Question

I\'m attempting to write a PHP script that will connect to the SOAP client for our SightMax interface. With the code below I am able to print out a list of functions availa

WCF seems to be looking for the action in the SOAP envelope. You can add it to your call with PHP's SoapClient this way:

$actionHeader = new SoapHeader('http://www.w3.org/2005/08/addressing',
                               'Action',
                               'http://soapaction.that.was.in.the.wsdl');
$client->__setSoapHeaders($actionHeader);

If you change the third parameter and add that between your instantiation of $client and the __call() it should clear the error (and possibly bring on new ones, isn't SOAP fun?)

Also FYI, having just gone through this same problem, I found the __getLastRequestHeaders(), __getLastRequest(), __getLastResponseHeaders(), and __getLastResponse() functions very handy to see if what I was trying had any effect (note that you need to add "trace" => "1" to your SoapClient options for those to work.)
