在PHP中将XML转换为数组以调用Soap API

$xmlString = '<root><name>John Doe</name><age>30</age></root>';
$xml = simplexml_load_string($xmlString);

$xmlString = '<root><name>John Doe</name><age>30</age></root>';
$dom = new DOMDocument();
$dom->loadXML($xmlString);

function xmlToArray($xml) {
    $result = [];
    
    if ($xml instanceof SimpleXMLElement || $xml instanceof DOMDocument) {
        foreach ($xml as $key => $value) {
            if (count($value->children()) > 0) {
                $result[$key] = xmlToArray($value);
            } else {
                $result[$key] = strval($value);
            }
        }
    }
    
    return $result;
}

// 使用SimpleXML对象转换为数组
$array = xmlToArray($xml);

// 使用DOMDocument对象转换为数组
$array = xmlToArray($dom);

$client = new SoapClient("http://example.com/soap.wsdl");

// 构造请求参数数组
$params = [
    'param1' => 'value1',
    'param2' => 'value2',
    // ...
];

// 转换为Soap对象
$soapParams = new SoapVar($params, SOAP_ENC_OBJECT);

// 调用Soap API
$response = $client->__soapCall('methodName', [$soapParams]);
