SOAP请求与PHP SoapClient的（嵌套头）

Question

我想产生一个SOAP头类似下面

<SOAP-ENV:Header> 
<RequesterCredentials xmlns="urn:ebay:api:PayPalAPI" xsi:type="ebl:CustomSecurityHeaderType"> 
<Credentials xmlns="urn:ebay:apis:eBLBaseComponents" xsi:type="ebl:UserIdPasswordType"> 
<Username>api_username</Username> 
<Password>api_password</Password> 
<Signature>api_signature</Signature> 
<Subject>authorizing_account_emailaddress</Subject> 
</Credentials> 
</RequesterCredentials> 
</SOAP-ENV:Header> 

参考：https://developer.paypal.com/webapps/developer/docs/classic/api/PayPalSOAPAPIArchitecture/

我尝试做以下事情产生这种结构，

$credentialsHeader = new SoapHeader("urn:ebay:apis:eBLBaseComponents", "Credentials", 
        array(
          "Username : username.user.name", 
          "Password : password", 
          "Signature : signature", 
          "Subject : my_email_id" 
              )); 
$requesterCredential = new SoapHeader("urn:ebay:api:PayPalAPI", "RequesterCredentials", $credentialsHeader); 

$client->__setSoapHeaders(array($requesterCredential)); 

但我得到一个错误：

{main}Authentication failed. API credentials are incorrect. 

我假设我正在做错的方式，我正在形成标题？对此的一些见解或帮助将会很大。

它应该是这样的：

$credentialsHeader = new SoapHeader("urn:ebay:apis:eBLBaseComponents", "Credentials", 
       array(
         "Username" => "username.user.name", 
         "Password" => "password", 
         "Signature" => "signature", 
         "Subject" => "my_email_id" 
             )); 
$requesterCredential = new SoapHeader("urn:ebay:api:PayPalAPI", "RequesterCredentials", $credentialsHeader); 
$client->__setSoapHeaders(array($requesterCredential));
