Below find an extraction script you mind find useful from a website that provides RSS feed of Weather Conditions around the World
I used this script for some USA zips, hence the URL path .. this if or Malta :
http://rss.wunderground.com/auto/rss_full/global/stations/16597.xml?units=both
16597 is Malta, you can get the RSS feed you need from : http://www.wunderground.com/global/ML.html
( full list : http://www.wunderground.com/global/Region/EU/Temperature.html )
| php: |
echo "<br><br> Current Conditions in : <b>" . $zip ."</b> are : ";
$zip = str_replace (" ", "_", $zip);
$url = "http://rss.wunderground.com/auto/rss_full/NC/".$zip.".xml?units=both";
$xml = simplexml_load_file($url);
$title = $xml->channel->item[0]->title;
//echo $title;
$wind = $xml->channel->item[0]->description;
//echo $wind;
//<title>Current Conditions - 37.0F / 2.8C | Clear - 5:32 AM EST Feb. 8</title>
preg_match_all('/- ([0-9\.].+?)F \/ ([0-9\.].+?)C \| ([a-zA-Z ]+?) -/ ', $title, $match) ;
//print_r ($match);
echo $match[1][0]." Farenheight -=- ".$match[2][0]." Celcius ::: Weather Conditions are : ".$match[3][0];
//<description><![CDATA[Temperature: 37.0°F / 2.8°C | Humidity: 72% | Pressure: 29.69in / 1005.3hPa (Steady) | Conditions: Clear | Wind Direction: NNW | Wind Speed: 0.0mph / 0.0km/h<img src="http://server.as5000.com/AS5000/adserver/image?ID=WUND-00049&C=0" width="0" height="0" border="0"/>]]></description>
$st = strstr($wind, 'Wind Direction: ');
list($windspd,$null) = explode('|',$st);
//echo $windspd;
list($null,$winds) = explode( ': ',$windspd);
//print_r ($windspd);
echo " -=- Wind Direction : ".$winds;
|
This is the output :
| Quote: |
Current Conditions in : ANGIER are : 63.7 Farenheight -=- 17.6 Celcius ::: Weather Conditions are : Clear -=- Wind Direction : NE
|
Hope you find this script useful

Edited the preg_match :
| php: |
preg_match_all('/- (-?[0-9\.].+?)F \/ (-?[0-9\.].+?)C \| ([a-zA-Z ]+?) -/ ', $title, $match) ;
|
This will capture negative temperatures
