simplexml_load_string不分析正確

Question

所以，我試圖解析XML和得到一些價值出來的：

$xml = simplexml_load_string(file_get_contents('http://www.bnr.ro/nbrfxrates.xml')); 
    $currency = []; 

    foreach($xml->Body->Cube->Rate as $rate) 
    { 
     $currency[] = [ 
      "name" => $rate["currency"], 
      "value" => $rate, 
      "multiplier" => $rate["multiplier"] 
     ]; 
    } 

    return $currency; 

我的$率變量應該是價格標籤內的值（例如：1.0806 ），而不是它給了我這樣的：

object(SimpleXMLElement)[110] 
    public '@attributes' => 
     array (size=1) 
     'currency' => string 'AED' (length=3) 

Answer 1

$轉換率（串）將工作：

$currency[] = [ 
     "name" => $rate["currency"], 
     "value" => (string)$rate, 
     "multiplier" => $rate["multiplier"] 
    ];
