</HotelListing>

现在我想从中获取房间数据，我的代码是 $response 是 xml 字符串的地方：

 private function hotelDetailsResponse($response)
    {
       $data = [];

        $dom = new \DOMDocument();
        $dom->formatOutput = TRUE;
        $dom->preserveWhiteSpace = FALSE;
        $dom->loadXml($response);

        $Rooms = $dom->getElementsByTagName( "Room" );
        foreach( $Rooms as $Room ) {

            $names = $Room->getElementsByTagName("RoomTypeName");
            $data[] = $names->item(0)->nodeValue;
            $types = $Room->getElementsByTagName("RoomTypeCode");
            $data[] = $types->item(0)->nodeValue;

            }

           return $data;
    }

它给了我这样的数组：

["Deluxe Cottage AC","45000001713","Den Cottage AC","45000001714","Premium Cottage AC","45000001715","Couple Package  Deluxe Non AC","45000012484","Couple Package for Den AC Room","45000012503","Couple Package for PREMIUM AC ","45000012507"]

我需要这样的数组：

[{"Name":"Couple Package for PREMIUM AC ","Code":"45000012507"}, {"Name":"Couple Package for PREMIUM AC ","Code":"45000012507"}, {"Name":"Couple Package for PREMIUM AC ","Code":"45000012507"}]

我也尝试像这样在 foreach 中给出值：

$Rooms = $dom->getElementsByTagName( "Room" );
foreach( $Rooms as $Room ) {

    $names = $Room->getElementsByTagName("RoomTypeName");
    $data['name'] = $names->item(0)->nodeValue;
    $types = $Room->getElementsByTagName("RoomTypeCode");
    $data['code'] = $types->item(0)->nodeValue;

    }

但它只给我最后一个参数，如下所示：

{"name":"Couple Package for PREMIUM AC ","code":"45000012507"}

请帮忙....

【问题讨论】：

你能把你的问题简化为一个更简洁的例子吗？很多关于如何提出好问题的方法包括提出minimal, complete and verifiable example。对于有类似问题的其他用户来说会更好，并且更容易回答。

标签： php xml foreach

【解决方案1】：

您正在获取名称和类型，并将它们放入同一个数组中：

$names = $Room->getElementsByTagName("RoomTypeName");
$data[] = $names->item(0)->nodeValue;
$types = $Room->getElementsByTagName("RoomTypeCode");
$data[] = $types->item(0)->nodeValue;

减少，看起来像这样：

$data[] = $name;
$data[] = $type;

您需要做的是将这些作为关联数组添加到$data 数组中。这是一种声明方式：

$data[] = [
    'Name' => $names->item(0)->nodeValue,
    'Code' => $types->item(0)->nodeValue
];
