PHP web to call C4C API

I'm trying to create a PHP to enter lead information from a web and create into SAP C4C using the webservice API. I tried with the guide provided at

https://archive.sap.com/documents/docs/DOC-60770#

I installed Apache and PHP locally to run it. First error I got when I run the example PHP. I get this error when I search/create.

I changed the wsdl file

<wsp:UsingPolicy wsdl:required="true"/>

to

<wsp:UsingPolicy wsdl:required="false"/>

Then it hit this error. Tried with Proxy Enabled option also same.
I tested in SOAPUI, everything is working fine.

Try to contact or reply from the post but unable to do so. Anyone have any advice for this?
Thanks.
