從其他網站提取貨幣值

Question

我想從定期更新它們的網站中提取特定貨幣的值。因爲我只需要將歐元兌換成少數外幣。這是可能的，或者我應該創建我自己的數據庫並更新它？

通過調用這個XML http://themoneyconverter.com/rss-feed/EUR/rss.xml

$url = "http://themoneyconverter.com/rss-feed/EUR/rss.xml"; 
      $cont = file_get_contents($url); 
      $xml = new SimpleXMLElement($cont); 
$feeds = "AED/EUR"; //// currency rate for United Arab Emirates Dirham 
        ///// You can use it as session 
     foreach ($xml->channel->item as $xml2){ 
      if ($xml2->title==$feeds){ 
      $xml2->description."<br>"; 
      preg_match('/([0-9]+\.[0-9]+)/', $xml2->description, $matches); 
      $rate = $matches[0]; 
     }  
    } 

我希望這將幫助你:)
