I'm trying to implement a Web Service running on an SAP PI system. The WSDL I got looks like this:

My PHP file looks like this (nothing more in it currently):
<?php
$client = new SoapClient('test.wsdl');
?>
When I'm running my script, I get the following error thrown:
Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Unknown required WSDL extension 'http://schemas.xmlsoap.org/ws/2004/09/policy' in /srv/www/htdocs/wsdl.php:2 Stack trace: #0 /srv/www/htdocs/wsdl.php(2): SoapClient->SoapClient('test.wsdl') #1 {main} thrown in /srv/www/htdocs/wsdl.php on line 2
I tried searching for the error on google and StackOverflow, and also checked the comments on php.net, but I can't seem to figure out what I'd have to change in order to get this Service running. I also tried to open the WSDL extension URL, it seems to exist.
Can someone throw me a bone here? I tried removing the extension URL, that results in the following error:
Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Unexpected WSDL element <UsingPolicy> in /srv/www/htdocs/wsdl.php:2 Stack trace: #0 /srv/www/htdocs/wsdl.php(2): SoapClient->SoapClient('test.wsdl') #1 {main} thrown in /srv/www/htdocs/wsdl.php on line 2
The only solution I can think of at this point is to update your UsingPolicy tag:
Change the tag:
<wsp:UsingPolicy wsdl:required="true"/>
to this:
<wsp:UsingPolicy wsdl:required="false"/>
