Try a search on google, there are plenty of solutions around.

Here is one I just found;
Page Rank Code: free PHP script for Google PageRank

Careful or the Big G might slap you


Google Terms of Service
Google TOS:

Just wondering if anyone had any luck with this?

The one listed above doesn't work with the new PageRank system. It works for some URL's but not all.

Google mate dozens out there

Thanks for that, Ankit.

The old scripts, the ones that dominant google, no longer work (anything pre-September 2009). That is why it is hard to find a working one. Some work for some URLs but not others.

I managed to find one in an open source SEO package so just extracted the code from there.

The code will posted doesn't work, The conclusion I have is that the checksum function in that code is wrong or invalid. Ayone willing to share a working php script that checks PR, I need this to finish my directory submission tracker tool.

You can get the one used by phpld

If you post in the phpLD forums, we will be happy to help. We do have some tools. Unfortunately, we don't just offer public downloads for things like this as you certainly have to follow some procedures to make sure you do it in a way that is not going to directly violate the google TOS. There are actually some methods we have found that seem to be in compliance, but we do prefer to discuss them on the phpLD forums.

Hi,

This one works: Website Rankings Checker and Tool. Page Rank, Alexa, Backlinks, Bookmarking sites

There is a link at the bottom of the page if you want to download a copy of the script.

Best,

Vic

this one is my favourite.. it does a bit more than just get the PR.

www.getrank.org

there is a link for free pr script on the home page

This one works for me: Google Page Rank Checker (SEO, pagerank, page rank, Ranks) - PHP Classes. I've got it setup running on a rotating proxy to monitor pagerank on hundreds of domains.
