我有一个看起来像这样的 SOAP 响应
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<GetShowInformationResponse xmlns="http://www.xxxx.com/xxxxWS/">
<GetShowInformationResult>
<CustomFields>
<CustomField>
<Name>string</Name>
<Value>string</Value>
</CustomField>
<CustomField>
<Name>string</Name>
<Value>string</Value>
</CustomField>
</CustomFields>
</GetShowInformationResult>
</GetShowInformationResponse>
</soap:Body>
</soap:Envelope>
我的 SOAP 调用为我提供了自定义字段的列表：
$result->GetShowInformationResult->CustomFields->CustomField
它的回答是这样的（虽然可能是对象或空）：
Array ( [0] => stdClass Object ( [Name] => YouTubeID [Value] => XPCHmIOml0f ) [1] => stdClass Object ( [Name] => Episode Title [Value] => Raw Foods ) )
我需要编写一个实用程序函数，该函数根据"名称"提取我想要的字段，然后给我"值"。这是我到目前为止所拥有的，但无法让它工作......
function ExtractCustomField($fieldName, $customFields) {
// $customFields might be an object, null, or an array.
$parsed = array();
if (is_array($customFields) == false && $customFields != null) {
$parsed = array($customFields);
} elseif (is_array($customFields)) {
$parsed = $customFields;
}
// loop through the fields and find the one we are looking for
$returnValue = null;
foreach($field as $customFields) {
if ($field->Name == $fieldName) {
$returnValue = $field->Value;
break;
}
}
return $returnValue;
}
ExtractCustomField('YouTubeID','$result->GetShowInformationResult->CustomFields->CustomField');
我很笨，@hakre帮我解决了。
问题是在foreach中混淆了变量，并且没有函数echo。还发现它是否返回了一个对象，我没有正确地将其放入数组中。
function ExtractCustomField($fieldName, $customFields) {
// $customFields might be an object, null, or an array.
if($customFields == null) {
$customFields = array();
} else {
$customFields = is_array($customFields) ? $customFields : array($customFields);
}
// loop through the fields and find the one we are looking for
$returnValue = null;
foreach($customFields as $field) {
if ($field->Name == $fieldName) {
$returnValue = $field->Value;
break;
}
}
return $returnValue;
}
echo ExtractCustomField('YouTubeID',$result->GetShowInformationResult->CustomFields->CustomField);
