Headers for connecting to a SOAP webservice using PHP - php

Question

I am trying to connect to a SOAP webservice using php. I am very new to using php.
I can connect to the service, the test below returns a list of all the available functions of the webservice.
$url = "http://...client_ip.../dkServiceDefault/dkWSItemsCGI.exe/wsdl/IItemService";
$client = new SoapClient($url);
var_dump($client->__getFunctions());
If I try to access one of these functions(ex. NumberOfModifiedItems) then I get an error stating that I need to supply a SOAP header with a username and password.
According to the documentation of the SOAP service the header needs to look like this:
<soap:Header>
<q1:BasicSecurity id="h_id1" xmlns:q1="urn:dkWSValueObjects">
<Username xsi:type="xsd:string">username</Username>
<Password xsi:type="xsd:string">password</Password>
</q1:BasicSecurity>
</soap:Header>
How can I make this header in php? How do I attach it to the SoapClient? I have a username and password but I can't figure out how to create the exact header to send to the webservice. I have tried following several tutorials, but I just can't seem to get it to work.

You may pass SOAP headers with SoapHeader class and SoapClient::__setSoapHeaders method:
<?php
$url = "http://...client_ip.../dkServiceDefault/dkWSItemsCGI.exe/wsdl/IItemService";
$client = new SoapClient($url);
$namespace = "urn:dkWSValueObjects";
$authentication = array(
'Username' => 'yourname',
'Password' => 'yourpassword'
);
$header = new SoapHeader($namespace, 'BasicSecurity', $authentication, false);
$client->__setSoapHeaders($header);
var_dump($client->__getFunctions());
?>
