使用PHP从URL获取XML数据

在PHP中使用XML的新手。下面的示例是针对类似问题的前一个问题给出的解决方案，应该可以正常工作。我没有在加载页面时出现任何PHP错误，但是，我没有看到任何显示（数组）。我一直在看一个又一个的例子，但我一辈子都搞不明白这一点。我想知道PHP是否看到URL加载可能需要一点时间，并且等待的时间不够长

$context  = stream_context_create(array('http' => array('header' => 'Accept: application/xml')));
$url = 'http://api.ean.com/ean-services/rs/hotel/v3/list?cid=55505&minorRev=12&    apiKey=2hkhej72gxyas3ky6hhjtsga&locale=en_US&currencyCode=USD&customerIpAddress=10.184.2.9&customerSessionId=&xml=<HotelListRequest><arrivalDate>01/22/2012</arrivalDate><departureDate>01/24/2012</departureDate><RoomGroup><Room><numberOfAdults>1</numberOfAdults><numberOfChildren>1</numberOfChildren><childAges>4</childAges></Room></RoomGroup><city>Amsterdam</city><countryCode>NL</countryCode><supplierCacheTolerance>MED</supplierCacheTolerance></HotelListRequest> ';

$xml = file_get_contents($url, false, $context);
$xml = simplexml_load_string($xml);
print_r($xml);

$context=stream\u context\u create（数组（'http'=>array（'header'=>'Accept:application/xml'））；
$url='1http://api.ean.com/ean-services/rs/hotel/v3/list?cid=55505&minorRev=12&    apiKey=2hkhej72gxyas3ky6hhjtsga&locale=en_US¤cyCode=USD&customerIpAddress=10.184.2.9&customerSessionId=&xml=01/22/201201/24/2012114阿姆斯特丹NLMED'；
$xml=file\u get\u contents（$url，false，$context）；
$xml=simplexml\u load\u字符串（$xml）；
打印（xml）；

任何反馈都很好。谢谢

查看$url

在“&”和“apiKey”之间有一个空格，请首先删除该空格

我明白了：

<ns2:HotelListResponse xmlns:ns2="http://v3.hotel.wsapi.ean.com/">
  <EanWsError>
    <itineraryId>-1</itineraryId>
    <handling>RECOVERABLE</handling>
    <category>DATA_VALIDATION</category>
    <exceptionConditionId>-1</exceptionConditionId>
    <presentationMessage>
        Data in this request could not be validated: Specified arrival date is prior to today's date.
    </presentationMessage>
    <verboseMessage>
        Data in this request could not be validated: Specified arrival date is prior to today's date.
    </verboseMessage>
    <ServerInfo instance="71" timestamp="1394560288" serverTime="12:51:28.803-0500"/>
  </EanWsError>
  <customerSessionId>0ABAAA47-1A0E-8A91-44B2-24409C793B7A</customerSessionId>
</ns2:HotelListResponse>

使我的代码与您的代码不同的是，我绝对确保查询url中没有空格。

是的，当我复制和粘贴时，这只是一个格式问题。很抱歉是的，如果你将URL直接复制到浏览器中，这就是出现的内容，但是，我没有从上面的PHP代码中得到任何东西…令人沮丧。。。还是什么都没看到。然而，我看到显示“bool（false）”。我猜那是从“var_dump”来的。web服务器是否会导致此问题？我目前正在使用ipage。

$context  = stream_context_create(array('http' => array('header' => 'Accept: application/xml')));
$url = 'http://api.ean.com/ean-services/rs/hotel/v3/list?cid=55505&minorRev=12&';
$url.= 'apiKey=2hkhej72gxyas3ky6hhjtsga&locale=en_US&currencyCode=USD';
$url.= '&customerIpAddress=10.184.2.9&customerSessionId=&xml=<HotelListRequest>';  
$url.= '<arrivalDate>01/22/2012</arrivalDate><departureDate>01/24/2012</departureDate><RoomGroup>';
$url.= '<Room><numberOfAdults>1</numberOfAdults><numberOfChildren>1</numberOfChildren>';
$url.= '<childAges>4</childAges></Room></RoomGroup><city>Amsterdam</city><countryCode>NL</countryCode>'; 
$url.= '<supplierCacheTolerance>MED</supplierCacheTolerance></HotelListRequest>';

$xml = file_get_contents($url, false, $context);
$xml = simplexml_load_string($xml);
var_dump($xml);
