什么是位置和uri在zend客户端非wsdl

Question

I used to make soap client in wsdl mode this way:

use Zend\Soap\Client;
$client = new \SoapClient('www.foo.com/api?wsdl');

and everything went good. Now I'm asked to use non-wsdl mode and given wsdl.xml file. To make it work. have to set up location and uri options. Can anyone explain what are these two options stand for and how to use them in my case??

Any help would be appreciated.

Thanks in advance.

Update
Can it be in wsdl mode using this file??
