To use the script just include it in your files and call the getPageRank() function, passing the URL as the parameter.

Or, you could dig into a code of other plugins that do that, like this one:

WordPress › Show-My-PageRank « WordPress Plugins

and modify it for your needs.

I have it. I did make one last year for personal use. Let me know if you're interested. I can pass it to you.

You can easily find such a script on hotscripts you will get lots of free scripts there

If you use WordPress the use the plugin, it best choice.

Here

Seo Stats Script - PHP Website Ranking Checker Tools

You will not only find pagerank with this script but also have many more advanced features like backlinks, indexed pages etc plus a great looking interface and admin panel.....
