具有屬性的JSON序列化和XML

Question

根據請求的內容類型，我有一個需要序列化爲JSON或XML的數組。

$responseArray = [ 
          "name" => "" 
         , "status" => -1 
         , "message" => "An unknown error has occurred." 
        ]; 

用JSON編碼它工作得很好

$plainTextResponse = $serializer->serialize($responseArray, 'json'); 

{"name":"","status":-1,"message":"An unknown error has occurred."} 

哪些是對的，正是我需要的。問題是將其表示爲XML

$plainTextResponse = $serializer->serialize($responseArray, 'xml'); 

<?xml version="1.0"?> 
<response> 
    <name></name> 
    <status>-1</status> 
    <message>An unknown error has occurred.</message> 
</response> 

但是在命令中嵌套這些屬性的intead我需要它們顯示爲屬性。這是可行的這種方式（注意屬性名前的@）

$responseArray = [ 
          "@name" => "" 
         , "@status" => -1 
         , "@message" => "An unknown error has occurred." 
        ]; 

... 

    $plainTextResponse = $serializer->serialize($responseArray, 'xml'); 


<?xml version="1.0"?> 
<response name="" status="-1" message="An unknown error has occurred."/> 

而且很明顯，如果我試圖將其轉換成JSON然後它會留在屬性

$plainTextResponse = $serializer->serialize($responseArray, 'json'); 

{"@name":"","@status":-1,"@message":"An unknown error has occurred."} 

是名稱的@有一種序列化數組的方法，以便它在XML中添加屬性並且在json中沒有@。

我想你應該對XML序列化創建另一個數組：

foreach($responseArray as $key => $value) { 
    $respondeArrayXml["@".$key] = $value; 
} 
$plainTextResponseXML = $serializer->serialize($responseArrayXML, 'xml'); 
$plainTextResponseJSON = $serializer->serialize($responseArray, 'json');
