從XML響應訪問數組部分的問題

Question

我正在發送一個XML URL以返回一些我已經設法顯示爲多個數組的數據。我發現很難區分一些特定的數據，並希望有人能夠教我如何正確地將這些數據添加到變量中。

下面是使用print_r();

SimpleXMLElement Object ([@attributes] => Array ([Status] => OK) [Errors] => SimpleXMLElement Object () [Warnings] => SimpleXMLElement Object () [RequestedCommand] => namecheap.domains.check [CommandResponse] => SimpleXMLElement Object ([@attributes] => Array ([Type] => namecheap.domains.check) [DomainCheckResult] => SimpleXMLElement Object ([@attributes] => Array ([Domain] => test.com [Available] => false [ErrorNo] => 0 [Description] => [IsPremiumName] => false [PremiumRegistrationPrice] => 0 [PremiumRenewalPrice] => 0 [PremiumRestorePrice] => 0 [PremiumTransferPrice] => 0 [IcannFee] => 0 [EapFee] => 0))) [Server] => PHX01APIEXT01 [GMTTimeDifference] => --4:00 [ExecutionTime] => 0.045) 

我通常可以管理陣列好嗎全陣列，雖然是「@屬性」在這裏被絆倒了我...這是我的腳本到目前爲止（裸記住我只是在這裏測試）。

$xml = simplexml_load_string($data); 
print_r($xml); 

echo '<br><br>'; 

$status = current($xml->attributes()); 
$results = $xml->DomainCheckResult->attributes(); 
echo $status['Status']; 
echo '<br><br>'; 

print_r($results); 

的$status變量工作和回聲的 'OK'。 的$results變量似乎只顯示「SimpleXMLElement對象（）」

我試圖瞄準這些專門 -

[Domain] => test.com [Available] => false [ErrorNo] => 0 [Description] => [IsPremiumName] => false [PremiumRegistrationPrice] => 0 [PremiumRenewalPrice] => 0 [PremiumRestorePrice] => 0 [PremiumTransferPrice] => 0 [IcannFee] => 0 [EapFee] => 0 

但我似乎無法得到遠遠超出我已經是誰？我將如何使用這些數據來獲得類似以下內容：

$domain_req = $xml[Domain]; 
$domain_avail = $xml[Available]; 

等等......？

按照要求，這裏是原始的XML -

<ApiResponse xmlns="http://api.namecheap.com/xml.response" Status="OK"> 
<Errors/> 
<Warnings/> 
<RequestedCommand>namecheap.domains.check</RequestedCommand> 
<CommandResponse Type="namecheap.domains.check"> 
<DomainCheckResult Domain="test.com" Available="false" ErrorNo="0" Description="" IsPremiumName="false" PremiumRegistrationPrice="0" PremiumRenewalPrice="0" PremiumRestorePrice="0" PremiumTransferPrice="0" IcannFee="0" EapFee="0"/> 
</CommandResponse> 
<Server>PHX01APIEXT03</Server> 
<GMTTimeDifference>--4:00</GMTTimeDifference> 
<ExecutionTime>0.018</ExecutionTime> 
</ApiResponse>

要訪問這些，你應該用...

$status = current($xml->attributes()); 
$results = $xml->CommandResponse->DomainCheckResult->attributes(); 
echo $status['Status']; 

$domain_req = $results['Domain']; 
$domain_avail = $results['Available']; 

你必須使用引號一輪的名字。
