PHP - Simple Paging System

[Master Jake]

This is a paging system I wrote a long time ago. Keep in mind that this will generate as many links as there are pages at a time. So if you only want the last 3, current, and next 3 pages generated or something like this, don't use this code. That is a separate paging system that I wrote, but am not releasing right now because it looks too messy.
