Can't find any good examples for PR calculations.

Are you trying to create your own algorithm to rank pages, or just retrieve Google's PageRank?

Yeah I want to know how to calculate googles PR. Like some sites use.(I just can't find a good tutorial or article about it.)

Googles PR algorithm is strictly top secret. All of the other sites just feed off the PR that Google reports. Just search for "Google Pagerank API" and you will find it.

The code I made is only licensed to my client but I'll let you know that I had to do a LOT of research to find the CURRENT working pagerank algorithm. A hint can be grabbing the pagerank from google toolbar.

Great article above, i have used it to create my own pagerank algorithm in the past.

And @ Haris -> its impossible to know Google's CURRENT algorithm....

Oh yea, pardon me. I mean the checksum is hard to calculate but once if you get it, you can easily query google toolbar and get the pagerank.
