using functions from internal SOAP interface via php

Php comes with PHP SOAP libraries, that usually are included and enabled after a common php installation.

Yuo are asked to biuld the client part of the webservice pattern. Your partner should provide you the .wsdl of the web service. The wsdl describes the avialble method, the parameters they need and what they return.

Tipically parameters and return values are array structures

This could be a skeleton for your code:

 //build a client for the service
 $client = new SoapClient("partner.wsdl");

 //$client is now a sort of object where you can call functions
 //prepare the xml parameter
 $requestXML = array("parameter" => "<xml>Hello</xml>");

 //call the pull function this is like 
 $result = $client->__soapCall("pull", $requestXML );

 //print the value returned by the web service
 print_r($result);

Here follows a non-wsdl example First the location paramater is the address the SOAP request will be sent to. The uri parameter is the target namespace of the SOAP service. This is related to xml namespaces.

A sample code for you could be: //for URI specification you should watch your partners documentation. maybe also a fake uri (like mine) could work //build a client for the service $client = new SoapClient(null, array( 'location' => "https://justsomeurl.com:435/soap", 'uri' => "urn:WebServices", 'trace' => 1 ));

 // Once built a non-wsdl web service works as a wsdl one
 //$client is now a sort of object where you can call functions
 //prepare the xml parameter
 $requestXML = array("parameter" => "<xml>Hello</xml>");

 //call the pull function this is like 
 $result = $client->__soapCall("pull", $requestXML );

 //print the value returned by the web service
 print_r($result);
