如何使用 WSDL 和 PHP 请求 SOAP WebService

我现在遇到一个问题，我无法使用Web服务。这是我的网络服务的结构：

 array (size=22)
  0 => string 'struct TPAcess {
 TPKRequest KRequest;
}' (length=53)
  1 => string 'struct TPKRequest {
 AOIRequest REQUESTS;
}' (length=56)
  2 => string 'struct AOIRequest {
 TPIRequest REQUEST;
}' (length=57)
  3 => string 'struct TPIRequest {
 string ORDERID;
 string CPID;
}' (length=57)
  4 => string 'struct TPAResponse {
 TPKResponses KEYRESPONSE;
}' (length=63)
  5 => string 'struct TPKResponses {
 AOTPORequest REQUESTS;
 TPTechnicalError TECHNICALERROR;
}' (length=92)
  6 => string 'struct AOTPORequest {
 TPOutputRequest REQUEST;
}' (length=59)
  7 => string 'struct TPOutputRequest {
 string ORDERID;
 string CPID;
 ArrayOfTPSystem SYSTEMS;
 TPRequestError ERROR;
}' (length=107)
  8 => string 'struct ArrayOfTPSystem {
 TPSystem SYSTEM;
}' (length=44)
  9 => string 'struct TPSystem {
 int SYSTEMID;
 string PRODUCTLINE;
 ArrayOfTPOrder ORDERS;
}' (length=79)
  10 => string 'struct ArrayOfTPOrder {
 TPOrder ORDER;
}' (length=41)
  11 => string 'struct TPOrder {
 string TYPEOFORDER;
 string ORDERLABEL;
 string FIRSTSALEORDERLABEL;
 string NOPO;
 string PODATE;
 Applicant APPLICANT;
 ArrayOfCP CPS;
 AOSKey SKEYS;
}' (length=184)
  12 => string 'struct Applicant {
 int APPLICANTID;
 string APPLICANTNAME;
}' (length=61)
  13 => string 'struct ArrayOfCP {
 CPU CPU;
}' (length=31)
  14 => string 'struct CPU {
 string LABEL;
}' (length=29)
  15 => string 'struct AOSKey {
 SubKey SUBKEY;
}' (length=40)
  16 => string 'struct SubKey {
 string SUBKEYTYPE;
 ArrayOfEncryptCode ENCRYPTCODES;
}' (length=71)
  17 => string 'struct ArrayOfEncryptCode {
 EncryptCode ENCRYPTCODE;
}' (length=55)
  18 => string 'struct EncryptCode {
 string LABEL;
 string VALUE;
}' (length=52)
  19 => string 'struct TPRequestError {
}' (length=25)
  20 => string 'struct TPError {
 string CODE;
 string DESCRIPTION;
}' (length=53)
  21 => string 'struct TPTechnicalError {
}' (length=27)

以及我如何尝试从我的 PHP 函数访问它：

public function consumeWebService(){
    $client = new 'Soapclient('http://url_of_the_WebService?WSDL', array(
        'login'=>"myLogin",
        'password'=>"myPassword"
    ));
    $request = $client->TPAccess(array(
        'KREQUEST'=>array(
            'REQUESTS'=>array(
                'REQUEST'=>array(
                    'ORDERID'=>'numberOfMyOrderID'
                    )
                )
            )
        ));
        $result = $client->TPAccess($request);
        var_dump($result);die;
}

但我得到的唯一结果是：

object(stdClass)[280]
  public 'KRESPONSES' => 
    object(stdClass)[281]
      public 'TECHNICALERROR' => 
        object(stdClass)[282]
          public 'CODE' => string 'ERR_XML_001' (length=11)
          public 'DESCRIPTION' => string 'Core technical error preventing the message to be managed (e.g. invalid input file structure such as missing tag or mandatory value).' (length=133)

你们有什么想法吗？谢谢！
