Wsdl to PHP: Can't import schema error for xml-exc-c14n

Question

I am trying to generate a php file from a wsdl file using wsdl2php.php script. Previously when I was not using WS-Security in SOAP Service, everything was fine.

Everytime when I run the script, I am getting the error:

PHP Fatal error: SOAP-ERROR: Parsing Schema: can't import schema from 'http://www.w3.org/2001/10/xml-exc-c14n#'

I dont know whether any php library or package is missing or not... Can anyone help me out?

My wsdl file looks like:

<types>

 <schema targetNamespace="http://tempuri.org/myService.xsd"
  xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
  xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"

Have you tried to open the url http://www.w3.org/2001/10/xml-exc-c14n# in your browser? You'll see that it points to a webpage and not a schema as the next one http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd does. In any case, using wsdl2php or WsdlToPhp will fire you this error.
