Google Weather API Widget (PHP) (No longer Working)

Note: Google has killed the free hidden weather API so this method no longer works

The Google Weather API is a hidden service for developers to get weather data for any location with ease.
Indeed, you just simply pass a city name or postal code, such as this Mountain View

Query by City

http://www.google.com/ig/api?weather=Mountain+View   

Query by Coordinates

http://www.google.com/ig/api?weather=,,,30670000,104019996 

To get an XML response like this:

This is the php code to get a widget like shown above. Line 20 defines the location for the widget.
Either you can use postal code, city or coordinates multiplied by 1000000 (Check Line No 21,22,23,25)
