Function getModule retrieves the input values for location and temperature and creates a querystring.

Proxy and Response

Once weather.php receives the querystring, it will construct and send an HTTP GET using CURL to retrieve the results from the Yahoo! Weather RSS feed. This allows the transaction to succeed while working around XMLHttpRequest's security policy.

Please enter a U.S. Zip Code or a location ID to get the current temperature. The default is Zip Code 94089 for Sunnyvale, California; its location ID is: USCA1116.

Enter *F* for Fahrenheit or *C* for Celsius temperature unit.
