从其他网站提取货币值

Question

我想从定期更新它们的网站中提取特定货币的值。因为我只需要将欧元兑换成少数外币。这是可能的，或者我应该创建我自己的数据库并更新它？

Answer 1

通过调用这个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]; 
     }  
    } 

我希望这将帮助你:)
