Posting sensor value to a web page

Hiya,
I've got my Arduino connected to some temp sensors and a WiShield.
What is the best method for getting the sensor data on a web page?
I know HTML, Javascript, but am a beginner at PHP.

I want to end up with a personalized weather page using my sensor values . What is the best way to get my live data into a web page?
Is it to POST to a PHP page?

Any help is appreciated.

Thanks!
