Answer 1

Nowadays, the best way to consume SOAP WS in PHP is to use a WSDL to PHP such as the PackageGenerator project which will generate the classes to construct the request, then to send the request then to handle the response all that using PHP objects. The generated classes are sufficiently intuitive to construct the request. In addition, it uses composer as the autoloader.

Answer 2

kind of resolved the issue, the problem was with the <token></token> part.
Since it needs a value of type:guid <Id>guid</Id> that as mentioned in the wsdl and xml request, is a dataset created by a .Net library, and it's used to iterate over the samples, it's quite a complicated request, since it needs previous steps to be fulfilled, so i did the request, by omitting the <token> section
