如何從一個MySQL數據庫獲得xmlrpc響應，如字段名稱作爲數據元素和記錄？

Question

我使用XMLRPC-EPI爲PHP/MySQL爲基礎的網站，web服務的工作，我得到XML-RPC客戶端respaonse象下面這樣：

opening socket to host: comingsoon.com, port: 80, uri: /CM_server.php 
sending http request: 
POST /CM_server.php HTTP/1.0 
User-Agent: xmlrpc-epi-php/0.2 (PHP) 
Host: fn24dev.com:80 Content-Type: text/xml 
Content-Length: 117 
<?xml version="1.0" encoding="iso-8859-1"?> 
<methodCall> 
<methodName>listVideos</methodName> 
<params/> 
</methodCall> 
receiving response... 
got response: 
<?xml version="1.0" encoding="iso-8859-1"?> 
<methodResponse> 
<params> 
<param> 
    <value> 
    <array> 
    <data> 
    <value> 
     <struct> 
     <member> 
     <name>0</name> 
     <value> 
      <string>63</string> 
     </value> 
     </member> 
     <member> 
     <name>indexer</name> 
     <value> 
      <string>63</string> 
     </value> 
     </member> 
     <member> 
     <name>1</name> 
     <value> 
     <string>02_CHIMPPANTS_24-03-2012_04-43-06</string> 
     </value> 
     </member> 
     <member> 
     <name>video_id</name> 
     <value> 
     <string>02_CHIMPPANTS_24-03-2012_04-43-06</string> 
     </value> 
     </member> 
     <member> 
     <name>2</name> 
     <value> 
     <string>mp4</string> 
     </value> </member> 
     <member> 
     <name>type</name> 
     <value> 
     <string>mp4</string> 
     </value> 
     </member> 
    </struct> 
    </value> 
    </data> 
    </array> 
</value> 
</param> 
</params> 
</methodResponse> 

在這方面，我得到兩個MySQL表的字段名和字段值作爲XML文字內容。但我想獲得像mysql字段名一樣的響應作爲元素和字段值作爲文本內容。如下圖所示，

<member> 
     <indexer>63</indexer> 
</member> 

<member> 
     <video_id>02_CHIMPPANTS_24-03-2012_04-43-06</video_id> 
</member> 
<member> 
    <type>mp4</type> 
</member> 

我添加PHP代碼& MySQL表和數據澄清。

Table_name: videos 
    indexer  video_id       type 
    --------  ---------------------------------- ----- 
    63   02_CHIMPPANTS_24-03-2012_04-43-06  mp4 
    54   02_Friday_23-03-2012_05-11-18   mp4 

CM_server.php

<?php

$connect = mysql_connect("localhost","root","");

} 

//Get the Videos 
function getVideos(){ 
//connect database 
Connect(); 
$videoquery = mysql_query("select * from videos"); 
    if(mysql_num_rows($videoquery) == "0"){ 
     $returnquery = "0"; 
    } else { 
     while($getquery = mysql_fetch_array($videoquery)){ 
      $returnquery[] = $getquery; 
     } 
    } 
    return $returnquery; 
} 
//server creating and check a list a method 
$request = $HTTP_RAW_POST_DATA; 
if (!$request) $request_xml = $HTTP_POST_VARS['xml']; 
$server = xmlrpc_server_create(); 
if (!$server) die("Couldn't create server"); 
xmlrpc_server_register_method($server, 'listVideos', 'getVideos'); 
$options = array('output_type' => 'xml', 'version' => 'auto'); 
echo xmlrpc_server_call_method($server, $request, null, $options); 
xmlrpc_server_destroy($server);

如果有人知道xmlrpc來獲得這個解決方案，請指導我。

您所要求的結構不會是XML-RPC，因此您將無法使用PHP的XML-RPC擴展來實現它。 XML-RPC Specification定義了響應的精確結構，包括可用的類型。您想要的XML服務類型只需要一個XML解析庫（例如SimpleXML），一些XML創建函數（可能是將PHP數組轉換爲XML格式的字符串的遞歸函數）以及少量在一個URL上支持不同方法的「調度代碼」：

$request_xml = file_get_contents('php://input'); 
$request_sx = simplexml_load_string($request_xml); 
switch ((string)$request_sx->Method) 
{ 
    case 'listVideos': 
     $data = getVideos((string)$request_sx->Params->SearchTerm); 
     $response_xml = generate_xml($data); 
    break; 
} 

header('Content-Type: text/xml'); 
echo $response_xml; 
exit;
