hey,how can I run this script?Is it for any webpages or some other stuff??( Sorry to ask you such a newbie question! I'm not that much into scripting and all! )

I just looked over the script and I think you could give a description some kind of what page rank it shows? I think it won't work, from where do you get the variable $argc? and where it should check the page rank? by the letters and numbers in the domain? I think it might be just one part of the script? I don't really understand Or it should be used somewhere I don't know? For example if a user will find this post from google search, he won't understand? Or this is just me who does not understand..

This is a Command Line Script.

 

if you save it as pagerank.php, you can open a shell, then run the command

$php pagerank.php

If the scripting get a url parameter from your browser, it will generate a checksum for the url
