Switching from NuSoap to PHP5 Soap - need a jumpstart

Question

Here's the call I'm trying to make:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Header xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <urn:SessionHeader  xmlns:urn="http://www.mywebservice.com/webservices/SoapService" xmlns="http://www.mywebservice.com/webservices/SoapService" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
        <urn:sessionId xmlns:urn="http://www.mywebservice.com/webservices/SoapService">LOGINTOKEN=your instance name</urn:sessionId>
    </urn:SessionHeader>
</soap:Header>
<soap:Body xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <ns2:login xmlns:ns2="http://www.mywebservice.com/webservices/SoapService">
        <wsUser>
            <entityId>0</entityId>
            <password>your password</password>
            <username>your username</username>
        </wsUser>
    </ns2:login>
</soap:Body>

But I'm having trouble finding out how to set up the custom headers in PHP5's Soap. With nuSoap I could just put the whole thing into a variable and then use $client->setHeader($headerVar) but I can't find anything similar in PHP. If I could replicate this one call, I can figure the rest out. Any help would be appreciated!

Thanks in advance!

Update: I've gone through tutorial after tutorial, and read the PHP docs, but nothing seems to work. I can do what I want with curl (as well as nuSoap) but I thought the native PHP5 Soap would be easier and possibly more stable. I guess not...

Update 2 Here's the code I'm trying:

$soapurl = 'http://www.mywebservice.com/webservices/SoapService?wsdl';
$client = new SoapClient($soapurl,array('trace'=>true));
$token = "LOGINTOKEN=your instance name";

$header = new SoapHeader('http://www.mywebservice.com/webservices/SoapService', 'SessionHeader', array('sessionId' => $token));
$client->__setSoapHeaders($header);


$client->login(array("wsUser" => array('entityId'=>'0','username'=>'my username','password'=>'my password')));

And the error I get:

**Fatal error**: Uncaught SoapFault exception: [ns1:InvalidSecurity] An error was discovered processing the <wsse:Security> header in C:\www\soap\index.php:12 Stack trace: #0 C:\www\soap\index.php(12): SoapClient->__call('login', Array) #1 C:\www\soap\index.php(12): SoapClient->login(Array) #2 {main} thrown in C:\www\soap\index.php on line 12

Update 3 So it looks like the "sessionId" is being sent as "key" with the token sent as "value".

 *REQUEST*:
    <?xml version="1.0" encoding="UTF-8"?>
    <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://www.mywebservice.com/webservices/SoapService">
<SOAP-ENV:Header>
<ns1:SessionHeader><item><key>sessionId</key><value>LOGINTOKEN=my token</value></item>
</ns1:SessionHeader>
</SOAP-ENV:Header>
<SOAP-ENV:Body><ns1:login><wsUser><entityId>0</entityId><password>my password</password><username>my username</username></wsUser></ns1:login></SOAP-ENV:Body></SOAP-ENV:Envelope>

Answer 1

Have you tried the SoapHeader class to construct your header? Would something like this work?

//Assume $token holds your login token and $client holds the SoapClient object
$header = new SoapHeader('http://www.mywebservice.com/webservices/SoapService', 'SessionHeader', array('sessionId' => $token));
$client->__setSoapHeaders($header);

That should create the header and add it to the SoapClient. Every subsequent call using the SoapClient will then have that header set. As to the exact format, I wouldn't worry too much. You sample XML uses an alias for the namespace called urn. PHP probably won't arrive at exactly the same alias but it should still work. Also I don't think that declaring the xmlns in every child element is needed. I think that a child node automatically inherits the namespace of its parent in XML, but I'm not 100% certain on that. The bottom line is that as long as the right URL's are declared in the namespaces it should be fine even if the XML doesn't exactly match your example.

One other thing you could try-have you switched on tracing in the SoapClient? This is one of the parameters that can be passed to the constructor and it enables you to view the XML SOAP requests and responses. If it still doesn't work using the SoapHeader class try switching tracing on to see what's being sent and received.
