Question Google Related Keywords on searches

I am trying to figure out a way to add the php class onto the phpdig search result pages. This will pull related keywords for a search from google.

Here is a link to the script on my site:
http://www.caribbeanmag.com/phpdig/n...beach%20resort

What's the best way to integrate this?
