Question

我正在尝试从数组中获取来自foreach循环的xml文件，但我在xml文件中只获得了1行。

还有另一种方法可以将数组数据转换为这种格式的xml文件吗？

PHP：

$item = array();
        $item[] = array('CityId'    => $row['city_id'],
                        'StateId'   => $row['state_id'],
                        'CityName'  => $row['city_name']
                        );

        $break = "<br />";
        $quote = '"';
        $xml = "<data>"."\n";
        foreach($item as $_item) {

            echo $xml .= "<city CityId=$quote" . $_item['CityId'] . "$quote StateId=$quote" . $_item['StateId'] . "$quote CityName=$quote" . $_item['CityName'] . "$quote />\n";

        }
        $xml .= "</data>";
        $sxml = new SimpleXMLElement($xml);
        echo $output = $sxml->asXML("data.xml");

输出data.xml：

<data>
<city CityId="1" StateId="217" CityName="New York" />
<city CityId="2" StateId="218" CityName="New Jersey" />
</data>

感谢任何帮助。

数据：

 $cities = array(
        array(
            'cityId' => 1,
            'stateId' => 217,
            'cityName' => 'New York'
        ),
        array(
            'cityId' => 2,
            'stateId' => 0,
            'cityName' => 'Paris'
        ),
    );

这：

$xml = new SimpleXMLElement('<data/>');
foreach ($cities as $key => $city)
{
    $xml->city[$key]['cityId'] = $city['cityId'];
    $xml->city[$key]['stateId'] = $city['stateId'];
    $xml->city[$key]['cityName'] = $city['cityName'];
}

或（更好）：

xml = new SimpleXMLElement('<data/>');
foreach ($cities as $cityData)
{
    $city = $xml->addChild('city');
    $city->addAttribute('cityId', $cityData['cityId']);
    $city->addAttribute('stateId', $cityData['stateId']);
    $city->addAttribute('cityName', $cityData['cityName']);
}

将输出：

<data>
    <city cityId="1" stateId="217" cityName="New York" />
    <city cityId="2" stateId="0" cityName="Paris" />
</data>
