL. You parse in a URL (and optionally an alias) and it provides you with a shortened version. Similar to bit.ly and tinyurl.
The script captures basic click information, however this data isn't being utilised as of yet.
I've re-written Zizim using OOP principles, the new code is in a new repository named Zizim OOP, visible here.
