Google recently made an API available for Google Analytics and I create a PHP class for accessing the Google Analytics API with CURL and using DOMDocument to parse the XML. The resulting class can be downloaded here and I covered some of the functions from it in a series of posts.

As I make further changes to the class I will replace that file with the most up to date version.

Feel free to use the class as you wish but if re-posting it on other websites or using it in your own projects or for your customers, please attribute the base work to me and do not try to pass it off as your own.

I have written the following posts about the Google Analytics API and this class:

1. Log into the Google Analytics API using PHP and CURL using Username/Password Authentication (April 23rd 2009)
