google analytics api in php website

I am creating a custom reporting website, wh开发者_StackOverflow中文版ere I want to show live data from google analytics and accordingly the data in my website will change. I want it to be automated and dynamic, like whenever the data changes in GA, i want it to be automatically changed in our website, which will be shown to our clients to show the performance of our websites.

I am guessing this can be achieved by some api calling from php, xml returned values and showing those data on our website along with images.

i would appreciate if anyone could give me more info on how to start working on this.

Google Analytics has an official API. They don't seem to have ready-made PHP examples, but the XML sources should be easy to query. Not sure how "live" GA's data is, though - it could be that it is not possible to do stuff live tracking of visitors.
