// -------------------
// LOGIC
// -------------------
// Create the new weather object!
// CIXX0020 = Location Code from weather.yahoo.com
// 3600     = seconds of cache lifetime (expires after that)
// C        = Units in Celsius! (Option: F = Fahrenheit)

$weather_chile = new weather("MKXX0004", 3600, "C", $cachedir);

// Parse the weather object via cached
// This checks if there's an valid cache object allready. if yes
// it takes the local object data, what's much FASTER!!! if it
// is expired, it refreshes automatically from rss online!
$weather_chile->parsecached(); // => RECOMMENDED!

// allway refreshes from rss online. NOT SO FAST.
//$weather_chile->parse(); // => NOT recommended!

//============================================================================
//============================================================================
// Script:        PHP Class "weather"
// Version:     2.0 / 12.12.2006
//
// Rewritten: Dec 2006 by Matt Brown
//   fixed all PHP warnings
//   added cachedir parameter
//   changed structure of results
//   more adaptive to changes in Yahoo RSS feed
//============================================================================
// From:    http://www.voegeli.li
// Autor:    Marco Voegeli, Switzerland >> www.voegeli.li >> fly forward! >>
// Date:    28-Oct-2005
// License/
// Usage:    Open Source / for free
//============================================================================
// DEPENDENCIES:
// -  It requires the class "xmlParser" (Be lucky: Also in the Archive file!)
//============================================================================
// DESCRIPTION:
// This Class gets Weather RSS from WEATHER.YAHOO.COM and parses it into
// a weather object with usable attributes. Use it for:
//
// - Actual Situation (temperature/sunrise/sunset/Image...)
// - Forecast Day 1 (temp low, high/text/date/day/image...)
// - Forecast Day 2 (temp low, high/text/date/day/image...)
//
// PUBLIC METHODS
// - parse() :        Gets the XML File parses it and fills attributes
// - parsecahed() :     Much quicker!!! Writes a cached version to a local
//                file with expiry date! expiry date is calculated
//                with the given input parameter
//
//============================================================================
// SAMPLE:
// - See the file "weather.test.php" in this archive for Santiago de Chile
//
// WEB GUI URL: http://weather.yahoo.com/forecast/CIXX0020_c.html?force_units=1
// RSS URL:     http://xml.weather.yahoo.com/forecastrss?u=C&p=CIXX0020
//
// The class needs one Attribute in the Constructor Method:
//
// $weather_chile = new weather("CIXX0020", 60);
//
// "CIXX0020" is the Yahoo code for Santiago de Chile. See WEB GUI URL above!
//
// "60" means 60 seconds until the cache expires. If not needed set = 0.
//
// GO TO WEATHER.YAHOO.COM and search for your desired weather location. If
// found, click on the location link (must see the forecast). Now take
// the code from the URL in your browsers address field.
//
//============================================================================
// Changes:
// - 19.11.2005 MAV : XML Feed Structure from Yahoo changed. Adapted script.
//============================================================================
// Visit http://dowdybrown.com , the contributor of the new version. Thank you
// Matt for this great and better version of the yahoo weather class! You have
// done a good job!
