Need script to get google pagerank

Anyone knows if script to get google pagerank is avaialable. I want source code.

Please don't suggest scripts which are hosted by some other websites and need backlink to them.

If anyone knows how to program one, just let me know and I will try to code it myself.

Thanks

 

Here are a couple of scripts capable of managing that. http://www.googlecommunity.com/scripts/google-pagerank.php and http://www.expertsforge.com/Web-Development/Tutorial-48.asp

 

Maybe this:
http://www.googlecommunity.com/scripts/google-pagerank.php

Looks like it might be customizable and there's a link to the source code on that page.

I use it here:

I hope this helps you $url is the URL for which you need to find PR.

 

very well, as I expected it has to be some call made to google service URL.

But, can anyone explain what does the fuctions GoogleCH, mix do here?

That would be appriciated.

 

It creates the checksum needed to send along with the URL so that Google will give you the PR for that site.

 

Is there any way so that we can incorporate Google API while querying the PR ?

 

anyone else get a 403 forbidden when trying to use the googlecommunity script?

 

Thanks all for pointing in right direction.

I used the script from googlecommunities and modified it to make mambot for mambo/joomla.

Cheers!

 

No.

Are you trying it from a windows server? If so, try it on a *nix server and you'll see different results. Also I don't know if their checksum function is up-to-date.

 

I have gotten a 403 Forbidden response from my Fedora/Firefox box.

 

I think it's the checksum then.

 

Windows server, LOL, dont be daft! What idiot uses windows for a server invironment! Slackware all the way baby!

Anyway, when you say its the checksum, what are you referring to?

 

What's wrong with using a windose server for development? Never for production. The checksum I refer to is the one produced by the google toolbar, that must be sent along with the request for authentication.

 

Here's some source code to a function that will output the pagerank given the URL.
icemelon.com/php/google_pagerank.htm

 

Please help me.

What i must change in this code icemelon.com/php/google_pagerank.htm for calc FUTURE PR ?

Or it will be other code ? (for future pr)

Because Future PR differ from Current PR.
Thanks.

 

<tip> Take out a certain variable from the query string and you'll get some interesting XML data. </tip>

BTW - all PR checking tools, I believe (including the one i've developed) - are against G's terms and conditions. I keep holding on hoping i'm wrong - so could someone please enlighten me?

 

well since there is no api for pr the data would need to be scraped of course.

btw I have http://www.shoemoney.com/serps.php if anyone wants source lemme know.
