Question

我正在尝试从父子表生成XML。这是我想要实现的XML格式。 PHP代码仅适用于一个表。我不知道如何从子表生成XML。我感谢任何帮助。

  <SalesOrder>
    <Sales>
     <SalesOrderNumber>SO43660</SalesOrderNumber>
     <PurchaseOrderNumber>PO18850127500</PurchaseOrderNumber>
     <AccountNumber>3333</AccountNumber>
     <OrderDate>2001-07-01</OrderDate>
     <Details>
       <SalesOrderDetailID>13</SalesOrderDetailID>
       <Name>Road-650 Red, 44</Name>
       <CarrierTrackingNumber>6431-4D57-83</CarrierTrackingNumber>
     </Details>
     <Details>
      <SalesOrderDetailID>14</SalesOrderDetailID>
      <Name>Road-450 Red, 52</Name>
      <CarrierTrackingNumber>6431-4D57-83</CarrierTrackingNumber>
    </Details>
   </Sales>
  </SalesOrder>

这是PHP代码。

$result = mysql_query("SELECT * from table1");

header("Content-Type: application/xml");
echo sqlToXml($result, "SalesOrder", "sales");

function sqlToXml($queryResult, $rootElementName, $childElementName)
{

$xmlData = "<?xml version=\"1.0\" encoding=\"ISO-8859-1\" ?>\n"; 
$xmlData .= "<" . $rootElementName . ">";

while($record = mysql_fetch_object($queryResult))
{ 
    $xmlData .= "<" . $childElementName . ">";
    for ($i = 0; $i < mysql_num_fields($queryResult); $i++)
    { 
        $fieldName = mysql_field_name($queryResult, $i); 
        $xmlData .= "<" . $fieldName . ">";
        if(!empty($record->$fieldName))
            $xmlData .= $record->$fieldName; 
        else
            $xmlData .= "null"; 

        $xmlData .= "</" . $fieldName . ">"; 
    } 
    $xmlData .= "</" . $childElementName . ">"; 
} 
$xmlData .= "</" . $rootElementName . ">"; 
}

这是架构。

SalesOrder Table                              SalesOrderDetail
----------------                              ------------------
SalesOrderNumber Varchar(20)                  SalesOrderDetailID    INT
PurchaseOrderNumber Varchar(20)               SalesOrderNumber      Varchar(20)
AccountNumber       Varchar(20)               Name                  Varchar(30)    
OrderDate           Date                      CarrierTrackingNumber  Varchar(30)

在这两行之间：

} 
$xmlData .= "</" . $childElementName . ">";

添加以下内容：

$detail = mysql_query("SELECT * from table2 WHERE salesordernumber = '".$record->SalesOrderNumber."'");
while ($row = mysql_fetch_object($detail)) { 
   $xmlData .= "<Details>";
   $xmlData .= "<SalesOrderDetailID>" . $row->SalesOrderDetailID . "</SalesOrderDetailID>";
   $xmlData .= "<Name>" . $row->Name . "</Name>";
   $xmlData .= "<CarrierTrackingNumber>" . $row->CarrierTrackingNumber . "</CarrierTrackingNumber>";
   $xmlData .= "</Details>";
}

第一行运行查询以从第二个表中获取数据第二行是返回记录的循环 - 使$row成为每条记录的对象。 while循环中的所有内容都会添加到XML字符串（$xmlData）
