How to use a webservice method with key
===

I'm trying to install and use a webservice in php.

I have the url : `http://cdt33.tourinsoft.com/soft/RechercheDynamique/Syndication/controle/syndication2.asmx`

And my code :

    $client = new SoapClient("http://cdt33.tourinsoft.com/soft/RechercheDynamique/Syndication/controle/syndication2.asmx?wsdl");
    
    $arFunctions = $client->__getFunctions();
    
    foreach ($arFunctions as $function) {
        echo $function.'<br/>';
    }

Here i can retrieve all methods of this webservice.

But i want to use this method : DataSet getListing(string $idModule), if i test with `idModule = dafda774-317d-4b5f-bb8b-33e5977dc13c` (my key) on the url, it works.

But I can not do it in PHP... any idea ?
